* Distribution related cost
** Supply related cost. Note: The RGGI program compliance price component is calculated using the average marginal CO2 emission rate produced by ISO-NE’s newly developed all-unit locational marginal unit (LMU) methodology. The result differs slightly from that reported by RGGI as RGGI continues to use the average marginal CO2 emission rate produced by ISO-NE’s fuel type assumed (FTA) methodology that assumes an aggregate oil/natural gas unit as the marginal unit. If adjusting for Canadian imports, which are not subject to the RGGI requirements, the Commission calculates the cost to ratepayers to be 0.11 c/kWh.
Energy Resource obligations: Electricity supply contracts are intended to facilitate the development of electric power generating plants and/or provide electric rate stability benefits. These contracts are also designed to provide benefits in the form of lower wholesale regional wholesale electricity costs and to encourage renewable energy development. This category includes both legacy stranded costs and post-restructuring long-term contract costs/benefits.
Efficiency Maine Trust charge: The Efficiency Maine Trust (EMT) administers energy efficiency and conservation programs throughout the State for the purpose of lowering the costs of electricity for Maine’s residents and business. A portion of the Efficiency Maine Trust’s budget is funded by a charge included in electricity rates. The EMT website has information on available programs: (www.efficiencymaine.com)
Low income program costs: Maine statute provides for electricity bill discounts for low income customers. The program is funded by a charge included in electricity rates.
Maine Public Utilities Commission Assessment: Provides funds for the operations of the Maine Public Utilities Commission, in addition to funds provided through assessments in other utility rates, including telephone, natural gas, and water utility rates. The Maine Public Utilities Commission regulates the rates and services of public utilities and oversees the competitive retail electricity market.
Office of the Public Advocate Assessment: Provides funds for the operations of the Office of the Public Advocate, in addition to funds provided through assessments in other utility rates, including telephone, natural gas, and water utility rates. The Office of the Public Advocate advocates on behalf of residential and small commercial ratepayers in Maine Public Utilities Commission, regional and federal proceedings.
Renewable resource portfolio requirement costs: The renewable resource portfolio requirements in Maine and other New England states are designed to encourage renewable resource development and resource diversity in New England with the objective of promoting regional electricity cost stability and lower regional electricity costs as well as achieving environmental benefits. A recent MPUC report contains a discussion of the benefits and costs of the portfolio requirement:
(MPUC RPS Report 2011 - Review of RPS Requirements and Compliance in Maine)
Regional Greenhouse Gas Initiative (RGGI) compliance costs: RGGI is a nine state program to reduce greenhouse gas emissions from electricity generating power plants that serve New England, New York, Maryland and Delaware. The costs of the program are paid directly by power plants that generate greenhouse gas emissions with Maine’s proceeds used for energy efficiency programs. (RGGI website)
