This utility-scale solar facility is constructed in a 100-year FEMA floodplain and therefore required some special design considerations from our civil, structural and electrical engineering staff. We acted as the full service civil, structural, and electrical engineer for the project which is spread across 2 distinct parcels of property. We worked closely with the installing contractor and the utility to meet some stringent interconnection requirements.
The ground mounted system is capable of generating enough electricity for about 1,200 average-sized homes.
We were engaged to design and construct this solar facility on a tight schedule. We engineered the full project, obtained construction permits, and coordinated two separate interconnections with the utility company. The local distribution grid had some special needs and therefore we worked with the utility company to provide special inverter system ramp-rates and reactive power controls. This single-axis tracker system was designed to eliminate any grading at the site and therefore has minimal impact on this unique site's location. We continue to operate and maintain this solar facility under a long-term maintenance contract.
We designed and constructed the Gridley Solar Facility in 2012. The electricity generated by the 25-acre project is directed to the City of Gridley and the Bay Area Rapid Transit (BART). Engineering and permitting was accomplished in nearly 8 weeks and construction was completed in approximately 18 weeks.
We provided the full scope civil, structural, and electrical engineering for the long-term system investor and owner. Our scope also included preparing the Storm Water Pollution Prevention Plan (SWPPP) and Dust Control plans and negotiating for the final construction permits. Our services also included assistance with bidding the project out for construction and providing construction phase engineering support to assist an aggressive commercial operation schedule.
The Putah Creek Solar Farm is a distributed generation solar facility which we engineered and constructed in 2014. This is one of the first Electric-Renewable Market Adjusting Tariff (E-REMAT) program solar facilities to be installed on the California Independent System Operator (CAISO) controlled electrical grid. We co-developed the project and proposed the ideal solutions to fully permit and construct this solar farm while also maximizing the project's financial returns.
Located on a former manufactured gas storage facility, this system now offsets the emissions produced in generating electricity for 200 homes. A unique design component was utilizing the eastward slope of the available land to maximize the PV system size.
This single-axis tracking system provides a 12% increase in production over traditional fixed-rack systems, covering 23% of the Mariani plant’s entire electrical needs.
Distributed across 22 separate Authority facilities, this 707 kW project was financed using a 20-year Power Purchase Agreement (PPA) with the Authority. Electricity generation for the first full year of service is projected at 1,013,500 kWh.
This program was part of the 2009 American Recovery and Reinvestment Act (ARRA). The goal of the project was to modernize existing naval facilities throughout the Southeast and Mid-Atlantic region with grid-tied photovoltaic systems.
The U.S. Department of Energy commissioned this single-axis tracker array for use at National Renewable Energy Laboratory. This was part of the Transformation Energy Action Management (TEAM) initiative for on-site renewable electricity generation.
This unique facility for the City of San Diego includes a ground-mounted array as well as arrays built upon two storage tanks. This deployment for the City of San Diego is part of the city's plan to deploy 5 MW of solar capacity.
At time of completion this facility offset 90% of the District's power needs. Engineering challenges included sensitive wetlands area, as well as developing a foundation solution for the 2-acres of bay mud.
The aging electrical infrastructure at this site provided some interesting challenges for the Port of Oakland's first photovoltaic system. However, with the help of the Port's dedicated facilities team, the project was successfully completed.
This solar energy project reduced the Federal Government Service Administration's energy consumption by more than 1,600 MWh per year; this is equivalent to powering 145 homes in Colorado.
These two projects—Chuckawalla Valley and Ironwood—were part of the California Department of General Services distributed generation initiative. These solar arrays are separated by some distance, but connect into the same electrical distribution feeder.
The solar installation is located in the heart of the 220-acre CU Research Park, home to the Laboratory for Atmospheric and Space Physics (LASP), Center for Astrophysics and Space Astronomy (CASA), and the Jennie Smoly Caruthers Biotechnology Building. The array is a ground-mount installation that will provide clean energy power generation to both research facilities and buildings throughout the Boulder campus.
This is the largest solar energy system to be installed on a college campus to date. The array was designed to accommodate the existing uneven topography of the site without having to perform extensive grading.
Engineering plans for this project were completed in only two weeks. Close coordination by a cross-disciplinary team of geotechnical, structural, civil, and electrical professionals enabled us to provide a solution for this complex site.
At commissioning, this solar facility supplied 80% of the college's energy needs. A new ballasted racking system, along with ideal site conditions, facilitated the completion of the project in record time.
