Puget Sound Energy (PSE) is encouraging its more than 1.1 million electric customers to be even more energy conscious as temperatures jump into the high 80s or even 90s over the next several days.
Across its service area, PSE’s electric infrastructure is performing well, and its generating facilities have the capacity to meet the needs of customers, according to a PSE media release. While excessive heat puts extra demands on the power grid, the region uses more energy on cold winter days than it will during this heat wave.
Over the years, PSE has seen more power consumption during the summertime as customers add some form of air conditioning in their homes; it’s estimated about 11 percent of PSE residential electric customers have AC.
Because of that growth, energy conservation is even more important right now. PSE plans for peak customer usage by constantly monitoring the health of its system and investing in infrastructure projects to keep the system redundant and reliable.
PSE’s one-hour summer record for power usage was set on July 27, 2009. As temperatures reached into the 100s, 3,430 megawatt-hours (MWh) of electricity was used between 7-8 p.m. By comparison, PSE customers’ all-time, one-hour high for power usage was 4,906 MWh set on Dec. 15, 2008 during a major cold weather event.
WHAT CUSTOMERS CAN DO TO SAVE ENERGY IN THE DAYS AHEAD
• Set your thermostat as high as comfortably possible. For those with central air or air conditioning, PSE recommends no lower than 75 degrees. That might seem on the warm side, but customers can save up to 5 percent on their electric bill by taking that simple step.
• Invest in a programmable thermostat that will automatically adjust the indoor temperature while you’re away.
• Use fans to help circulate the air. Remember that ceiling fans cool you, not the room, so when you leave the room, make sure to turn off the fan.
• Make sure to close window blinds and curtains to block direct sunlight. In the evening, open windows for cross ventilation.
• Switch out any conventional light bulbs with LED or compact fluorescent light bulbs, which produce 70 percent less heat.
• Run appliances – such as dishwashers, clothes washers and dryers – at night. A hot dishwasher sends heat throughout the house; run only on full loads and use the ‘no heat’ option for the drying cycle.
• Consider cooking a later dinner or grilling outside to prevent any additional heat buildup.
