* Volumes too low for so many CEE exchanges
* Next market coupling likely Czech Republic
* New Polish energy law needs changes

PRAGUE, Dec 2 (Reuters) - Central and eastern European power exchanges need to consolidate in order to create an efficient electricity market in a region with low -- but growing -- liquidity, the head of Poland's POLPX said on Thursday.
Current volumes are too low to support so many exchanges in a region where traders are keen to see truly liquid bourses offering financial products, Grzegorz Onichimowski said in an interview.
"It is a good question whether in the future there is room for all these exchanges," he told Reuters. "There is not enough liquidity for so many exchanges regionally."
"There is no doubt we need to consolidate, otherwise it would be too difficult to create financial futures and other products."
Hungary's HUPX and the Prague-based Power Exchange Central Europe are also pushing to establish a foothold as the centre of a regional power-trading hub in central and eastern Europe. Romania also operates its own exchange.
But the Prague bourse, for example, has run into headwinds in Hungary where HUPX has soaked up much of the volume due in part to support from state-owned electricity company MVM.
This situation underscores problems these bourses face, especially as more players look to tap into a potentially lucrative trading market due to good grid connections and plenty of capacity, Onichimowski said.
"Our main problem is threats from initiatives to set up other exchanges," he said, citing a plan from the Warsaw stock exchange to launch its own electricity market.
This sort of competition means POLPX will likely see volumes limited to about 20 to 30 percent higher on the day-ahead market and roughly the 2010 level on the forward market of about 30 TWh, Onichimowski said.
The expected market coupling with NordPool in mid-December will help boost liquidity, though he predicted the full 600 MW capacity on the cable linking the markets will not be used due to technical limitations, he added.
"We would like to develop other market couplings," Onichimowski said. "From our perspective it is more important to look next to the south because there are more trading opportunities with the Czech Republic than Germany.
"In Germany there are technical problems with loop flows due to substantial wind generation. It is quite difficult to use those connections." Poland's new energy law, which requires companies to trade at least 15 percent of the power they generate either on POLPX or other public platforms, has also driven liquidity since it took effect in August.
Utility traders have said the measure could crimp development of the market because it has translated into higher costs and has thrown up some hurdles to trade -- issues Onichimowski said needed to be dealt with.
He said POLPX would soon be changing the rules regarding its clearing house IRGiT and would like to introduce new brokers into the market to create more competition and lower prices.
POLPX is also working with lawmakers about other issues, including the licensing system and a requirement for each generation plant to have a licensed broker on site.
It would also make sense for traders on established markets like EPEX to be able to easily trade on POLPX, something that is not possible now, he added.
"The changes are taking place," he said. "A balance needs to be found between transparency and a company's ability to do business. (Reporting by Michael Kahn, Editing by Alison Birrane)
