Plant Summary (1) Electricity generation reflects the Company’s share of plant output. (2) Plant availability represents the percentage of time in the period that the plant was available to generate power regardless of whether it was running, and therefore is reduced by planned and unplanned outages. (3) In this summary, plant revenue represents revenue generated directly from plant activity and does not include portfolio or mark- to-market generated revenue. (4) Genesee 3 returned to service on January 15, 2012 after an unscheduled outage which commenced on November 11, 2011.
