* Spot market rises on morning supply squeeze * Curve prices are lifted by EU debt agreement LONDON, Oct 27 (Reuters) - UK gas prices rose on Thursday morning as spot prices were boosted by a shortage of supply while forward prices were lifted by the European Union's agreement to tackle the euro zone's sovereign debt crisis. UK NBP gas prices for immediate delivery were around 60.75 pence per therm at 0915 GMT, up 0.75 pence from Wednesday afternoon. Prices for next-day delivery were up 0.4 pence during the same period to 60.50 pence a therm. November gas prices, however, remained flat around 62.30 pence as the outlook for next month was unchanged. "The system was a little bit short this morning so, consequently, spot prices rose," one gas trader said. "But it's nothing serious given that storage levels are over 90 percent full," he added. Further out on the curve, prices also rose as markets reacted to news from Brussels that the EU had agreed on several measures to address Greece's sovereign debt crisis. Gas prices for delivery in summer 2012 were at 62.45 pence a therm on Thursday morning, up 0.45 pence since Wednesday afternoon. But the contract remains overall weak and is still down more than 8 percent since prices began to fall in early September. WEATHER Britain's Met Office forecast temperatures to remain stable between Thursday and Friday, and to slightly increase during the weekend, although more showers and stronger winds were to be expected. DEMAND & SUPPLY The British gas system was short nearly 30 million cubic metres on Thursday morning, but the system could narrow the gap to around 10 million cubic metres over the course of the morning. TECHNICALS NBP summer 2012 gas rose to 62.45 pence per therm, back to its 200 exponential daily moving average (DMA) value. But the contract's 50 DMA remains slightly below its 100 DMA, around 64.50 pence per therm. It is the first time this year that the short-term DMA has dropped below the longer-termed 100 DMA. POWER Day-ahead baseload (24 hours delivery) power prices also fell, shedding 35 pence per megawatt-hour (MWh) to 47.85 pounds a MWh. Summer 2012 electricity fell below 51 pounds to 50.75 pounds a MWh. GAS-Please click on the following for information about UK and Belgian prices, field maintenance and field start-ups.
