As a heat wave continues to roast the Southland, the Los Angeles Department of Water and Power asks customers to keep conserving energy use where possible between 11:00 a.m. and 6:00 p.m. today, while staying safe. A statewide Flex Alert was issued yesterday by the California Independent System Operator (CAL ISO) to encourage energy conservation through Sunday, August 12. LADWP joins CAL ISO in this call, asking customers for conservation to prevent overtaxing the electrical infrastructure that serves Los Angeles around the clock daily.

Energy demand in Los Angeles reached 5642 megawatts Thursday but today’s demand is expected to approach higher levels, as the heat wave reaches its peak intensity, with temperatures exceeding 100 degrees for the fourth straight day in the San Fernando Valley. LADWP’s all-time high energy demand was 6177 megawatts, recorded on September 29, 2010.

Heat-Related Power Outages

Despite the high temperatures, the LADWP system has functioned well and power outages have been minimal, however hot weather can lead to outages- and for a variety of reasons. The heat not only leads to more people operating their air conditioners all at once but also causes other appliances to work harder in order to perform. This puts strain and stress on electrical infrastructure and can overburden power lines, transformers and other equipment, causing them to fail. It can also trigger substation circuit breakers or other electrical equipment that is designed to protect the system to shut down automatically before serious damage occurs.

Energy Conservation Tips

To help reduce energy use, LADWP recommends the following as highly effective conservation measures:

  • Adjust thermostat to 78 degrees to reduce energy usage during the hottest hours of the day when air conditioning systems have to work hardest to cool.
  • Limit the use of appliances during peak hours of the day- use washing machines, dishwashers, vacuum cleaners and other heavy appliances during evening hours.
  • Close draperies, shades or blinds during the heat of the day to reduce the extra heat from direct sunlight.
  • Ventilate your home by opening windows and doors to clear out the heat and allow cooler air to circulate.
  • Turn off lights and equipment when they are not in use.
  • Unplug “energy vampires” like cell phone chargers, DVD players, microwave ovens and other appliances that use energy even when turned off or in sleep mode.

LADWP on Tuesday issued these tips to help conserve energy and stay cool at home and in the workplace.

The City of Los Angeles Emergency Management Department (EMD) recommends the following during periods of extreme heat, to avoid heat exhaustion, heat cramps and sunstroke:

  • Drink plenty of water; don’t wait until you are thirsty.
  • Wear light, loose-fitting clothing.
  • Avoid unnecessary sun exposure; wear a hat, preferably with a wide brim, when in the sun and use sunscreen.
  • Avoid unnecessary physical exertion if you are outside or in non-air conditioned buildings. If you are working outdoors, take frequent rest and refreshment breaks in a shaded area.
  • Never leave children, elderly people or pets unattended in closed cars or other vehicles.
  • Check on those who are at high risk to make sure they are staying cool – including seniors who live alone, people with heart or lung disease, and young children.
  • Stay cool indoors – if your home is not air conditioned, visit public facilities such as shopping malls and libraries to stay cool.
