I spoke with XCEL today - there is still a ways to go to complete the solar garden program, and its not certain if it will be completed before the end of the year. The hope is if the process runs past the end of the year we will have 12 Megawatts in 2012 - but solar gardeners might lose the benefit of the 1603 tax grant.
There's a great team of people working within XCEL to make solar gardens happen. They pointed out that they have a spiffy new website and mailing list- but they still need people to join. Please visit the site, scroll to the bottom of the page, and sign up for XCEL's list.
