SAN DIEGO (AP) — A conservation group is challenging a proposed natural gas power plant in San Diego.
The state commission voted unanimously earlier this year to approve it despite concerns from environmentalists.
The plant's supporters say it is particularly needed because the San Onofre Nuclear power plant went offline last year.
Opponents say the approval undermines the state's commitment to green energy and will cost taxpayers $1.6 billion during its first 25 years.
The plant would be in Otay Mesa, about 20 miles southeast of downtown San Diego.
The CPUC says it hasn't seen the petition and can't comment.
