PRAGUE, Dec 5 (Reuters) - Central European day ahead power prices rose slightly on Wednesday as forecasts for colder weather offset a slight increase in renewables, while the Czech Cal '13 traded near a record low, traders said.

Czech, Slovak and Hungarian electricity for Thursday delivery rose 1.7 percent to 54.57 euros ($71.41) a megawatt-hour (MWh) on regional exchanges.

The three Central European countries combined their day ahead markets in September, but since then prices have diverged frequently, with Hungary often trading higher.

'It is cold weather and day ahead was almost the same as for today. The weekend went up due to lower wind,' one trader said.

Data from Thomson Reuters Point Carbon showed temperatures falling to 2 degrees below zero leading to an increase in forecast consumption.

Wind power generation in Germany was forecast at 4.6 gigawatts (GW) and solar power production at 1.5 GW.

Further along the curve, the Czech Cal '13 baseload traded flat at 45.70 euros on the Prague-based Power Exchange Central Europe. The contract reached an all-time low of 45.60 euros on Nov. 30 and has hovered around that level since.

Around the region, the benchmark German Cal' 13 contract shed 10 cents to 46.10 euros in afternoon trading on Germany's EEX exchange.

Serbian grid operator Elektromreza Srbije (EMS) announced the total cross-border power capacity available for allocation in January through a joint auction with Hungary.

Bosnian grid operator Nezavisni Operator Sistema (NOS) published the results of its cross-border power capacity auction for next year.

Day ahead on Poland's POLPX exchange fell to 184.45 zlotys ($58.41) from 184.57 zlotys.

Brent crude oil rose slightly to just above $110 per barrel on hopes of stable growth in China, but weak euro zone retail data and U.S. jobs figures kept gains slim.

EUAs for December delivery, the benchmark EU carbon contract, rose 1.4 percent to 5.80 euros a tonne at 1445 GMT.
