6.3 GW of wind have already been added in 2009, while more than 2 GW are under construction and scheduled for activation by year’s end, EER says.

“At face value it appears that the US market could witness its second-best growth year to date; however, if you remove spill-over build originally meant for completion in 2008, 2009 market activations will probably be closer to half of 2008 levels,” according to Senior Wind Analyst Matthew Kaplan.

In the first quarter of this year, most market participants expected a significant drop in 2009 wind activations to well less than 6 GW based on frozen financial markets. However, a combination of wind projects planned for 2008 spilling over into 2009 and construction activity by developers eager to qualify for American Recovery and Reinvestment Act 2009 (ARRA) provisions, points to US market growth nearing approximately 8 GW in 2009, according to Kaplan.

Despite this strong signal of growth, challenges for the US wind market remain: Falling electricity demand, unprofitable merchant wind prices, and declining fixed power purchase agreement prices have vexed project developers looking for electricity off-take.

However, ARRA provisions and longer-term policy drivers, including RPS incentives, may help counter these short-term economic inhibitors, according to EER.

5 GW of wind projects are currently under construction – many of which will be activated in 2010. While project construction is picking up to obtain grant funding, delays due to the financial crisis indicate 2010 wind activations are more likely to remain stagnant compared with 2009.

However, construction may surge so that wind projects meet grant requirements. “The 2010 picture is not yet complete. On one hand, the project development environment continues to face serious bottlenecks, but on the other hand, the ARRA promises the wind industry more incentives than it has ever seen before,” says Kaplan.
