The Public Service Commission set 10-year energy conservation goals Tuesday that are significantly stronger than Florida's major electric utilities had proposed but well short of what environmentalists wanted.

The goals differ for each utility but overall are expected to produce energy savings of about 3.5 percent over the next decade, said Susan Glickman, spokeswoman for the Southern Alliance for Clean Energy and Natural Resources Defense Council

That's only about a third of the 10 percent savings on power sales the two groups had proposed. A consultant hired by the commission had suggested 9 percent. Glickman said those recommendations are similar to goals set by the leading energy efficiency states.

The commission's staff, though, proposed only 1.18 percent in a recommendation the panel rejected last month. The staff then submitted a revised recommendation for 2.11 percent.

"Despite a thoughtful discussion on how to make energy efficiency more available ... in the end the commission set disappointing energy efficiency goals," Glickman said. "They were being held back by the advice they were receiving from their staff."

The five-member panel unanimously voted to strengthen the final staff recommendation by adding financial incentives for customers of Florida's four largest power companies to take such measures as buying energy-saving light bulbs and appliances and insulating water heaters.

The details of those incentives will be outlined in implementation plans the utilities must submit for commission approval in about three months.

The staff recommended against the incentives because many consumers, labeled "free riders," likely will take those steps without them.

Commissioner Nancy Argenziano disagreed.

"There are a lot of people who just can't do it; I think they need some incentives," Argenziano said. "They'd loved to be able to go out and buy a more energy efficient refrigerator or an air conditioning unit. They can't afford $6,000, $5,000, $800.

The commission also authorized utilities to provide up to $24.5 million in incentives for installing solar energy systems _ nearly doubling rebates already available from the state.

Another key decision was to use a cost-effectiveness test that counts conservation savings as a benefit rather than a previous method that viewed them as a cost to consumers. Glickman said that was a "step forward."

The goal for Florida Power & Light Co., the state's largest electric utility, is expected to have a revenue impact of $180 million over 10 years _ nearly twice what the company proposed _ but well under the $629 million sought by the environmental groups.
