Explosions, gunfire rock hydropower plant
The gunmen, believed to be militant fighters, entered the station at 04:20 a.m. Moscow time to place explosives and shot two guards dead, local police were quoted as saying.
One hour later, three explosions occurred with an interval of five to six minutes near the small town of Baksan in the North Caucasus republic of Kabardino-Balkaria, damaging part of the facilities and triggering a fire at the first and second floors of the power plant.
A fourth explosion was reported later, but causing minor impact.
Local authorities played down the risks of any floods as the water gate has been timely closed. Neither would the local electricity supplies be affected as electric power has been dispatched from other stations to the area.
Meanwhile they did not rule out the existence of other explosive devices at the power plant, which has already been cordoned off. Orders have been given to beef up security of all the power plants in southern Russia.
Local police has called the incident a terrorist attack. A law enforce source was cited by the RIA Novosti news agency as saying that the same group of assailants may be responsible for an earlier attack on police.
"At 3:15 a.m. a police building was attacked with a grenade launcher in the city of Baksan. There were no casualties," said the source.
Baksan hydropower plant was built between 1930-1936.
On June 11, a total of six TV and radio broadcasting stations were attacked overnight at various districts of the republic, causing neither casualties nor disruption of normal operation of the stations.
Violence is common in Russia's mainly Muslim North Caucasus republics, especially Chechnya, Dagestan and Ingushetia, with militants frequently targeting police and officials as representing the Russian authorities.
Moscow claimed to tackle the problem of unemployment, clan rivalry and corruption as these are viewed as the reasons for violence in the region.

Wind power making gains as competitive source of electricity
TORONTO - It's taken a decade of technological improvement and a new competitive bidding process for electrical generation contracts, but wind may have finally come into its own as one of the cheapest ways to create power.
Ten years ago, Ontario was developing new wind power projects at a cost of 28 cents per kilowatt hour (kWh), the kind of above-market rate that the U.K., Portugal and other countries were offering to try to kick-start development of renewables.
Now some wind companies say they've brought generation costs down to between 2 and 4 cents — something that appeals to provinces that are looking to…
