More than 650GW to be connected to the grid! Many U.S. solar projects enter  an ice age

　　According to an analysis by Lawrence Berkeley National Laboratory (LBNL),  nearly 1TW (1,000GW) of renewable energy and 427GW of expected energy storage  capacity are in ice age by the end of 2021, and they remain in the  grid-connected queue in the United States. At the same time, the team is still  growing year by year.

　　Overall, there is currently more than 930GW of zero-carbon electricity  expected to be integrated into the transmission grid. Of this, 676GW of solar  was a new record, with 462GW at the end of 2020. Wind power is 247GW. On the  other hand, fossil fuels looking to connect to the grid are declining, with gas  currently at 75GW and coal at less than 1GW.

　　Solar and battery storage have been the fastest growing of this group so  far, accounting for 85% of new grid-connected capacity in 2021, but some  projects have the lowest completion rates, LBNL said. Clean energy groups have  been calling for changes to the system to push more solar and energy storage  into the grid. In fact, nearly half of the battery storage capacity in the queue  is paired with some form of power generation, mostly solar.

　　However, most of these planned capacity projects never ended up being  built, and according to LBNL analysis, from 2000 to 2016, only 23% of projects  committed to grid connection and subsequent construction in time. For example,  only power system operators ISO-NE and the Texas Electric Reliability Commission  have completion rates above 30 percent, and California independent system  operators are the worst performers at 13 percent.

　　LBNL found that the wait time to connect to the grid is also growing. In  regions where data are available, the typical time from grid connection  application to commercial operation increased from about 2.1 years in 2000-2010  to about 3.7 years in 2011-2021.

　　In February, a coalition of three clean energy industry associations called  for the Federal Energy Regulatory Commission (FERC) to make grid-connection  reform a top priority to reduce the backlog of projects waiting to be integrated  into the national grid. "The backlog of projects waiting to be connected to the  grid is one of the biggest barriers to quickly and effectively decarbonizing the  grid in the near term," said Sean Gallagher, SEIA's vice president for state and  regulatory affairs.

　　In addition, LBNL said the "percentage completion" of projects seeking to  connect to the grid appears to be declining, with wind and solar even lower than  other forms of energy. LBNL analyzed grid-connected project data from seven  transmission system operators and California Independent System Operators  (ISO/RTOs), as well as 35 non-ISO utilities, representing more than 85 percent  of total U.S. electricity load.webcam factory

　　In the US, transmission system operators (ISO, RTO or utility companies)  require that projects wishing to be connected to the grid need to carry out a  series of impact studies before construction. LBNL said that most projects that  applied for grid connection were eventually withdrawn, and completed projects  took on average longer to complete the required studies and put them into  operation.

　　Although SES Power is a manufacturer that designs and manufactures  customized lithium-ion batteries, our products, such as 12V100Ah, 12V200Ah,  24V100Ah, 24V200Ah, 36V100Ah, 48V50Ah, 48V100Ah, which use square aluminum-shell  lithium iron phosphate batteries, are equipped with high-performance 12V30Ah,  12V50Ah, 12V60Ah car starter batteries (maximum peak current up to 1500A) of  multi-rate lithium batteries are often used in conjunction with photovoltaic  power generation and energy storage systems, so we also hope that the clean  energy industry, especially photovoltaic power generation, can get real  advancement.
