The US saw 156MW of utility-scale solar installed last month, up from 52MW in April, data from the country’s Federal Energy Regulatory Commission (FERC) reveals.
According to the Energy Infrastructure Update published every month by FERC’s Office of Energy Projects, solar was second only to wind in the amount of new capacity added in May.
Only five PV projects were completed in May, compared to nine in April, but the inclusion of the 99MW Imperial Valley Solar 1 project in California and 48MW Macho Springs project in New Mexico in this number pushed the total figure well above April’s.
The other three projects completed in May were Western Massachusetts Electric Co’s 4MW Indian Orchard Solar Facility in Hampden County, Massachusetts, the City of Lemoore’s 3MW City of Lemoore solar project in California and the 2MW Kearsarge Barre 1 solar project in Worcester County, Massachusetts.
The amount of utility-scale solar installed in the US in the first five months of this year is down on the same period in 2013 – from 1052MW to 907MW.
However, only 28MW of new PV capacity was added in May last year, yet the US went on to have a record breaking year, installing 3,897MW of new utility-scale capacity between January and December, up from 1,856MW in 2012.
Overall, utility-scale solar accounts for 0.75% of all installed generating capacity in the US, according to FERC.
