Most of these requirements take the form of a «renewable portfolio standard» (RPS) adopted by 26 states and the District of Columbia or «alternative energy portfolio standard» (AEPS) adopted by three states, which requires a certain percentage of a utility's power plant capacity or generation to come from renewable or alternative energy sources by a given date.

In the absence of nuclear power, maintaining sufficient electricity capacity will require strong policies to promote energy efficiency and renewable energy.

But it turns out that countries with far higher levels of so - called variable renewables are doing without capacity markets at all, finding that other measures are sufficient, such as investing in transmission capacity, reforming power markets and requiring renewable energy technologies themselves to play a bigger role in meeting power demand.

Wind and solar require expensive renewable energy plant, far flung networks of lossy transmission capacity, and equivalent levels of fossil fuel backup generation (usually operating very inefficiently).

In order to stay online, these reliable plants may require one or all of the following options for remedy: 1) further economic support to make up for losses in energy markets, 2) a new revenue stream from capacity markets, or 3) immediate termination of subsidies and mandates for renewables.

However, RPS does not work on installed capacity, it requires kWh delivered to be from renewables.

This is based on assumed annual demand growth of 6.34 %; further scenarios with higher growth rates and low addition of renewables capacity do require new coal stations, but still only at most half of those under construction.

Switching from immediate to intelligent PEV charging allowed for better alignment of renewable generation and load profiles, decreasing both the power and energy capacity of SES required to reach the RPS target.

According to India's draft national electricity plan, no new coal - fired stations will be required during 2017 — 22, with current capacity and projected renewables capacity sufficient to meet demand growth.

Additionally, intelligent charging can reduce the amount of renewable generation that needs to be shifted to meet electricity demand, which can reduce the required capacity of energy storage systems need to meet a renewable energy utilization target.

In the study, published in the Journal of Power Sources, the UC Irvine team examined how the intelligence of plug - in electric vehicle (PEV) integration impacted the required capacity of energy storage systems to meet renewable utilization targets for a large - scale energy system, using California as an example for meeting a 50 % and 80 % renewable portfolio standard (RPS) in 2030 and 2050.

The EPA will demand that conventional plants run at 70 % of capacity, even as the switch to «renewables» requires that they run at 25 %.

India's 2027 renewable energy target requires 57 % of installed capacity to come from non-thermal energy, necessitating 21 - 22 GW annual renewable installations.

But while India's power demand will double over the next decade, its draft National Electricity Plan (NEP) calls for rising demand to be met with 275 gigawatts (GW) total renewable energy capacity by 2027, without requiring new coal plants beyond those already under construction.

IEEFA finds India's wind and solar energy costs have fallen 50 % to as low as $ 38 per megawatt hour (MWh) over the past two years, with renewable energy bids in new auctions costing 20 % less than the cost of wholesale electricity from existing Indian coal generation, and 30 - 50 % less than the required cost to justify new imported coal or liquefied natural gas capacity.
