Highlighted utility scale project:

Putah Creek, Yolo County, CA

Project: Putah Creek
Location: Yolo County, CA
System Size: 2.6 MW

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.

Gridley Solar Generation Facility, Gridley, CA

Project: Gridley Solar Generation Facility
Location: Gridley, CA
System Size: 4.2 MW
Utility Company: Northern California Power Agency (NCPA)

The Gridley Solar Farm was designed and constructed by Blue Oak Energy in 2012. The electricity generated by the 25 acre Gridley solar facility 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.

Confidential Site, Nevada Solar Facility

Project: Confidential Site, Nevada
Location: North Las Vegas, NV
System Size: 20MWac
Utility Company: NV Energy

This is a utility scale Solar PV project located just north of Las Vegas. Blue Oak Energy completed the Electrical and Structural Engineering, as well as on-site value engineering services. The site is positioned in a large watershed received by a nearby mountain range. The continuity between Blue Oak Energy's electrical and civil engineering design coordination and stormwater planning was critical early-on for the project's ultimate success. The preliminary engineering for this project started in 2012 and was completed in 2013.

Shasta Solar Farm

Project: Shasta Solar Farm
Location: Fall River Mills, CA
System Size: 4.4MWp (3.0MWac or 1.5MWac per interconnection)
Utility Company: PG&E

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.

Green Acres solar project

Project: Green Acres
Location: Elk Grove, CA
System Size: 5.0MWp (4.0MWac)
Utility Company: SMUD

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. Blue Oak 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.

Cascade solar project

Project: Cascade
Location: San Bernardino County, CA
System Size: 24.5MWp (18.5MWac)
Utility Company: SCE

The Cascade Solar project is located north of Joshua Tree National Park in unincorporated San Bernardino County, California. Blue Oak Energy was hired to complete the full civil, structural, and electrical engineering, and manage the grading and building permit approval process. We coordinated very closely with the county planning and permitting offices to ensure the project met the county requirements while expediting the permit communications to achieve project commercial operation on schedule.

Gillespie solar project

Project: Gillespie
Location: Maricopa County, AZ
System Size: 20.2MWp (16.0MWac)
Utility Company: APS

Blue Oak Energy delivered the Electrical, Civil, and Structural Engineering while also designing in dynamic power curtailment and power factor control capability to meet APS standards for future grid functionality. The Gillespie Solar Generating Facility tracking system utilizes an inverter plant controller capable of curtailing the 16MWac inverter system to 15MWac per utility requirements, while also maximizing the plant output during low-production times to maximize client ROI and energy production to APS.

Horn Solar Facilities Ma Solar Facilities

Project: Horn and Ma Solar Facilities
Location: Lancaster, CA
System Size: 4.1MWp (1.5MWac per interconnection)
Utility Company: SCE

Blue Oak provided the full scope Civil and 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.

Long Island Solar Farm, Brookhaven National Labs, New York

Project: Long Island Solar Farm
Location: Brookhaven National Lab, Upton, NY
System Size: 37 MW
Utility Company: Long Island Power Authority (LIPA)

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.

Five Points Solar Facility, Five Points CA

Project: Five Points
Location: Five Points, CA
System Size: 18 MW
Utility Company: Pacific Gas & Electric

The 15-MW project is part of PG&E's 250-MW Utility Owned Generation (UOG) PV Program. Blue Oak Energy engineers employed the SOLON standard block sizing and innovative wire management to maintain a low cost, high efficiency installation.

Southern California Edison and ProLogis Southern California Edison and ProLogis Southern California Edison and ProLogis Southern California Edison and ProLogis Southern California Edison and ProLogis Southern California Edison and ProLogis Southern California Edison and ProLogis

Project: Southern California Edison and ProLogis
Location: Southern California
System Size: 90 MW Aggregate
Utility Company: Southern California Edison (SCE)

From 2010-2012, 90MW was successfully deployed on 25 commercial rooftops in southern California. Part of the initiative includes the largest single solar PV rooftop in 2011 in the US, with DC nameplate rating of 8.55MW on a 1.3M square ft. building.

West Tennessee Solar Farm

Project: West Tennessee Solar Farm
Location: Stanton, TN
System Size: 5.1 MW
Utility Company: Tennessee Valley Authority

The 25-acre farm is the largest solar generation facility in the state of Tennessee and still one of the largest in the country. This material is based upon work supported by the Department of Energy under Award Number DE-EE0000160. Funding Source: CDFA 81.041.

Haverhill Solar Project

Project: Haverhill Solar Project
Location: Haverhill, MA
System Size: 1 MW
Utility Company: National Grid

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.

Stanton Solar Farm

Project: Stanton Solar Farm
Location: Orange County Florida
System Size: 5.9 MW
Utility Company: Orlando Utility Commission (OUC)

This is the first solar farm in this county, which is located at the Orlando Utility Commission's Curtis H. Stanton Energy Center. The solar farm contains over 25,000 solar modules, mounted on single-axis trackers prominently visible from Innovation Way.

We've also partnered with public sector and corporations to design, engineer, and build large-scale photovoltaic solar systems.
