Cal-ISO aims to ease Powerex EIM limitations caused by market power mitigation

摘要

Powerex’s participation in the Western Energy Imbalance Market has been limited by an unexpected result of the way the California Independent System Operator mitigates potential market power. Powerex, BC Hydro’s trading arm, is starting participating in the EIM on April 4, but is limiting its exports into the market to avoid being forced to sell at a bid price that doesn’t reflect its opportunity costs, Cal-ISO said in a waiver request filed Tuesday at FERC (ER18-1339).
