Regional grid operator PJM Interconnection says it authorized more than 750 electric transmission improvement projects last year costing more than $5 billion to prepare for massive shifts in the way power is produced in the region. PJM, which is based in Valley Forge, said the unprecedented switch from older coal-burning power plants in Appalachia to new natural-gas and renewable energy projects is driving the need to reconfigure the grid to maintain a reliable electricity supply.

PJM Interconnection's board on Thursday authorized 11 improvements to the electrical transmission grid in its 13-state region. The regional grid manager, which is based in Valley Forge, said the projects are expected to cost $59 million and will yield $815 million in savings over 15 years. The projects, which are enhancements to the existing transmission system rather than new lines, include three upgrades in Pennsylvania, all located near the Susquehanna River south of Harrisburg.

It could have been worse. You could have been in Saudi Arabia, where the temperature was 104 degrees yesterday. The electric company probably wishes you were. "It was a tense afternoon," said Peco Energy public relations manager David Hackney. But the temperature climbed to only 88 - five degees below the record of 93 set in 1936 - and customers apparently heeded the utility's pleas to conserve. The utility avoided any voltage reductions or temporary service interruptions, still the utility yesterday afternoon hit a record for usage in May. Demand reached 6,800 megawatts, Hackney said.

PJM Interconnection, the regional electricity grid operator, has called on customers to conserve power on Tuesday, when arctic conditions are expected to push demand to the limits of the transmission system. The grid on Tuesday evening is projected to surpass the winter demand record set on Jan. 7, said Paula DuPont-Kidd, a PJM spokeswoman. Utilities are asking consumers to conserve electricity especially from 6 a.m. to 10 a.m. on Tuesday as well as from 5 p.m. to 9 p.m. Utilities urged electric heating customer to set their thermostats lower than usual, if health permits, to turn off unneeded lights and appliances, and to delay using major appliances like stoves, dishwashers and clothes dryers.

What a difference three years can make. A cascading blackout, caused by inadequate tree trimming, poor employee training and computer failure, thrust the Northeast into darkness on the mild summer evening of Aug. 14, 2003. This summer, a nationwide heat wave pushed utilities to their limits not once but repeatedly. PJM Interconnection - a grid traffic cop that coordinates the transmission of electricity for 51 million customers in 13 states, including Pennsylvania and New Jersey - set a usage record July 17, only to break it Aug. 1, and then again the next day. So far in '06, the national system has strained, but largely withstood the pressure.

The parent of Peco Energy Co. yesterday unplugged its $17 billion bid to acquire Public Service Enterprise Group Inc. after failing to reach a deal with New Jersey utility regulators. Exelon Corp. had counted on the merger to give it scale in one of the nation's largest power grids. The Chicago company, which threatened in August to pull the plug on the deal, would not comment on its plans. "We are very disappointed that the merger cannot be completed," John W. Rowe, Exelon's chairman and chief executive officer, said in a statement released after the stock market had closed.

PJM Interconnection said yesterday that, as electricity use soared Wednesday, the region's power grid set a record in the amount of peak need that was met by so-called demand response, in which power customers are paid market rates to curtail consumption. With high temperatures and humidity across the eastern portion of its 13-state electricity pool, PJM said demand topped 139,700 megawatts - less than the record of 144,644 megawatts set Aug. 2, 2006, but the highest so far this year.

NewPower Holdings Inc. said yesterday that it was in discussions to be acquired by a British utility for about $66 million. The electricity and natural gas retailer has 680,000 customers in five states, including 192,000 electricity customers in the Philadelphia area. A spokeswoman said its customers would not be affected by the possible sale. The company, which was started in January 2000, has had cash-flow concerns for the last year, and it is 44 percent owned by Enron Corp.

The threat of rolling blackouts or voltage cutbacks eased late yesterday as clouds and rain cooled off portions of central Pennsylvania and eastern Maryland. The temperatures in the Philadelphia region are expected to soar well above 90 degrees today and tomorrow, again putting extreme demands on the region's electric-power grid. The Philadelphia Health Department and National Weather Service in Mount Holly yesterday issued an excessive-heat warning for the weekend. The heat index, which is a combination of humidity and air temperature, could hit 105 today, officials said.

Think of it as Mother Nature's economic stimulus. Electricity consumption has dropped dramatically this summer because of the mild weather, and it is translating into more manageable electric bills. PJM Interconnection, the regional grid operator, says electricity demand in the mid-Atlantic states was down 13.5 percent in June compared with last year. Peco Energy Co. customers used 14.9 percent less power in June than they did a year ago, and sales are off 2.5 percent for the first six months of the year, according to PJM. Public Service Electric & Gas, the New Jersey utility, sold 17 percent less power in June, and 4.5 percent less for the year.
