Heat wave spawns Flex Alert
SACRAMENTO – (INT) – Californians were hit with their first Flex Alert of the year Tuesday as searing heat baked much of the state.
The call for conservation of electricity by the California Independent System Operator Corporation (ISO) covered 6-hours when air conditioners were at their peak use.
ISO anticipated energy demand reaching a peak of 42,800 megawatts (MW). Also, two units with a total generation of 1,260 MW were offline due to mechanical failures. The Flex Alert was called in response to the high electricity demand and reduced generation.
Earlier Tuesday, ISO issued a Restricted Maintenance Operations (RMO), which requires generators and transmission owners to postpone scheduled maintenance, to keep grid assets available for use.
Temperatures are showing signs of cooling and additional Flex Alerts were not expected the rest of the week.
