Ameresco to install 5-MW solar, 11.6-MWh storage project for U.S. Coast Guard

Ameresco has been contracted by the US Coast Guard to install a solar energy + storage system at the Coast Guard’s largest training facility on the West Coast, Training Center (TRACEN) Petaluma. This will be the Coast Guard’s first battery project and the Department of Homeland Security’s largest solar project.

Proposed project

TRACING Petaluma faces a range of energy security and resilience challenges that are endemic to the climate and regional energy infrastructure in Northern California. In light of the regularity and severity of weather conditions and power outages affecting the site, the Coast Guard competitively selected Ameresco in February 2021 to accelerate the development of a comprehensive energy-saving performance contract to improve the site’s electrical infrastructure and resilience.

The microgrid will integrate existing distributed backup generators with a new 5 MW solar panel and 11.6 MWh energy storage system to power the entire site in the event of a power outage. Planned improvements also include deployment of new power distribution transformers, smart controls in 10 campus buildings, improvements to LED lighting for more than 8,000 fixtures, installation of new electric vehicle charging infrastructure, and upgrades to heating, ventilation and air conditioning (HVAC) equipment .

“This contract award will enable continuity of operations in an environment of unpredictable climate hazards and will increase the relevance of Training Center Petaluma across the region while preserving our total Coast Guard mission staffing level,” said Captain Steven Ramassini, Commander of the Coast Guard. the training campus. .

“To meet the evolving needs of the Coast Guard, we need to look beyond just using traditional direct credit. The use of energy performance contracts enables the Coast Guard to address critical infrastructure improvements in a time frame that would not be feasible with conventional methods and provides holistic solutions to complex problems. By leveraging partnerships and finding unique solutions, the Coast Guard is able to deliver mission-critical improvements with our limited resources,” noted Rear Admiral Carola List, Deputy Commander of Engineering and Logistics, and Chief Engineer of the Coast Guard.

Once completed, Training Center Petaluma will realize cost savings of more than $1.2 million in its first year alone. The project will also reduce the site’s annual electricity and propane consumption by 8.7 million kWh and 50.8 kgal, respectively.

“We are so honored to lead the design and development of this historic project for the United States Coast Guard,” said Nicole Bulgarino, executive vice president, Ameresco. “The outlined upgrades integrate energy efficiency and clean energy on site with advanced microgrid controls and significantly improve the energy resilience of the training facility. The completed project will set a strong precedent for future federal renewable generation and battery storage projects.”

Construction on the project will begin in October 2021 and will be completed in the fall of 2023.
