Sullivan,
I am not sure how it works in your state, but those incentives out here are done through the power company. It is actually somewhat hard to find the incentives. My company is very heavy in to green test & measurement devices and it is often times a nightmare to find how to get to the incentive money.
Every power company is required to have a department of economic development. If you call up the company and ask for it, only about 50% of the time will the person know what you are talking about. Just call back over and over until you get someone that knows about it. The person in charge of economic development will either directory know about the program, or will know of who/what company is in charge of it in your state. The good news for you is, it is often a lot of red tape, but if it is hard for you to find, then it is for your competitors as well.
Here is one of the best resources I have found on the web. Click on your state, then click on a program. It usually has the contact name, number, website, email for the program.
