Detailing how it will comply with Order 1000, the California Independent System Operator Corp. submitted a compliance filing to the Federal Energy Regulatory Commission October 11 proposing few changes to current rules for building new transmission line and asserting that reforms to increase renewable energy generation have been made over the past two years. The operator’s changes would be effective October 1, 2013. The four remaining regional grid operators have requested more time to make their filings; in response, the commission has extended their filing deadline to October 25.
