* Says CEZ not tipped off about raid
* EU interviewed about 20 staff
By Michael Kahn
PRAGUE, Dec 1 (Reuters) - European Commission regulators investigating Czech power group CEZ <
> are likely focusing on issues surrounding the lignite market rather than the wholesale power market, a top CEZ official said on Tuesday.Director of Sales and Trading Alan Svoboda told Reuters the probe likely stems from a long-term dispute over brown coal deliveries and prices with privately-owned miner Czech Coal. Another potential area was whether it blocked rivals' plans to build competing power plants.
"The investigators interviewed about 20 managers and staff and after two days they took some documents related mainly to coal mining," Svoboda said in an interview on the sidelines of an energy conference in Prague.
"I doubt there will be any significant investigation into the wholesale power market."
On November 24, the Commission said that officials had carried out unannounced inspections at CEZ headquarters and another firm located in the Czech Republic to investigate whether they violated EU competition laws.
Svoboda, whose company has stated it was cooperating fully with the probe, said the recent market coupling between the Czech and Slovak power markets and a liquid electricity exchange serving the region offer evidence of a transparent market.
TRANSPARENT MARKET
"I can point to many things to show how transparent the power market is," Svoboda said. "We have no way to distort the market even if we wanted to, we are a price taker on the wholesale market."
Privately-held investment group J&T, a CEZ partner in some energy projects, has also said it was involved in the probe. The two firms jointly bought German coal mine MIBRAG near the Czech border earlier this year.
J&T also bought Czech assets from International Power <IPR.L> and has agreed to sell a part of the package, a 49 percent stake in a Prague heating firm, to CEZ.
Czech Coal had complained to the Czech competition office over the IPR asset sale but the regulators here cleared the deal. The miners, however, have complained also to the European Commission, Svoboda said.
He also said the raid caught CEZ by surprise, requiring the company to call back a number of officials from a business trip abroad and putting a damper on speculation it was tipped off.
The Commission has said it would look into how a Czech news website obtained information about the impeding raid a day before it started.
"The only preparation we had was about one-and-a-half years ago when the Commission was visiting other utilities and we realised that sooner or later we would also receive a visit, since we belong to the top 10 European utilities" Svoboda said.
"We instituted guidelines on how to cooperate with regulators so any potential on site investigation would be smooth." (Editing by James Jukwey) ((michael.kahn@thomsonreuters.com; +420 224 190 443; Reuters Messaging: michael.kahn.reuters.com@reuters.net)
