Sentences with phrase «peak load plants»

Peak load plants which can cope with short term variation and respond in minutes.

Not exact matches

When energy use approaches peak loads (where the less efficient power plants come online), they start taking action.

(note there is some energy demand management that is is / has been already used to reduce the need for peak power supply; I don't know offhand how much there is and what it would look like if this were simply reshifted to reduce the need for backup power supply, which would be like peaking and load - following plants now.

In June I heard a report about a new EU - wide study done in the UK that showed clearly that by combining all forms of renewables: wind all over Europe, solar in North Africa, hydo, hydro storage, solar thermal, and demand management, you could meet a slowly growing EU load with almost no natural gas for peaking plants to help level the load.

In the two years since the nuclear moratorium, the nation has urgently needed new baseload power plants to shoulder the country's annual peak load of 80 GW.

This is particularly relevant for power systems where the peak load is expected to increase at the same time as conventional power plants to be replaced by intermittent renewable power generation.

Concentrated Solar Power (CSP) can be a night - only dispatchable (D - CSP) plant; with its entire solar energy absorbed by day to be delivered after dark to cover the evening peak load on the grid, according to a study funded by the US Department of Energy (DOE).

The call for tenders specifies the total amount of capacity required, the time lines for capacity establishment, the fuel options as defined in the Government's power plant establishment plan, the type of plant (base load, load following, peaking capacity), possible transmission constraints that have to be taken into account, and in certain cases a price cap, i.e. maximum average price that the new plant can be expected to earn throughout its economic life.

Adding wind and solar photovoltaic capacity to the grid may require augmenting the amount of peak - load plants, which can be done relatively cheaply by adding gas turbines, which can be fueled by sustainably - produced biofuels or natural gas.

If an Electric Utility built a nuclear power plant to meet this peaking load, the capacity factor of the nuclear plant would be very low (25 %).

In the new system, rather than having «always - on» baseload (e.g. nuclear) plants, and then following any extra load with peaking plants (usually gas), in the new system, variable loads and variable supply (from renewables) are balanced via a smart grid with demand - side measures, load peak shaving / delay, energy storage, and backup sources.

Wind power and solar energy, because of their intermittency and unpredictability, require back - up generation, especially during peak - load capacity, and that has generally entailed the construction of natural - gas plants.

Then there's «intermediate load,» with the next - cheapest tier of power plants, and at the top of that second hump, «peak load,» satisfied by (usually natural gas) «peaker plants» that are expensive to run but easy to ramp up and down quickly.

Previously, solar power plants had depended on back up energy plants powered by carbon emitting fuels because a solar system's peak generation hours do not coincide with the utility's peak load hours after 5 p.m. Low sunlight meant low energy generation, and this challenge scaled back the environmental benefits of solar plants.

The duck curve shows a major drop in electric load in midday when solar hits its peak, swamping the grid at a period of low demand and potentially pushing net load below the point where older baseload plants can ramp down to compensate.

Owing to their lower capital costs but higher fuel costs, natural gas technologies, including combined - cycle and turbine plants, were designed to meet intermediate and peak electrical load.

That means all the peaker plants get shut down, all the intermediate plants get shut down, and some of the base load plants start to get ramped down too.

If electricity was dynamically priced, price fluctuations would be arbitraged by those market participants who could shift their demand or supply at least cost; among other things, this would remove the need for expensive peak - load plants and make solar and wind energy much more practical.

Coal plants operating between their peak and minimum values can provide load following capability to the system.

While the need for nuclear power is absolutely critical in meeting our base load requirements (and reducing CO2 emissions, and reducing fuel risk by having a diversified generation portfolio of power plants)-- peaking load and generation options to meet this load (which solar currently fits into) is important also.

Pumped - storage hydroelectric plant: A plant that usually generates electric energy during peak load periods by using water previously pumped into an elevated storage reservoir during off - peak periods when excess generating capacity is available to do so.

Peak load month: The month of greatest plant electrical generation during the winter heating season (Oct - Mar) and summer cooling season (Apr - Sept), respectively.

To follow the variable demand the power producers use a variety of «building blocks» from steady running constant load units (Nuclear, Hydroelectric) to slow load - following power plants (Gas & Coal boilers) to rapid start high demand units (Combined Cycle Gas Units) to peaking units (Gas & Diesel generators).

Worse, nuke plants require water for cooling and would be shutdown in summer drought just when the AC load peaks.

SB 338 requires the California Public Utilities Commission (CPUC) and all other locally owned utilities to start planning to meet their net - load peak energy and reliability needs with alternatives to fossil - fuel generating plants, while also providing the electricity at the lowest cost to consumers.
