California Uses Battery Energy Storage Instead Of Gas-fired Power Generation

May 17, 2018

According to Mining Weekly quoted from Bloomberg News, California, with its battery-powered electric car boom, is launching another similar public-equipment revolution that could cause trouble for all gas-fired power plants in the United States.

On January 11, the California Public Utilities Commission authorized the state's largest utility company, PG&E Corp., to change its peak power supply. To get rid of the complete reliance on the three gas-fired power plants operated by Calpine Corp., PG&E must use batteries or other non-fuel resources to ensure the lighting needs of the most densely populated states in the United States.

This shift is possible in California, partly due to excess solar energy. Over the past 10 years, with the development of rooftop solar panels and large-scale acquisition systems, the use of renewable energy in California has doubled. The battery can be charged during the day and then discharged. With technological development and cost reductions, energy storage systems for public facilities have become more feasible, especially in California, where it plans to increase wind power generation to 50% by 2030 to reduce greenhouse gas emissions.

S&P Global Ratings Michael Ferguson, head of U.S. energy facilities research, said that California is drawing a blueprint for the next few years. The state has a large population, abundant renewable energy, lower electricity costs, and battery storage. such.

The U.S. government has been seeking ways to reduce carbon emissions to control global warming and climate change. Two years ago, clean and cheap natural gas became the main source of U.S. electricity generation. According to data from the U.S. government, natural gas power generation now accounts for one-third of total U.S. electricity production. However, the development of solar and wind power is faster. Compared with 10 years ago, its share in 2017 has risen to 17%.
