For five days in November 2010, San Juan County experienced a cold snap with an average daily temperature of only 25 degrees.  OPALCO members are going to notice the difference on their power bills that go out at the end of the month. “When temperatures drop below 50 degrees,” explained OPALCO System Engineer Joel Mietzner, “we see electrical usage go up as members use more energy to maintain a comfortable indoor temperature.”

Power purchases for the five day period added up to 6,826,980 kWh as compared to 3,274,460 kWh for the same five-day period in 2009 when the average temperature was 45 degrees. The rest of November was comparable to last year in terms of temperature and power purchases. “Load growth is steady at less than one percent,” said Mietzner, “it’s the temperature that contributed to higher bills this billing cycle.”

A good first step in protecting your household from higher energy bills is to have a Home Snapshot Energy Assessment through OPALCO. A certified contractor will inspect your home from top to bottom and leave you with a detailed report on areas where you could see savings—in kWh and dollars—with energy efficiency improvements. Once you discover how your home could benefit from some energy efficiency upgrades, OPALCO can also help with the cost of making improvements. “Weatherization rebates are available for insulation, window replacement and duct sealing,” said Energy Services Assistant Manager Anne Bertino. “And, federal rebates are continuing into 2011. Now is a good time to take advantage of all of the incentives and start seeing the savings on your energy bill.”
