Captive power plants are generally used by power-intensive industries where continuity and quality of energy supply are crucial, such as aluminum smelters, steel plants, chemical plants, etc. [3] However, the radical cost declines for solar power systems have enabled the opportunity for less energy-intensive industries to economically grid defect by coupling solar PV with generators or ...
In August 2011, the Japanese Government passed a bill to subsidize electricity from renewable energy sources. The legislation will become effective on 1 July 2012, and require utilities to buy electricity generated by renewable sources including solar power, wind power and geothermal energy at above-market rates.

[a] The initiative was called the Arizona Solar Energy Freedom Act. It needed 225,963 signatures to get on the ballot. [4] As it was written, the amendment focused on the payment structure between utility companies and people who have solar panels and generate extra power that they sell back to the power grid.
Growth of net metering in the United States. Net metering is a policy by many states in the United States designed to help the adoption of renewable energy.Net metering was pioneered in the United States as a way to allow solar and wind to provide electricity whenever available and allow use of that electricity whenever it was needed, beginning with utilities in Idaho in 1980, and in Arizona ...
Grids with high penetration of renewable energy sources generally need dispatchable generation rather than baseload generation. Dispatchable generation refers to sources of electricity that can be programmed on demand at the request of power grid operators, according to market needs.
The 150 MW Andasol solar power station is a commercial parabolic trough solar thermal power plant, located in Spain.The Andasol plant uses tanks of molten salt to store captured solar energy so that it can continue generating electricity when the sun is not shining.
A photovoltaic system, also called a PV system or solar power system, is an electric power system designed to supply usable solar power by means of photovoltaics.It consists of an arrangement of several components, including solar panels to absorb and convert sunlight into electricity, a solar inverter to convert the output from direct to alternating current, as well as mounting, cabling, and ...
NUGs may be privately held facilities, corporations, cooperatives such as rural solar or wind energy producers, and non-energy industrial concerns capable of feeding excess energy into the system. [3] An independent water and power producer (IWPP) is similar to an IPP, but with a unified process to also output usable treated water. [4]
