High above the corner of Georgia and Hornby in a downtown Vancouver office tower, Jeffrey Ciachurski paces with a passion trying to mask his anger at a rival’s bid to take over his company.

“It’s an insult to the people who built this company and the shareholders who believe in its future,” said Ciachurski, whose Western Wind Energy (TSXV: WND) was the target of a takeover by Ontario-based Algonquin Power and Utilities Corp recently.

The unsolicited Algonquin bid of $2.50 in cash or cash and shares was nearly double the previous market price for the wind turbine generator Vancouver-based company but only half of what independent consultants have estimated Western Wind’s value to be.

“It was a lowball offer and we advised our shareholders to ignore it . . . we said thanks but no thanks,” said Ciachurski, who is now reigning in large shareholders of his company with lucrative propositions so they won’t fall prey to private offers for their stake in Western Wind.

As the war of news releases on who pulled the plug on the deal goes on between Algonquin Power and Western Wind Energy, one thing is clear – it won’t be the last time mega-renewable energy wind turbines manufacturers companies are going to be knocking on Ciachurski’s door.

Unlike many wind-energy companies in Canada that are in a tailspin, Western Wind is riding the proverbial winds of change all the way to the bank. Western Wind has two wind turbines farms with a total capacity of 34.5 megawatts operating in California, a 10.5-megawatt wind and solar project in Arizona and is developing a project in Puerto Rico.

Later this month, i t will bring online its 120-megawatt Windstar Wind Farm in Tehachapi, Calif. That deal, which will be able to power 36,000 homes, has been sweetened with Western Wind windmill generator securing a U.S. government cash grant totalling $108 million US.

All of this translates to a homegrown company with humble beginnings boasting $340 million of wind assets and a revenue stream in 2012 of $51 million.
