 PGE Corp. said its California customers can expect to suffer power outages Tuesday that could last about two hours, as a result of the Flex Alert announced by the California Independent System Operator CAISO, which manages the states power grid. The San Francisco-based utility said rotating outages are necessary under the Flex Alert, which is in response to forecasts of extended, above-normal temperatures across the state, that is expected to put a strain on the states grid. During these emergencies, the CAISO will typically order the states utilities, including PGE, to reduce electric load by turning off service immediately to prevent larger outages on the grid, PGE said in a statement. These outages are not Public Safety Power Shutoffs, which are called during specific high fire-threat conditions, and they are not related to any issues with PGEs equipment or its ability to deliver energy locally. The stock, which rose 2.0 in afternoon trading, has dropped 14.0 year to date, while the SPDR Utilities Select Sector ETF has slipped 6.9 and the SP 500 has gained 5.0.
