July 8 (Reuters) - New York power prices edged lower on Monday despite hot weather forecasts for early this week, as the state has more than enough generation to meet the expected cooling demand even with reduced output from two nuclear reactors.

Entergy Corp reduced the 1,006-megawatt (MW) Indian Point 2 reactor, the third-biggest generating unit in the state, to about 25 percent power over the weekend for work on a valve. , and Constellation Energy Nuclear Group took its 630-MW Nine Mile 1 reactor off line early Monday, also to work on a valve.

Entergy and Constellation could not say when their reactors would return to full power, but electricity traders estimated both units would return within a few days.

Despite the loss of power from the two reactors, traders said prices were only in the $60s per megawatt hour for early this week, well below quotes last week in the $80s as load forecasts and temperatures came in much lower than expected.

Temperatures this week will reach 88 degrees F (31 C) on Monday and 90 on Tuesday and Wednesday before dropping back to highs in the 80s on Thursday and Friday, according to Last week, forecasters were calling for the mercury to top 90 each day early this week.

"We are not anticipating any issues on the system," New York Independent System Operator spokesman Ken Klapp told Reuters, noting demand forecasts are below what was expected for this time last week. NYISO operates the state's power grid.

On Monday, the NYISO forecast power usage would peak at 28,700 to 30,300 megawatts for the Monday to Wednesday period.

Last week, the NYISO forecast demand this week would reach 31,400 to 32,100 MW early this week. That is still well below the NYISO's all time record demand of 33,939 MW set in August 2006, before commercial and industrial power usage declined during the economic crisis.   Continued...
