Net metering is a electricity policy for consumers who own, generally small, renewable energy facilities, such as wind or solar power, or uses vehicle-to-grid systems. "Net", in this context, is used in the sense of meaning "what remains after deductions" -- in this case, the deduction of any energy outflows from metered energy inflows. Under net metering, a system owner receives retail credit for at least a portion of the electricity they generate. The ideal has your existing electricity meter spinning backwards, effectively banking excess electricity production for future credit. In reality, the rules vary significantly by country and possibly state/province; if net metering is available, if and how long you can keep your banked credits, how much the credits are worth (retail/wholesale), etc. Lightning strikes during a night-time thunderstorm. ...

Net Metering is generally a consumer-based renewable energy incentive. While it is important to have Net Metering available for any consumer that interconnects their renewable generator to the grid, this form of renewable incentive places the burdens of pioneering renewable energy primarily upon fragmented consumers. Often over-burdened energy agencies are not providing incentives on a consistent basis and it is difficult for individuals to negotiate with large institutions to recover their Net Metering credits and/or rebates for using renewable energy.

Time of use net metering
- Further information: Smart meter
Time of use (TOU) net metering employs a specialized reversible meter that is programmed to value electricity at fixed values during different periods of the day, which may also vary with differing seasons. A Smart meter generally refers to a type of advanced meter (usually an electrical meter) that identifies consumption in more detail than a conventional meter, and optionally communicates that information via some network back to the local utility for monitoring and billing purposes. ...
This is available in California and is presumed to be highly favorable to smaller systems that displace the highest cost electricity and systems, where the user's demand load may be managed so that there is a net production of electricity during high cost periods. This can be done for example, by chilling water during off peak times for air conditioning use during high demand periods, or by pre-cooling the thermal mass of the building during low cost periods.

A hiccup has occurred in California legislation (SB1 - 2006), in that new (after Jan. 1, 2007) residential solar systems are singled out to be billed on TOU schedules, and at least one utility (Southern California Edison (SCE)) has rate structures which are punitive to the solar customer, particularly for smaller systems. This faulty legislation created a disincentive to new solar installations, and/or windfall profits to SCE.(This has since been remedied through legislation)
In North Carolina initial net metering rules were put in place in 2005 to prohibit systems that include backup battery power, however due to consumer feedback this restriction was lifted in July 2006.

Kansas Kansas does not have a consumer Net Metering incentive, but does have a renewable metering incentive on the wholesale level that provides the wholesale commerce of renewable energy at 150% of the avoided cost. Thus, the incentive one receives in this case is dependent not upon the price of retail electricity per kWh, but upon the price of wholesale electricity.

The Kansas Solar Electric Co~operatives [K-SEC] was founded January 2005 by Eileen M. Smith, M.Arch. VITAE as a non-profit and non-competitive renewable electricity cooperative. K-SEC Phase I Demonstration is structured around Kansas House Bill 2018 passed in 2003 by Kansas Representative Tom Sloan. See Kansas Statutes Annotated Chapter 17-4661 and 17-4655
The K-SEC program has the goal of installing 1,000 MWp building-integrated photo voltaic [BI-PV] solar electricity by 2018. This translates to approximately one hundred million SF of BI-PV solar roofing or one million SF BI-PV roofing in 100 of the 105 counties of Kansas. This will require 70,000 to 100,000 SF BI-PV per county per year for ten years. K-SEC will not sell the solar systems, but they are going to lease consumer rooftops in exchange for a high-tech battery back-up system for fifty years. K-SEC will manufacture, install, monitor, maintain and sell the electricity wholesale. K-SEC will provide numerous job opportunities to rural and urban Kansas communities from manufacturing to solar system design, installation, maintenance, monitoring and electricity sells. SF is a two-letter abbreviation which may refer to: // San Francisco, California, a city with a population of more than 730,000, located on the West Coast of the United States. ...
The foundational structure for the K-SEC Program is the Kansas Solar Electric Buildings Registry and GIS Database. A list is being compiled of Kansas homes and buildings that have unshaded roofing surface that could accommodate 100 SF to 50,000 SF of BI-PV solar materials. The rooftops must have south to southwest facing or flat rooftops.
The K-SEC Program is important for Kansas where 72.5% of the electricity Kansas presently consumes is generated by coal-fired power plants. In 2004 and 2005 projects totaling a 55% increase in coal-fired power plants were proposed in Kansas. Kansas Department of Health and Environment has already issued warnings not to eat the fish in Kansas rivers and lakes due to the extreme amount of toxic mercury from coal-fired power plant emissions. Coal-mercury toxins cause a variety of health hazards with the most serious being fetal damage and mental retardation in children.
Market rate net metering In market rate net metering systems the user's energy use is priced dynamically according to some function of wholesale electric prices. The users' meters are programmed remotely to calculate the value and are read remotely. Net metering applies such variable pricing to excess power produced by a qualifying systems.
Market rate metering systems will be implemented in California starting in 2006 and under the terms of California's net metering rules will be applicable to qualifying photovoltaic and wind systems. Under California law the payback for surplus electricity sent to the grid must be equal to the (variable, in this case) price charged at that time. It can never be negative, meaning you cannot make money from selling the electricity back. If you generate more electricity than you use then over a period of a month you will be billed zero and not make any money, in effect you give away your extra energy if you do not use it.
Net metering enables relatively small systems to result in zero annual net cost to the consumer provided that the consumer is able to shift demand loads to a lower price time, such as by chilling water at a low cost time for later use in air conditioning, or by charging a battery electric vehicle during off-peak times, while the electricity generated at peak demand time can be sent to the grid rather than used locally (see Vehicle-to-grid). No credit is given for annual surplus production. The Toyota RAV4 EV was powered by twenty-four 12 volt batteries, with an operational cost equivalent of over 165 miles per gallon at 2005 US gasoline prices. ...

Net purchase and sale Net purchase and sale is a different method of providing power to the electricity grid that does not offer the price symmetry of net metering, making this system a lot less profitable for home users of small renewable energy systems.
Under this arrangement, two uni-directional meters are installed—one records electricity drawn from the grid, and the other records excess electricity generated and fed back into the grid. The user pays retail rate for the electricity they use, and the power provider purchases their excess generation at its avoided cost (wholesale rate). There may be a significant difference between the retail rate the user pays and the power provider's avoided cost.[1]
Germany and Spain, on the other hand, have adopted a price schedule, or Feed-in Tariff (FIT), whereby customers get paid for any electricity they generate from renewable energy on their premises. The actual electricity being generated is counted on a separate meter, not just the surplus they feed back to the grid. In Germany, for the solar power generated, a feed-in tariff of more than 3 times the retail rate per kWh for residential customers is being paid in order to boost solar power (figure from 2006). Wind energy, in contrast, only receives around a third of the retail rate because the German system pays what each source costs. A Feed-in Tariff (FiT, FiL, Feed-in Law or Solar Premium) is a procurement mechanism designed to promote the uptake off renewable energy through government legislation. ...
Related technology Sources that produce direct current, such as solar panels must be coupled with an electrical inverter to convert the output to alternating current, for use with conventional appliances. The phase of the outgoing power must be synchronized with the grid, and a mechanism must be included to disconnect the feed in the event of grid failure. This is for safety - for example, workers repairing downed power lines must be protected from "downstream" sources, in addition to being disconnected from the main "upstream" distribution grid. Direct current (DC or continuous current) is the continuous flow of electricity through a conductor such as a wire from high to low potential. ...
