During last decade sponsored 230 teacher workshops and partnered with more than 90 schools, colleges and educational organizations to reach more than 4,400 teachers and 352,000 students. Contributed more than $3.1 million to programs targeting K-12 grades. AEP Foundation donated $11.5 million to 68 organizations in 2007. Continue to grow support for United Way and other forms of giving, even in economic downturns when support is needed most. Continue partnership with IBEW for United Way campaign and other community service initiatives. In 2007, employees contributed $2 million to United Way; AEP added $1 million. Glossary Advanced Coal Technologies: Includes supercritical, ultra-supercritical, circulating fluidized bed and integrated gasification combined cycle (IGCC) technologies. Cap-and-Trade: A market-based system of limiting emissions in which a limited number of emissions permits are issued in the aggregate (cap); these permits are then freely exchanged in markets (trade). Carbon Capture & Storage (CCS): The capture, compression, transport and storage of CO2 emissions. Carbon Dioxide (CO2): A colorless, odorless, non-poisonous gas that is a normal part of Earth’s atmosphere. Carbon dioxide is a product of fossil fuel combustion as well as other processes and is considered a greenhouse gas because it traps heat radiated by the earth into the atmosphere. Climate Change: Changes in climate that depart from normal variability, representing significant changes in averages and/or extremes. Congestion: A condition that occurs when insufficient transfer capacity is available to implement all of the preferred schedules for electricity transmission simultaneously. Demand: Rate at which electric energy is delivered to or by a system or part of a system, generally expressed in kilowatts or megawatts, at a given instant or averaged over any designated period of time. Demand-Side Management (DSM): The planning, implementation, and monitoring of utility activities designed to encourage consumers to modify their patterns of electricity usage. Emissions: Anthropogenic releases of gases to the atmosphere. In the context of global climate change, they consist of greenhouse gases. Extra-High Voltage (EHV): The electric utility industry generally considers EHV to be any voltage of 345 kV or higher. Greenhouse Gas (GHG): Collective term for gases such as carbon dioxide that trap heat in the atmosphere and contribute to climate change. Grid: An interconnected network of electric transmission lines and related facilities. Megawatt (MW): One million watts of electricity. A unit of power equal to 1,000 kilowatts. Plant Efficiency: The percentage of total energy content of a power plant’s fuel that is converted into electricity. The remaining energy is lost to the environment as heat. Portfolio Standards: Guidelines or requirements that total electricity supply include one or more minimums for particular sources, such as renewable energy. Reliability: The degree of performance of the elements of the bulk electric system that results in electricity being delivered to customers within accepted standards and in the amount desired. Renewable Energy Resources: Energy resources that are naturally replenishing but limited in the amount of energy that is available per unit of time. They include biomass, hydro, geothermal, solar, wind, ocean thermal, wave action and tidal action. Sustainable Development: Coined by the Brundtland Commission as development that “meets the needs of the present generation without compromising the ability of future generations to meet their own needs.” Generally, means development that includes environmental sustainability, economic sustainability and social-political sustainability. Transmission System: An interconnected group of electric transmission lines and associated equipment for moving or transferring electric energy in bulk between points of supply and points at which it is transformed for delivery over the distribution system lines to consumers, or is delivered to other electric systems.
