* Czech-Slovak power market integration boosts liquidity
* Shared grid and language helped process
* Coupling key for potential regional market

PRAGUE/LONDON, Sept 30 (Reuters) - The merger of the Czech and Slovak electricity markets shows other central and eastern European countries that integration can work and could spur more to do the same.
The success so far of the Czech-Slovak electricity market integration on Aug. 31 -- marked by increased liquidity -- shows that combining markets can be done. [
]Central and eastern Europe offers traders a potentially lucrative place to trade power but fragmented national power markets and a lack of liquidity stands in the way.
"It is a good step forward and shows what needs to be done in the region," Kasper Walet, managing director at Dutch energy trading and risk management consulting firm Maycroft, said.
"Market coupling will certainly have benefits but you also need some liquid exchanges if you want the same market system we have in northwestern Europe."
Jurgen Wahl, an executive board member of the Austrian energy exchange EXAA -- one of Europe's main power exchanges -- said he was impressed by the speed of the integration compared with other coupling schemes such as one aimed at integrating Belgian, Luxembourg, Dutch, German and French power markets.
"It's remarkable because two eastern European countries, two emerging markets, managed to do something within a couple of months which some very advanced markets need a lot of effort and long discussions to set up," Wahl said at a recent conference in London.
Like the rest of Europe, the power exchange landscape in central and eastern Europe is fragmented but European Union officials envision a future with one exchange to help drive down prices for consumers.
LANGUAGE
As a single nation until 1993, the Czech Republic and Slovakia had several advantages, including a shared power grid and a common understanding of languages, said Chris Dinsdale of KPMG's Global Power and Utilities team.
"It's the only one on the table that's progressing and putting liquidity on the table," he said. "And they have first mover advantage, which they'll keep for the time being."
But some traders said all had not been smooth with the Czech and Slovak move, citing a few instances of market splitting, when the calculated flow of power is higher than the market coupling capacity received.
And while the two grids were initially designed as one, there were still technical and political hurdles the operators needed to solve to combine their networks.
Other countries looking to combine their markets face similar issues despite investments across the region of internal and cross border lines needed for effective coupling, Michael LaBelle of the Regional Centre for Energy Policy Research at the Corvinus University of Budapest, said.
"The coupling of the Czech and Slovak markets is a great example of how coupling the already interconnected national electricity markets can increase market efficiencies," he said.
"CEPS (the Czech grid operator) has really been out there for a number of years pushing for greater regional integration. I think it shows persistence pays off."
David Kucera, chief executive of the Power Exchange Central Europe (PXE), said coupling had attracted more traders and boosted liquidity.
The PXE is making a big push to be the main hub for regional power trading, and presently operates in the Czech, Slovak and Hungarian markets.
"The liquidity is better, that's for sure," he said. "But it's really too early to comment on whether it will lead to market coupling between other countries."
Romania and Hungary have been trying to couple their power markets, something that could provide Hungarian consumers with cheaper Romanian electricity.
But concerns that a flood of cheap Romanian power denting the profits of state-owned power company, MVM, may explain the political resistance to market coupling, analysts said.
"My feeling is Romania has a hegemonistic interest in setting up an exchange in Hungary, and that is what the Hungarians do not like," said EXAA's Wahl.
"One of the other things is that the political situation is always changing in the countries, and this delays projects."
