Utilities

 

Utility solar has long been—and remains—the largest driver of the solar market and the biggest promise of making a clean energy future a reality. With more than 10 GW expected to come online in 2016, that’s not likely to change soon. A number of factors are driving utility solar's continued growth.

  • States strengthening their renewable portfolio standard (RPS) requirements
  • Utilities’ voluntary procurement of solar beyond RPS requirements
  • Solar’s cost-competitive economics, including solar’s predictable, low-cost Opex vs. fossil fuel price volatility
  • Growing pressure and regulatory requirements to reduce the carbon intensity of utility generating fleets
  • Solar’s strong appeal with customers

Green Acres

  • Elk Grove, CA
  • 5 MWp (4 MWac)
  • Sacramento Municipal Utility District (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. 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.

  • Pacific Gas & Electric (PG&E)

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.
