Investor-owned utility SDG&E and the City of San Diego are launching a dozen microgrid projects with energy storage across San Diego, CA.

Investor-owned utility SDG&E and the City of San Diego are launching a dozen microgrid projects with energy storage across San Diego, California, following similar announcements elsewhere in the state.

San Diego Gas & Electric (SDG&E) received approval on June 24 from the California Public Utilities Commission (CPUC) to build four microgrid projects at existing substations in the San Diego region, with a combined 39MW/180MWh of energy storage capacity.

The units will help the state of California meet high energy demand, particularly on hot summer days and during peak demand evening hours when solar generation is low. They will be able to operate independently or in parallel with the larger regional grid ensuring critical community facilities remain powered during grid-level outages.

The Department of the Interior has issued final approval for construction of the Arica and Victory Pass solar projects near Desert Center in eastern Riverside County.

PALM SPRINGS, Calif. — The Department of the Interior has issued final approval for construction of the Arica and Victory Pass solar projects near Desert Center in eastern Riverside County, a significant milestone in the Biden-Harris administration’s efforts to modernize America’s power infrastructure in the West and permit at least 25 gigawatts of solar, wind and geothermal production on public lands by 2025.

“The efficient deployment of renewable energy projects is crucial to lower costs for families, support good paying jobs, and achieve the Biden-Harris administration’s goal of a carbon pollution-free power sector by 2035,” said Laura Daniel-Davis, Principal Deputy Assistant Secretary for Land and Minerals Management. “Combined with the historic investments from President Biden’s Bipartisan Infrastructure Law, we will continue to work in partnership with states, cities and Tribes to boost climate resiliency, advance clean energy projects, and replace aging infrastructure.”

Microsoft has signed a new Power Purchase Agreement (PPA) with AES to procure renewable energy for its Californian facilities.

AES Corporation this week announced a 20-year agreement with Microsoft to provide renewable energy to its data centers in California.

In what AES called a “highly customized agreement,” Microsoft will partially match its load at their California-based data centers. AES will source the energy from a portfolio of 110MWAC solar and 55MW, 4-hour storage projects in the California Independent System Operator (CAISO) region.

America’s electric power system is undergoing radical change as it transitions from fossil fuels to renewable energy. While the first decade of the 2000s saw huge growth in natural gas generation, and the 2010s were the decade of wind and solar, early signs suggest the innovation of the 2020s may be a boom in “hybrid” power plants.

A typical hybrid power plant combines electricity generation with battery storage at the same location. That often means a solar or wind farm paired with large-scale batteries. Working together, solar panels and battery storage can generate renewable power when solar energy is at its peak during the day and then release it as needed after the sun goes down.

US electricity generation from renewable sources will increase to 23% in 2023 from 20% last year, as solar and wind begin to erode the leading market share of natural gas, according to a new report from the Energy Information Administration (EIA).

That shift, if lasting, would end the steady market gains of natural gas that began in 2014, enabling it to surpass coal two years later as the leading generation source in the world’s largest electricity market. Renewables will take 22% of the US power market this year.

PG&E announced that they have turned on their giant Tesla Megapack project with 730 MWh of capacity, and the electric grid company expects that it will “enhance the overall reliability of California’s ever-changing energy supply.”

We first learned of the project at PG&E’s Moss Landing substation when it submitted it to CPUC and the company was in talks with Tesla in 2017. It involves four separate energy storage projects, and two of them, including the one using Tesla Megapack, should become the world’s largest battery systems.
