California ISO Declares Stage Two Emergency; Power Usage High and Trending for Another Record Peak Demand.FOLSOM, Calif. -- The California Independent System Operator Corporation (California ISO (1) See ISO speed.

At that time participants of the California ISO Voluntary Load Reduction Program were notified to implement voluntary conservation measures. Today's peak power demand on the transmission system is expected to reach 52,000 megawatts around 4:00 p.m. Thus far today, electricity demand is trending nearly 3,000 megawatts over the record demand of 49,036 experienced last Friday, July 21. Additional conservation remains critical throughout today if the ISO and the state's utilities are to continue meeting the entire power demand. If Californians do not step up their conservation efforts this afternoon considerably, a Stage Three Emergency and rotating outages are possible. Today's Stage One and Two declarations, in effect until 11:00 p.m., enable the California ISO to access emergency resources to help maintain operating reserves. The California ISO is a not-for-profit public benefit corporation charged with managing the flow of electricity along California's open-market wholesale power grid. The mission of the California ISO is to safeguard the reliable delivery of electricity, and ensure equal access to 25,000 circuit miles of "electron highway." As the impartial Favoring neither; disinterested; treating all alike; unbiased; equitable, fair, and just. operator of the wholesale power grid in the state, the California ISO conducts a small portion of the bulk power markets. These markets are used to allocate space on the transmission lines, maintain operating reserves and match supply with demand in real time.
