25. "In-service date" means the date a power supply source becomes available for use by a load-serving entity.
26. "Load-serving entity" means a public service corporation that provides electricity generation service and operates or owns, in whole or in part, a generating facility or facilities with capacity of at least 50 megawatts combined.
27. "Long-term" means having a duration of three or more years.

29. "Mothballing" means the temporary removal of a generating unit from active service and accompanying storage activities.
30. "Operate" means to manage or otherwise be responsible for the production of electricity by a generating facility, whether that facility is owned by the operator, in whole or in part, or by another entity.
31. "Participation rate" means the proportion of customers who take part in a specific program.
32. "Probabilistic analysis" means a systematic evaluation of the effect, on costs, reliability, or other measures of performance, of possible events affecting factors that influence performance, considering the likelihood that the events will occur.
33. "Production cost" means the variable operating costs and maintenance costs of producing electricity through generation, including fuel cost, plus the cost of purchases of power sufficient to meet demand.
34. "Refurbish" means to make major changes, more extensive than maintenance or repair, in the power production, transmission, or distribution characteristics of a component of the power supply system, such as by changing the fuels that can be used in a generating unit or changing the capacity of a generating unit.
35. "Reliability" means a measure of the ability of a load-serving entity's generation, transmission, or distribution system to provide power without failures, measured to reflect the portion of time that a system is unable to meet demand or the kilowatt-hours of demand that could not be supplied.
36. "Renewable energy resource" means an energy resource that is replaced rapidly by a natural, ongoing process and that is not nuclear or fossil fuel.
37. "Reserve requirements" means the capacity that a load-serving entity must maintain in excess of its peak load to provide for scheduled maintenance, forced outages, unforeseen loads, emergencies, system operating requirements, and reserve sharing arrangements.
