Elizabeth Mines 7.0 MW Landfill Solar Array

Strafford, VT

The Elizabeth Mine Site is one of the largest historic mining sites in New England located between the towns of Strafford and Thetford, Vermont.

As part of a complex Superfund effort to clean-up and stabilize the abandoned copper mine, Greenwood Energy, codeveloper and now owner of the solar installation, contracted Conti Solar to engineer, procure, and construct the 7 MW ballasted solar project.

Installation strategies and logistics were communicated thoroughly with the Environmental Protection Agency (EPA) and Vermont Agency of Natural Resources (VANR) to limit any impacts to the recently capped Superfund landfill.

The Elizabeth Mines Solar project was the largest PV solar installation in the State of Vermont at its time of completion. The system contains over 2,200 ballast blocks, 20,000 PV modules, and three Concrete Integrated Central Inverter Skids. Conti Solar had calculated, communicated, and orchestrated the staging and movement of all materials and labor across the landfill cap to ensure the construction plan was being adhered precisely to specifications. Conti Solar managed local contractors to complete the project under budget and over a month ahead of schedule.

Due to the remote location of the project, over 500 tractor trailers were piloted and escorted from the Interstate Highway through 10 miles of Vermont country roads within the towns of Sharon, Thetford, and Strafford. Conti Solar had conducted the network of flagmen, police details, detours, pilot cars, and permitting to ensure the safety of the residents and protection of the local infrastructure.

Eversource 44 MW Solar Portfolio

Massachusetts

Eversource, the largest utility in NH, MA and CT, was approved by their state regulators to develop, construct and operate 44MW of solar facilities across all of MA to directly save their rate payers money.

In the project, Conti Solar was chosen to build 44MW across fifteen Solar Projects, ten of which were commissioned in 2017. The remaining five projects were commissioned in first half of 2018. Conti’s scope was to Engineer, Procure, Construct and Commission the projects. With this, the primary goal of the Eversource Portfolio was to save rate payers money by building cost competitive solar projects.

All projects regardless of their start date, needed to be mechanically complete by the end of December 2017. Conti was successful in meeting this milestone and did it with outstanding safety record and highest quality standards. 

Compared to other projects, this portfolio faced varied challenges resulting from an aggressive timeline of developing a project to its mechanical completion. Typically, a solar project’s development cycle is two years in MA before it goes through the EPC phase, but these projects were fast-tracked and were being developed and built in a compressed timeline. This required intense collaboration with the owner, its development and consultant teams, Conti’s vendors and subcontractors.

Middleton Solar Park 6.0 MW Ground Mount

Middleton, MA

Conti Solar was contracted by Falck Renewables to design, procure and install a 6.0 MW ground mount solar array in the 100-year-old Richardson Dairy Farm.

Decades before, the site had been a gravel pit with approximately 80% of solid ledge.  Conti Solar had to predrill all the foundation screws, pull out numerous large rocks when trenching for wiring and break up solid areas. In some locations, the ledge was continuous, so the team had to lay the conduit at the surface and cover it with concrete to avoid the substantial costs of hammering the whole area.

The Middleton Solar Park’s stony terrain and extreme weather required Conti Solar to conquer the elements not just once, but continually while constructing the 16,000 solar panel project. The site was affected by three nor’easter storms in March and the snow cover made it difficult for the crew to work efficiently but with great teamwork the site was successfully completed.

This project delivers the preferred resource of renewable solar electricity to Middleton Electric Light Department under a long-term power purchase agreement.  It also allows the city to sell Renewable Energy Credits, in addition to qualifying for the federal Investment Tax Credit Incentive (ITC).  

Although snowstorms and underground rocks made every aspect far more difficult and laborious, Conti Solar solved every issue and succeeded in bringing solar to the 100-year-old Richardson Dairy Farm site.

Old Bridge Solar 10.7 MW Ground Mount

Keyport, NJ

Conti Solar was contracted by NJR Clean Energy Ventures III Corporation to design, procure and install a 10.7MW post mounted array between October 2017 and April 2018.

Work consisted of installation of almost 2,561 posts for the solar array, racking and installation of approximately 27,072 LG solar modules. Conti’s work also entailed the DC and AC work associated with the solar array including the setting of four SMA central skid inverters and a PowerGrid Solutions switchgear at the point of interconnection.

Prior to the installation of the solar facility, Conti had to clear 31 acres of land and import 22,000 cubic yards of clean fill.  The clean fill was used to “cap” the brownfield site, which was previously used as a brick manufacturing facility.

Conti Solar constructed the array throughout the winter months with little to no impact to overall schedule durations. Through our detailed preplanning process, we were able to schedule our work around the weather and keep the progress of the site moving despite weekly snow and rain events throughout the particularly harsh winter.

Conti Solar’s work on this site helped convert a previously unusable brownfield into useable property which now generates renewable energy.  This work directly impacted the community by remediating a large contaminated property that was adjacent to schools and homes. Additionally, the green energy produced directly benefits the local community as the energy produced by the solar array will be used to power homes in the local community.

Citizens Solar contracted Conti to engineer, procure and construct this 3.5 MW ground mount system on this former landfill in Tyngsborough, Massachusetts.

Citizens Solar develops, finances, constructs, owns and operates utility-scale projects that generate green energy, produce a positive local economic impact and create local jobs.

Conti built the system on a concrete ballasted system with five different weights of ballast blocks and sixteen different span lengths that each had to be set and leveled on gravel foundations due to the unique terrain of the landfill.

Conti installed 10,279 solar modules, 3,101 ballast block foundations, 542 strings of 19 panels divided into 72 string inverters and combined again into 14 secondary panel boards and three step up Sunbelt transformers (800KVA, 1000KVA, 1000KVA).

Since the site shares a border with both Tyngsborough and Dunstable, it required two interconnections and two active building permits with separate inspections. The Dunstable side contains 40 percent of the system and goes through a single transformer, while the remaining 60 percent is in series on the Tyngsborough side. The system is grounded with 112 ground plates and rods.

Conti self-performed construction of the gravel access road, culvert installation and electrical road crossings, with a crew dedicated to leveling and setting the ballast block foundations. This multi-step process involved strategic material placement and careful coordination to bring the blocks from a nearby staging area, place them within the field and lift, level and set each block into position.

PanAm 6 MW Solar Ground Mount System

Billerica, MA

Turning contaminated land into a clean energy generating facility, Conti transformed a once unusable space into a source of power for the neighboring community.

Conti installed the 6 MW array on a site containing and asbestos landfill and rocky terrain. This required different skill sets to ensure the array could be installed per design criteria without impacting the integrity of the landfill cap.

Conti utilized a combination ballasted and post-driven racking system developed by RBI Solar for this project. The array was constructed using JA Solar 345 and 350 watt modules and Sungrow string inverters. The location of the array contained high ledge rock, which presented challenges for the installation of foundations and underground wiring.

Conti managed 10 subcontractors in the implementation of this project, which included heavy clearing, earthwork import and site grading, solar array construction, fencing and medium voltage installation, all while meeting the owner’s schedule and budget.

Conti implemented a design for the post driven racking system to reduce the cost of the project for the owner. Instead of screw type posts, Conti executed a rock drilling operation allowing for installation of traditional driven posts, saving both time and money for the project.

Utilizing a rock drilling technic not commonly found in the solar industry, Conti executed this project on time and on budget.

Bernards Landfill Solar 3.67 MW Ground Mount

Bernardsville, NJ

This large solar array was built on an 18-acre municipal landfill owned and operated by the Bernards Township. Conti was contracted by New Jersey Resources Corporation to provide turnkey engineering, procurement, permitting and construction services for this project.

Conti obtained necessary township planning board approvals, New Jersey Department of Community Affairs permits, county soil conservation permits, New Jersey Department of Environmental Protection approvals and township building and electrical permits for the project.

The project was built while an onsite recycling center remained operational, which created logistical challenges as access to the site was limited and there were landfill cap load restrictions. With careful planning, appropriate equipment selection for operations on the landfill and close coordination with the township’s operations team, Conti successfully completed the installation on time and within budget.

Conti installed over 1,000 concrete ballasts of varying sizes to meet the township’s design criteria and support 11,495 Canadian Solar 320 W modules. This project utilized 121 SMA 24 kW string inverters from which AC feeders were fed to the distribution panelboards via carefully designed cable tray system. The system was interconnected with Jersey Central Power & Light’s (JCP&L) and PJM’s 12.47 kV grid network. The entire solar array is protected via a 3,900-foot permanent perimeter fence.

With the final approvals from the owner and Bernards Township, this project was successfully put in operation in September 2016.

Battery Energy Storage System

King of Prussia, PA

Utilizing next generation battery technology, Conti engineered and constructed a battery energy storage system interconnected to the PJM grid for use in the Frequency Regulation Market.

Conti constructed the battery energy storage system (BESS) which supplied loss of grid power to Aqua’s water treatment facility as well as the provision of 800kW of frequency regulation ancillary services to PJM. This project allowed for the continuous operation of the water treatment facility during grid outages as well as local grid stabilization measures for PJM. The system serves two client’s needs while providing a steady revenue stream for the system owner.

The BESS was interconnected to Aqua’s water treatment plant at a voltage of 2.4 kV AC utilizing a 2.4 kV Switchgear. In addition, as part of PECO’s interconnection requirements, a neutral grounding transformer was installed at on the plant’s incoming feeder to make it effectively grounded.

The entire system was controlled via a sophisticated SCADA system which operated the BESS in loss of grid mode or frequency regulation mode. This switching utilized high-speed disconnect switches while the system set voltage and frequency as a lead or followed grid voltage and frequency in lag mode.

Conti’s first battery storage project was a success for our client and paves the way for future solar + storage opportunities.

Lumberton 9.5 MW Solar Ground Mount System

Lumberton, NJ

As a new investor in the United States solar market, GD Development was looking for the top EPC contractor to complete the Lumberton Solar Project. After an exhaustive search, they chose Conti as their partner.

Conti designed and constructed two adjacent arrays interconnected at 13.2 kV totaling 9.5 MW, managing all aspects of the project, including grid interconnection, utility coordination and state, county and township approval. Conti cleared the 40-acre site and installed the over 33,000 photovoltaic (PV) modules and 12 inverter skids in the array. Special considerations were made during construction as the site contained historic grounds as well as wetlands.

Conti worked with local, county and state officials to construct the array in accordance with inspectors’ requests while meeting the difficult schedule demands of the project. The original design called for interconnection at 69 kV, however, due to schedule and constructability concerns it became clear this interconnection could not be completed in the project’s timeframe.

In response, Conti worked with utility companies PJM and PSE&G to re-engineer the interconnection voltage to 3.2 kV. Conti also worked with PJM to perform feasibility and impact studies on an accelerated basis, starting construction within months of finalizing design details and applications. This proactive redesigning allowed for on time project completion and saved the owner over $500,000.

Working with the utility to modify the interconnection voltage for the project, Conti was able to save the project owner money and complete the construction on schedule.

Smithsonian Solar 0.6 MW Ground Array

Front Royal, VA

The Smithsonian Conservation Biology Institute (SCBI) was formally a U.S. Army Cavalry Remount Station and was used to train horses, mules and K-9s for military use during World War I and II.

It was later donated to the Smithsonian for research and conservation efforts for wildlife and ecosystems. Constellation contracted Conti to clear the site and engineer, construct, and commission a 600kW solar facility at the institute.

Conti worked on a site surrounded by endangered, highly endangered and extinct in the wild animals. With many animals mating and birthing seasons occurring in the spring and summer, Conti pushed to build and interconnect the project during the Winter months to minimize the impact on the neighboring animals. The team kept the project on schedule and budget despite these obstacles by closely managing vendor and subcontractor schedules, and completing the interconnection work first, instead of last, due to the mating season.

Conti self-performed the civil work, posts, racking and panel installation while managing three subcontractors throughout the project, including electrical engineers, electrical subcontractor and fencing installer.

Constellation will own and operate the array for 23 years, allowing the Smithsonian to operate their 3,100-acre facility on a lower carbon footprint and conserve their funds to allow more research and reproduction of our world’s endangered animals.

Conti designed and constructed the largest solar carport in the state of Ohio, one of the largest in the Midwest.

Recognized as a leader in sustainable practices, Owens Corning is one of the world’s oldest producers of insulation and fiber glass. The firm sought to upgrade the parking areas at its world headquarters with a new, largest-of-its-kind solar energy installation. The request for Conti’s services by Owens Corning, in coordination with Constellation Energy, directly supported the company’s corporate goals to reduce its environmental impact.

Conti was responsible for the design, engineering, procurement, construction and installation of the 2.4 MW DC photovoltaic (PV) double truss carport solar array to interconnect with the Owens Corning building. Conti performed turnkey services including design and installation of the foundations, steel canopy structures, decking, snow guards, lighting, interconnection, AC and DC feeders, DC disconnects, inverters and panelboards, as well as modifications required to the three existing switchgears feeding the building to interconnect the solar facility.

Construction of the array was accomplished in two phases, since half of the existing parking lot needed to remain active for Owens Corning’s employees and visitors. Due to variations in the subsurface foundation (the site was previously used as a railroad yard), design and installation were the biggest challenge on the project. Conti accomplished this project successfully by partnering with both engineering firms and working hand-in-hand with the racking system supplier to find the best solution for design, cost and schedule. The project interconnected on-time and both phases were completed as planned.

Rehoboth 2.4 MW Landfill Ground Array

Rehoboth, MA

Conti helped the Town of Rehoboth convert their town-owned landfill to an efficient solar energy facility generating significant revenue for them.

After the home-rule petition was passed by the Massachusetts Legislature and signed into law, allowing the Town of Rehoboth to collect and reallocate funds generated from local solar farms to the town’s capital improvements, Rehoboth representatives contracted Conti to design and build a solar farm on the Rehoboth Landfill. The solar plant helps town and state officials capitalize on the new legislation to raise funds for badly needed community infrastructure upgrades, including repairs to the Town Hall and police station.

Conti designed, engineered, procured and installed the 2.4 MW solar array on the landfill near an operational transfer station. With slopes of varying degrees and topping out at 13%, the topography of the Rehoboth landfill posed significant challenges. Conti worked with the landscape by developing project designs early on and redesigning when necessary. Conti also used an innovative Game Change racking system which allowed the team to attach solar panels to the landfill without penetrating it by using concrete blocks over posts.


Working closely with project stakeholders, local vendors and subcontractors, the team was able to complete the project on budget and on schedule in just three months with minimal rework and redesign needed. Once completed, Conti connected the new energy system directly to National Grid’s distribution system.

The team received the Best Project Award of Merit for outstanding performance in the Energy/Industry category from Engineering News-Record.

Representative Steven Howitt said, in a statement to the press, this new solar array and others like it present “a smart and prudent way of separating some of the money [from solar energy creation] and putting it from the solar farms into a separate fund for capital improvement.”

Perryman 5.4 MW Ground Array

Aberdeen, MD

The new array generates enough electricity to meet approximately 20 percent of the Archdiocese of Baltimore’s electricity needs.

After Pope Francis invited the Catholic Church to take steps to promote sustainability, the Archdiocese of Baltimore took immediate action by commissioning the construction of a new 5.4 MW solar array at Perryman Station in Harford County, Maryland. Constellation Solar, one of Maryland’s leading electrical utilities, hired Conti to design and construct the new system.

Conti performed engineering and construction services for the ground mounted photovoltaic (PV) system. The team completed the project on a very tight two-month schedule despite having to relocate to a different site early on. The installation was originally planned for a site in Sykesville, Maryland when Perryman was deemed more suitable. This called for extensive re-engineering, including redesign of the electrical package and racking layout to incorporate an additional 33 kV Eaton Switchgear lineup.


The solar PV system was made up of 17,708 panels, 932 pre-wired strings and two inverter skids with three inverters each on 17 acres of land. The project also involved the installation of underground conduits under and around high pressured gas lines and water lines.

Now that Conti has completed the project, the Archdiocese is purchasing the electricity generated by the solar panels from Constellation under a 20-year Power Purchase Agreement.

“This new solar power system will allow us not only to better manage our energy costs and devote more funding to the many important programs and ministries we have in place to support our community,” said the Archdiocese of Baltimore William E. Lori, “But also to educate our parishioners about sustainable initiatives.”

USACE Israel Air Base 5 MW Ground Array

Israel

Conti’s first international solar project, this 5MW system is helping the Israeli army kick-off their long-term renewable energy initiative.

One of the largest organizations in Israel is working hard to improve energy usage. Dubbed “Blue Going Green,” the Israeli Defense Force launched a program to reduce the country’s carbon footprint and reliance on fossil fuels by building new solar installations at as many air force bases as possible.

The ambitious program seeks a net-zero-energy air force by the end of 2033, so Israel’s army and air force bases would produce almost all their energy from solar sources and institute a wide range of other environmentally-friendly technologies. The first solar-based air force facility to come online is a major base in southern Israel.

Conti designed and constructed the photovoltaic power plant with a DC power rating of 5 MW. The plant includes a weather station tied into the solar system’s communication infrastructure and is equipped with sensors to measure and monitor irradiance, temperature and wind speed.

The project team’s work on the secure, active air force base required significant security protocols and coordination with the US Army Corps of Engineers and Israeli air force base personnel. Conti’s site security officer worked daily to make sure operations were performed in accordance with the base’s tight security specifications.

PSE&G Parklands 10.1 MW and Kinsley 11.2 MW Landfill Ground Arrays

Sewell & Bordentown, NJ

As part of PSE&G’s Solar 4 All Program, these projects were among the first to transform otherwise unusable landfill space into solar generating facilities.

As part of New Jersey’s Solar Act of 2012, the New Jersey Board of Public Utilities established a program to encourage solar utility companies and contractors to redevelop existing lands into solar generation facilities. PSE&G, one of the nation’s leading solar utility providers, developed its Solar 4 All Program to convert landfills around New Jersey into solar farms. With Conti’s help, these first-of-its-kind projects are profitable and beneficial to the communities they serve.

Conti engineered, procured and constructed two of PSE&G’s largest solar photovoltaic (PV) systems: a new ballasted ground array on a former reclamation sanitary landfill in Bordentown, New Jersey, and its largest, most beneficial public brownfield redevelopment to date in Sewell, New Jersey’s Kinsley Landfill. Both sites were highly publicized in their communities due to the negative impacts of those landfills. Malodors, groundwater contamination and political battles around how to handle the land had left Kinsley and Parklands with controversial histories and in need of positive change.

Conti helped PSE&G turn these sites into benefits for their communities as production centers of clean, renewable energy. The project teams provided permitting support, engineering, procurement, construction, interconnection, commissioning, testing and startup as a complete turnkey package to PSE&G on both projects.

At Parklands, Conti engineered and constructed a 10.1 MW ballasted ground mount array producing more than 14 million kWh. Conti provided a customized ballasted racking system and installation process to ensure the integrity of the existing cap was not compromised. At Kinsley, Conti engineered and constructed a 11.2 MW solar array also producing more than 14 million kWh. The team provided a suitable final grade for the array by importing and placing close to 100,000 tons of clean fill material on the site. Quick and efficient solutions like these enabled Conti to finish this highly publicized project two months ahead of schedule.

Both projects generate enough electricity to power over 3,500 homes annually.

NAVFAC Barstow 2 MW Ground Array

Barstow, CA

NAVFAC’s first ever solar PPA, Conti owns and operates this system to provide the military with significant electricity savings.

Naval Facilities Engineering Command (NAVFAC) teamed with Conti to create its first ever solar project using a long-term Power Purchase Agreement (PPA) to provide the Marine Corps with significant electricity savings.

Operating at net zero power from the grid had long been a goal of the US Marine Corps Logistics Base located in the Barstow desert of California. To address this, Conti worked closely with NAVFAC to develop special federal legislation enacted by Congress for a long-term PPA on a military base. The legislation, “Contracts for Energy or Fuel for Military Installations,” requires no upfront capital investment from the government. Barstow was the first solar project to use this legislation, and Conti successfully lined up the financing to make the project possible.

Under the PPA, Conti owns the project and sells the power generated to the Marine Base. The project supplies about 25% of the base’s electricity requirements and is expected to provide the Marine Corps with $3.9 million in energy savings over the 20-year term of the PPA. There are significant environmental benefits as well. The project offsets the release of 18,000 tons of greenhouse gas, which is equivalent to planting 28,000 trees and growing them for ten years.

Conti also engineered, procured and constructed the array. The solar photovoltaic (PV) system consisted of 4,452 solar panels at two separate locations on the base, generating 2.5 million kWh of electricity in the first year of operation. At the Yermo site, the 771 kWh facility consists of 2,968 modules in 212 14-panel DC electrical strings feeding two Advanced Energy 333 kW inverters. The Nebo system has a maximum DC capacity of 386 kWh and uses 1,484 modules in 14 panel DC electrical strings to feed one Advanced Energy 333 kW solar inverter. The Nebo installation had unique challenges due to the existing 1 MW wind turbine.

Conti designers developed a solution to overcome the 1 MW cap on net metering by installing relays to limit production of the PV system. Once the DC power is sent to the grid-tie inverters from both locations, it is converted to AC and stepped up to 12.47 kV to feed the base’s local distribution.

Conti successfully negotiated a solar PPA with the US Navy, one of the first of its kind, which required significant engagement with the Secretary of the Navy’s office to achieve a financeable agreement.

Conti designed, engineered and constructed one of the largest solar projects in New England on an incredibly fast track schedule.

One of the foremost solar energy developers in the eastern US, Blue Wave Capital worked for several years to develop the highly complex Barrett Street project before contracting Conti to design, engineer and construct one of the largest solar projects in New England on an incredibly fast track schedule.

Conti worked on 12 uniquely-shaped mini-arrays spread out in between wetlands across the 130-acre site which presented logistical challenges with only one roadway in and out. To keep the project on schedule and budget, the team closely managed trucking traffic and worked on multiple arrays concurrently. Conti also built access roads, culverts and swales and performed general site grading, boring pit drilling and structural demolitions while managing close to 230 personnel at peak and 20 subcontractors throughout the project, including electrical engineers, demolition specialists and Conti’s long-time racking and photovoltaic (PV) module supplier and installer, RBI Solar.

During construction, the team performed work in accordance with the specifications of Blue Wave Capital and the Town of Oxford, whose Conservation Commission, Building Inspection department and Electrical Inspection department, along with a third party Oxford inspector, monitored the project regularly.

Once construction was complete, Conti tied the PV system into the existing National Grid distribution system. Blue Wave Capital will own and operate the array for 20 to 25 years.

One of the largest projects in Massachusetts, Conti worked through challenging site conditions with a very aggressive schedule to complete this project on time.

Rutgers 8.8 MW Parking Canopy Array

Rutgers, NJ

Faced with rising energy costs, Rutgers University contracted Conti to construct the nation's largest solar car canopy on a university campus.

Conti designed and constructed two solar arrays over 32 acres of parking lot for Rutgers University, which at the time of construction was the largest renewable energy system ever built on a college campus in the US, producing 8.8 MW of electricity for the University.

Faced with steadily rising conventional energy costs, Rutgers University turned to solar for a solution. Environmental stewardship is taken seriously at Rutgers, so the University’s Board of Governors decided to outfit its parking lots with one of the largest solar canopy energy systems in the nation.

Conti engineered, procured and constructed the solar photovoltaic system, designed using a Yingli Solar 260-watt Panda monocrystalline, high-efficiency module for greater kWh output, increasing the number Solar Renewable Energy Credits (SRECs) earned over the life of the system.

The University financed the project via an arrangement with Key Bank, which is leasing the equipment to Rutgers for 20 years and taking the tax incentives while Rutgers maintains the SRECs. The project will be paid for by a combination of electrical savings and New Jersey SRECs, which can be sold to electric suppliers as a source of revenue to the University. Rutgers University estimates the value of the SRECs and savings in electricity to net $28 million over the 20-year period.

Jets Training Center 750 KW Rooftop Array

Florham Park, NJ

Green is not only the New York Jets team color but its philosophy for energy conservation. Conti installed a rooftop solar system at the Jet's Atlantic Health Training Center, the largest of any NFL team.

Conti completed a solar electric generation system at the NY Jets headquarters and training center in Florham Park, NJ. The system, funded through a power purchase agreement, is saving the Jets tens of thousands dollars each year in electricity expenses with no capital outlay.

Conti installed 3,000 solar panels to the facility’s standing seam metal roof using a completely non-invasive, non-penetrating mounting system. The system is designed to generate over 750,000 kWh of electricity each year and will reduce CO2 emissions by 540 metric tons each year, equivalent to taking over 100 cars off the road.

Conti designed and built this solar project to stand the test of time and completed it on budget, on schedule and just in time for the NFL season. At Conti, we have the same commitment to excellence of execution required for success in the NFL. The New York Jets demand the very best from themselves and from their partners, and Conti appreciated the opportunity to be a part of this stellar team.

This was the largest solar photovoltaic installation at a NFL team headquarters and another first-of-its-kind project successfully performed by Conti.

“Your crew was an absolute pleasure to work with throughout the project. The gang stayed focused even through heat that topped out well above 100 degrees where work conditions were borderline unbearable in order to come in ahead of the original schedule.” - Michael Lebet, Director, Building Operations

Beaver Run 9.9 MW Ground Array

Sayreville, NJ

Conti took over the struggling project, financed it and completed the EPC work within 3 months to meet tight deadlines.

Conti was able to take over a struggling project and bring it to on-time completion on an aggressive schedule by implementing a rare and innovative financing method.

The much-anticipated ground-mounted Beaver Run photovoltaic (PV) solar farm is situated on 36-acres of property in the town of Lafayette. Conti designed and constructed the 9.9 MW project in record time, achieving mechanical completion in less than two months. 1906 Group structured the acquisition of the project from the mid-stage developer and was heavily involved in successfully finishing the late stage development phase of the project.

The project qualifies for Solar Renewable Energy Credits (SRECs) as part of the state’s mandated Renewable Portfolio Standard and generates nearly 13 million kilowatt hours of clean electricity, enough to power approximately 1,500 homes in New Jersey per year.

Conti and 1906 Advisors arranged to finance the solar farm as a merchant facility, relying on short term SREC contracts and the project’s ability to sell power into the PJM Interconnection wholesale power market. The deal capitalized on the solar market swing, maximizing the near term value of solar attributes while keeping SREC upside value. Financial close was achieved in a record-breaking 60 days.

With the project completed, the Beaver Run solar PV array is interconnected to the Jersey Central Power and Light Company distribution system and transmits electricity to 1.1 million homes and businesses in 13 counties in central and northern New Jersey.

Conti financed, designed, constructed, owns, operates and maintains this renewable energy system.
