Citing costs, stakeholders eye changes to Cal-ISO Aliso plan

摘要

Stakeholders are seeking revisions to the California Independent System Operator’s plan to address ongoing limitations of the Aliso Canyon gas storage facility, with some parties claiming key measures have already significantly increased costs in the Cal-ISO market. Meanwhile, NRG Power Marketing is arguing that tight market conditions this past summer show why the US Federal Energy Regulatory Commission should require tweaks to the proposal to ensure plant dispatch better reflects high gas prices. “While the current CAISO tariff allows NRG to file to recover gas procurement costs that cannot be covered in the CAISO’s energy markets, all parties have a direct interest in reducing the likelihood [of] these extraordinary cost-of-service measures,” NRG said in a protest posted by FERC Tuesday.
