California needs to deploy 40GW long-term energy storage system to achieve the goal of carbon-free electricity by 2045

The California State Energy Regulatory Agency recently stated that the state will deploy a long-term energy storage system with an installed capacity of 1GW by 2026. But so far, there are not many users of energy storage technology that can meet this demand cost-effectively. This situation is now changing. The California Community Choice Aggregator (CCA) recently announced an offer to purchase an installed capacity of 500MW of long-term energy storage capacity. As a result, they appealed to the California Public Utilities Commission to invest in long-term energy storage resources. California Community Choice Aggregator (CCA) is an alliance of 8 California Community Choice Aggregators led by Silicon Valley Clean Energy Corporation (SVCE). Girish Balachandran, CEO of Silicon Valley Clean Energy Corporation (SVCE), said in an interview: 'We know that long-term energy storage systems are the energy storage resources we need in the future. As a load service entity, we will take the first step forward. 'In fact, the California Community Choice Aggregator (CCA) signed the largest long-term energy storage deployment contract in the United States so far. JinNoh, senior policy manager of the California Energy Storage Alliance, said: 'This contract will enable the U.S. long-term energy storage market to be further developed.' By 2026, the continuous discharge time will reach 8 hours or more. Currently deployed on a gigawatt scale. The continuous discharge time of a lithium battery energy storage system is usually only 4 hours. When continuing to add continuous discharge, its cost will rise exponentially. However, many power grid analysts believe that with the surge in wind and solar power generation, cheap long-term energy storage systems will play an important role and transform intermittent power generation from renewable energy sources into all-weather power generation resources. The energy storage industry has not clarified the meaning of long-term energy storage. And some energy storage startups call their 4-hour energy storage system long-term energy storage system. For example, the Cambridge-based start-up company FormEnergy has a contract for an energy storage facility with a continuous discharge time of up to 150 hours in Minnesota this year. According to the contract signed by the California Community Choice Aggregator (CCA), the long-term energy storage project that meets its deployment conditions must have an installed capacity of more than 50MW, a continuous discharge time of at least 8 hours, and must be opened for operation before 2026. The reason for the bidding is to open up operations faster. Its opening date seems to be far away. However, most long-term energy storage companies are either adopting new technologies or capital-intensive construction projects (such as pumped storage facilities). Silicon Valley Clean Energy Corporation (SVCE) Power Resources Director Monica Padilla said that the development of such projects usually takes several years of preparation time. Regarding the long-term energy storage industry, six years of its solid development is still a big step forward. The industry has been struggling to find customers who are willing to deploy long-term energy storage systems. Noh said: 'The 2026 deadline will help bring some urgency. This will help provide overall support for this segment.' Earlier this year, many energy storage developers requested for this offer. There was a response, but the names of these companies were not disclosed. Silicon Valley Clean Energy Corporation (SVCE) confirmed these responses. These energy storage technologies include energy storage technologies such as lithium batteries, flow batteries, compressed air, and pumped storage facilities, as well as emerging energy storage technologies such as thermal energy storage and gravity energy storage. technology. Padilla pointed out that the California Community Choice Aggregator (CCA) will act as a dispatch coordinator to determine what the energy storage system is charging and discharging, which provides a certain degree of freedom in what role the long-term energy storage bid winner will play. These projects will provide early on-site verification of the value that long-term energy storage assets can provide. Obtaining such data is necessary because California may invest more in such resources. A study conducted by the research organization Strategen Consulting found that to achieve California's goal of achieving carbon-free electricity by 2045, a long-term energy storage system with an installed capacity of 40GW must be deployed. California needs to deploy a 40GW long-term energy storage system to achieve the goal of carbon-free electricity by 2045.
