I have finally found some information on Maine wind power production - on the FERC website, which has quarterly reports on industrial wind farms:
First Wind's Stetson I& II (capacity 82.5MW (called "Evergreen Wind Power V LLC" on the FERC website) reported 38,000 MWH sold to the grid for the second quarter of 2009. This is barely over 20 percent of installed capacity. For the same quarter of 2010 Stetson I & II reported 32,000 MWH sold to the grid - 17.5% of installed capacity.
First Wind's Mars Hill, capacity 42 MW and called "Evergreen Wind Power LLC" on the FERC website, reported 30,000 MWH sold to the grid for the second quarter of 2009. This is 32% of installed capacity. For the same quarter of 2010 it reported 24,000 MWH sold to the grid - 25.8 % of installed capacity.
Maine's summer of 2010 included some of the hottest weather in memory. The highly polluting Wyman plant, which burns oil, was fired up and operated when necessary to generate power to keep the grid stable. Very little wind power was available at the time. When it is hot in Maine power demand is high and there is usually little wind blowing. At the very time the grid needs more power, wind does not provide it.
Wind farms have impressive "installed capacity" on paper, but their record of output is fractional at best, irregular, and unpredictable, and has proved to be not very useful when it is needed most.

Replying to my own November 7 Post:
I have since learned of a misunderstanding I had: on the FERC website, Stetson I (57 mw installed capacity) is called "Evergreen Wind Power V, LLC" and Stetson II is called "Stetson II, LLC" (26MW installed capacity).
Sorry about the error.
I did not check with FERC on retail contracts. Certainly there is no industry to buy that power in that part of Maine. Eastern Maine Coop is the local distributer, and I understand that all Stetson power goes direct to the grid, and nothing to Eastern Maine.
Could you make up a spreadsheet with the FERC data for about 6-8 quarters for each wind facility in Maine. Here is an example of the wind facilities in New York State which also underperformed.
Below is the URL of a table that shows the performance of New York State's wind turbines. http://www.dailyenergyreport.com/wp-content/uploads/2011/06/NY_CF20...
The Vendor promises were capacity factors of 30% to 35%, before installation. The reality, after installation: Installed capacity, MW: 1035.5 in 2008; 1,274 in 2009: 1,274 in 2009; 1,348 in 2010 Production, MWh: 1,282,325 in 2008; 2,108,500 in 2009, 2,532,800 in 2010 Capacity factors: 14.1% in 2008; 18.9% in 2009; 22.7% in 2010 The data for the table was obtained from the 2011 New York ISO Gold Book http://www.nyiso.com/public/webdocs/services/planning/planning_data...
Because no wind turbines were added during 2010, the 22.7% capacity factor of 2010 is the best proof of the lack of performance of the New York State wind turbine facilities.
This reality is not unique to NY State. It has replicated itself in The Netherlands, Denmark, England, Germany, Spain, Portugal, Ireland, etc. The production less than promised, added to the CO2 emissions reduction less than claimed, as shown in below articles, makes further investments in wind energy an extremely dubious and expensive proposition.
