Statistically Speaking, the Real Heat is on its Way for Richmond

Thursday, July 8th, 2010

FROM RICHMOND TIMES-DISPATCHRichmond, Va. — After three straight days of triple-digit temperatures, here’s a warming thought: Richmond’s traditionally hottest stretch is yet to come.

The second half of July is, on average, the region’s warmest spell, and early August can be brutal, too.

“I won’t say we will continue to have a heat wave, but we’ve got plenty of hot weather to go,” said James Foster, a National Weather Service meteorologist.

The high temperature in Richmond yesterday hit 104, which broke the record of 103 set in 1977. That followed highs of 103 on Tuesday and 100 on Monday.

The heat has been linked to at least three deaths across the state. It has dried lawns, lowered streams, raised concerns about possible water restrictions, and turned lunch-time power walkers into indoor wimps.

“I am so-o-o hot,” said Sadie Williams, 8, of Short Pump as she visited Brown’s Island in Richmond yesterday with her father and two sisters. “Sometimes, the second I get into my car, I start sweating.”

Richmond’s torrid June and July have produced six days so far that reached 100 or hotter. The record for 100-degree-plus days in a year here is nine in 1954.

Virginia is not yet in a drought, but most of the state, including central Virginia, is abnormally dry, according to the U.S. Drought Monitor, a weekly report by federal and academic scientists.

Richmond and the counties of Chesterfield, Hanover and Henrico are considering asking people to conserve water if the dry weather continues. Requests could come as early as next week.

“However, a strong thunderstorm or two can push that time out,” said Arthur D. Petrini, Henrico’s utilities director. “It’s still a little early to predict.”  Gov. Bob McDonnell warned Virginians that the dry conditions make the state ripe for wildfires.

“Something as seemingly benign as parking your car or truck on a patch of dry grass could result in a fire that burns hundreds of acres of field or forest,” McDonnell said.

Ozone, the main pollutant in smog, hit the Code Orange level yesterday and marked Richmond’s fourth straight day of unhealthful air.  Before this week, ozone had not hit unsafe levels since September 2008. Ozone should be in the safe zone today.

Levels of tiny airborne particles such as soot and dust were high yesterday, which created a whitish haze across the region.

Dan Salkovitz, a meteorologist with the state Department of Environmental Quality, said the pollution may have been produced by, among other things, coal-burning power plants that were working hard to produce electricity during the heat wave.

That heat wave should recede slightly today and tomorrow as cooler air moves into the region and drops temperatures into the mid-90s, the weather service said.

That air will be more moist, so “it might feel a little more muggy,” said Tim Gingrich, a weather service meteorologist.

Beyond that, the forecast calls for a cold front to move through the area tomorrow night and Saturday. That should drop the temperature to about 90 on Saturday and might even cause some rain.

Forecasters expect highs in the low 90s on Sunday and early next week.

East Coast Heat Wave Puts Stress on Power Grids: Virginia No Exception

Thursday, July 8th, 2010

FROM THE TIMES DISPATCH, Richmond, Va. — The eastern United States cooked for another day yesterday as unrelenting heat again sent thermometers past 100 degrees, buckled roads, slowed trains, and pushed utilities toward the limit of the electrical grid’s capacity.

Scattered power outages affected customers — including some in Richmond — along the East Coast, and usage approached record levels.

Temperatures in New York City passed 100 yesterday for the second day in a row, the first back-to-back readings that high since 1999, the National Weather Service reported.

With people cranking up their air conditioners, Valley Forge, Pa.-based PJM Interconnection — which operates the largest electrical grid in the U.S. — instituted emergency procedures to conserve electricity. PJM’s grid covers about 51 million people in 13 states and the District of Columbia.

Northern Virginia Electric Cooperative in Manassas activated its load-management system, which turns off electric water heaters and cycles the air conditioners of about 46,500 subscribers.

Dominion Virginia Power asked about 25 commercial and industrial customers to curtail their service or switch to standby generators. Those customers are on special rate programs in which they receive a credit for reducing their electricity use when the utility requests.

Dominion Virginia Power subscribers were consuming a little more than 18,000 megawatts yesterday afternoon.

“We’re not anticipating setting a record,” company spokesman Jim Norvelle said. And, he noted, usage should be markedly less today, which is expected to be about 10 degrees cooler than yesterday.

On Tuesday, Dominion Virginia Power customers’ demand peaked at 18,983 megawatts. The company’s record demand was 19,688 megawatts on Aug. 8, 2007.

Dominion Virginia Power is the state’s largest electric utility with more than 2.3 million customers.  About 2,900 customers in the Lakeside area of Richmond lost power for a short time yesterday afternoon.  The outage affecting four circuits occurred when a transformer failed during maintenance, according to Dominion Virginia Power.

In the Washington area, nearly 1,000 customers were without power yesterday.

Transportation officials cut the speed of commuter trains in suburban Washington and New York when tracks got too hot. Extreme heat can cause welded rails to bend under pressure.

Amtrak trains in Virginia ran late yesterday as a result of reductions in operating speeds because of the heat. “We’re seeing delays of 15 to 30 minutes,” Amtrak spokeswoman Karina Romero said.

Dominion charges customers a higher rate during the high-demand summer months for electric consumption above 800 kilowatt-hours a month.

The bill for a typical residential customer using 1,000 kilowatt-hours a month during the June-September period is $102.16, the company said. During October through May, the same monthly bill is $96.46, or 5.6 percent less.

8 signs that you may need to service or replace your HVAC system

Monday, January 18th, 2010

Is the air quality and temperature in your Richmond home or office less than you would like it to be? Lennox, one of our trusted manufacturers of heating, cooling, and air purification systems, offers the following information to help you improve your air — and save money doing it.

If you’re experiencing any of the problems on this checklist, you might want to consider making a change.  Take a look:

  1. Some of your rooms are too hot or cold. Duct problems, inadequate air sealing or insulation could be the cause. No matter how efficient your heating and cooling system is, if your home is not properly sealed and insulated against air leakage, you will not be as comfortable and your system will have to work harder.
  2. Your home has humidity problems and/or excessive dust. Poorly operating or improperly sized equipment could be to blame. Leaky ductwork can also cause these problems, so having it sealed may be a solution. Monthly maintenance of your heating and cooling equipment’s filters may also help.
  3. Your cooling system is noisy. Your duct system could be improperly sized or there may be a problem with the indoor coil of your cooling equipment.
  4. Your equipment needs frequent repairs and your energy bills are going up. In addition to the rise in energy costs, the age and condition of your heating and cooling equipment may have caused it to become less efficient.
  5. Dave Lennox Signature® Collection XP19 Heat Pump, the most quiet and efficient heat pump you can buy

    Your air conditioner or heat pump is more than 12 years old. Consider replacing it with newer, more efficient equipment. And, remember, high efficiency levels begin with ENERGY STAR.

  6. Your furnace or boiler is more than 15 years old. Consider replacing it with ENERGY STAR® qualified equipment. ENERGY STAR has set high efficiency guidelines for both types of heating systems.
  7. You leave your thermostat set at one constant temperature. You could be missing a great energy-saving opportunity. A programmable thermostat adjusts your home’s temperature at times when you’re regularly away or sleeping, and then brings it back to your preferred temperature for times that you are awake and doing things in the house.
  8. Your score on the ENERGY STAR Home Energy Yardstick is below five. That means you’re using more energy at home than most Americans and probably paying more than you need to on energy bills.
