Enmax is asking for bids from wind and small hydro to supply an additional 30,000 MWh this year, and 40,000 MWh a year for the next ten years. If the utility continues to prefer wind, its plan will require 8 MW-12 MW of new wind capacity.
"We had quite a bit of information from the first time we did this," says green power program co-ordinator Ed Hucman. "We have a good idea of what's available in the Alberta, British Columbia, Saskatchewan market place and I think we have a basic idea of what we want to do."
Revealing few details, Hucman says Enmax wants to expand into the commercial electricity market with green power, in addition to signing up more residential customers. Starting in 2001, Enmax's Calgary franchise will be dissolved when Alberta opens its power market to full retail competition. At that time, Enmax will have to compete to retain its customers and can solicit consumers in other parts of the province.
Greengrid Electric, an Ontario wind retailer, has already shown interest in the Alberta market. Greenmax draws power from four 600 kW Vestas turbines owned by Calgary based Vision Quest Windelectric.
