Wolfe Island in Ontario was commissioned in summer 2009 with 86 Siemens wind turbines and an output of almost 200 MW. Photos (2): Dieter Fries

A buoyant market

The Canadian Wind Energy Association (CanWEA) has set itself an ambitious target. Canada aims to supply a capacity of 55,000 MW to the grid by 2025.

he Canadian wind power market continues to the tariffs for megawatt-class WECs. In Canada, the grow at a fast pace. By mid-July 2009, a wind term small wind turbines applies both to turbines with Tpow­er capacity of 2,854 MW had been connect­ a capacity of less than 10 kW, which are used for pri- ed to the Canadian grid. According to CanWEA’s esti- vate and secondary homes, as well as to turbines of up mations, 800 MW were installed in 2009 alone.

The majority of a capacity of 800 MW was installed. projects is located to the south of Ontario around the Great Lakes, where wind conditions similar to those near the sea shore prevail due to large areas of water. The first Canadian offshore wind farms are be- ing planned in this region. The first offshore projects in North Ameri- ca are also expected to go into operation here. Maintenance capacities must be increased

With a population of approximately 23 million mainly living in the large metropolitan conurbations, Canada has a grid infrastructure that is not developed well enough in all rural wind regions for large- scale wind power capacities to be integrated. Current debates in- clude extending the grid in Canada itself, but also strengthening the electricity lines to the US. Because of the large share of hydroelectric power, Canada can opt to conserve these reserves during strong winds and to sell them in peak load periods to the US. However, quality standards and data bases for wind assessments must be improved, as the yields of many wind turbines have not achieved the previously calculated target values. Relevant research measures should remedy the situation. The dynamic growth of the in Canada and the US has created a considerable demand for increasing mainte- nance combined with appropriate training. German companies in particular are currently utilising their experience with training in this area. The same applies to developing repair service as well as to tur- bine monitoring capacities.
