The electrical power grid that powers Northern America is not a single grid, but is instead divided into multiple wide area synchronous grids. [1] The Eastern Interconnection and the Western Interconnection are the largest. Three other regions include the Texas Interconnection, the Quebec Interconnection, and the Alaska Interconnection.
The Michigan Public Service Commission Is calculating a new rate to pay solar customers who send energy back to the grid; the commission is using measurements of inflow and outflow of electricity to calculate the rate. In other states that have ended net metering, the new rates range from 75 to 95% of the retail rate.
In 2018, three more states made similar changes. For example, compensation in Nevada will go down over time, but today the compensation is at the retail rate (meaning, solar customers who send energy to the grid get compensated at the same rate they pay for electricity). In Arizona, the new solar rate is ten percent below the retail rate. [21]
Maintaining an effective grid requires management of three different but related sets of flows – the flow of energy across the grid; the exchange of information about power flows and the equipment it moves across; and the flow of money between producers, marketers, transmission owners, buyers and others.
The simple rate charges a specific dollar per kilowatt hour ($/kWh) consumed. The tiered rate is one of the more common residential rate programs. The tiered rate charges a higher rate as customer usage increases. TOU and demand rates are structured to help maintain and control a utility's peak demand. [6]
Solar panels in Cleveland. Solar power in Ohio has been increasing, as the cost of photovoltaics has decreased. Ohio installed 10 MW of solar in 2015. [1] Ohio adopted a net metering rule which allows any customer generating up to 25 kW to use net metering, with the kilowatt hour surplus rolled over each month, and paid by the utility once a year at the generation rate upon request.
The United States National Grid (USNG) is a multi-purpose location system of grid references used in the United States. It provides a nationally consistent "language of location", optimized for local applications, in a compact, user friendly format.
Plug-in electric vehicles have the potential to be utilized to provide ancillary services to the grid, specifically load regulation and spinning reserves. Plug-in electric vehicles can behave like distributed energy storage and have the potential to discharge power back to the grid through bidirectional flow, referred to as vehicle-to-grid (V2G ...
