Commercial and utility scale solar electric facilities may well be the most scalable power plants for generating clean, renewable energy. However, integrating with existing infrastructure is often complex.
Browse the case studies below to learn more about some of the solutions we provide.
During the past eight years, Blue Oak Energy and REI have enjoyed a collaborative relationship resulting in over 25 solar installations at REI locations around the country, and a solar portfolio of 5.4 MW. Blue Oak Energy’s latest rooftop solar project for REI is located at the REI Distribution Center in Goodyear. This 2.2 MW solar system will account for 100% of the center’s annual energy consumption and bring the outdoor retailer closer to its solar energy goals.
Touro University Nevada is a non-profit institution established to address critical needs in health care education and to act as a resource for community service. The university pursued solar energy to eliminate a utility transformer upgrade while simultaneously reducing electricity costs.
This extensive 20MW solar farm project presented
unique challenges for our electrical and civil engineering teams due to the site’s rolling terrain and subtropical climate. By utilizing alternative engineering design software, Blue Oak Energy was able to achieve an accurate energy model that simulated energy production based on the varying degrees of solar array slope.
A 36MW ground mount utility-scale solar farm was developed across three distinct parcels. Approximately 28MW is located on the largest parcel, while nearly 8 MW is located on the two combined smaller parcels. This interesting project utilized two DC voltages in the solar array and utilized a variety of equipment across the site to meet the customer’s financial goals.
The Eastern Long Island Project (ELISP) is the largest combined carport installation in the state of New York with over 21 acres of solar panels installed across six different sites. The combined 12.8 MW photovoltaic (PV) system feeds power directly to local electric utility, The Long Island Power Authority (LIPA). Blue Oak Energy worked with a multidisciplinary team of engineering firms, contractors, and project stakeholders to meet various local and regional codes and standards.
From 2010-2012, 90MW was successfully deployed on 25 commercial solar rooftops in southern California. Part of the initiative includes the largest single solar PV rooftop in 2011 in the U.S., with a DC nameplate rating of 8.55 MW on a 1.3M square foot building.
Located at Brookhaven National Labs, the 37MW and 190 acre Long Island Solar Farm will feed power directly into the Long Island Power Authority (LIPA) utility grid. This system will power local businesses, neighborhoods and cities; in addition to helping LIPA meet its commitment for renewable energy production.
Blue Oak was 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. Blue Oak continues to operate and maintain this solar facility under a long term maintenance contract.
The Putah Creek Solar Farm is a distributed generation solar facility which was engineered and constructed by Blue Oak 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.
This extensive and architecturally complex campus required a forward-thinking design solution, including both rooftop and carport PV arrays.
Blue Oak Energy is the turnkey solar installer for REI's ambitious national multi-site solar initiative. We completed the engineering, procurement, and construction for 20 stores across seven states, which were selected based on multiple feasibility studies we performed for REI. Depending on any given location, a solar-equipped store will generate between 10 and 100 percent of its own electricity. The total capacity for the 20 stores is approximately 2 MW. The first round of this work started in 2008 with a total of seven stores and 675kW installed in California. The success from this initial program continues to lead to further feasibility studies and analysis with REI on their stores across the US.
The Fortinet Solar Campus project is a 908 kW net metered distributed generation solar photovoltaic system that covers two rooftops and three parking lots to power this corporate campus. We defined the project and proposed the ideal solutions to exceed the customer's expectations. This project was engineered and constructed by Blue Oak in 2014 and we continue to operate the solar facility to meet the intended financial returns.
The USVA Sacramento project focuses on increased energy savings through installation of a commercial solar rooftop and solar carport system. This system expands on the previously installed rooftop system by adding an acre of carport solar panels for a total of three acres of solar arrays, with a total expected output of 558 kW. The newly installed carport system is expected to generate approximately 832,000 kWh annually, while the rooftop system will generate 60,800 kWh. The solar carport system will also provide shade for vehicles and improved lighting at night. The entire solar generating facility will be interconnected and operate parallel to the Sacramento Municipal Utility District (SMUD).
The First Solar Mesa project is the largest rooftop installation in the state of Arizona with 18 acres of rooftop solar panels. The 4 MW photovoltaic (PV) system feeds power to First Solar’s Manufacturing Facility and exports excess generation to the local electric utility, Salt River Project (SRP).
