The European Commission says more interconnections between countries can reduce the need for investment in
peak generation capacity and cut generation costs, saving consumers between 12 and 40 billion euros by 2030.
Efficiency can also improve system reliability and allow utilities to reduce or manage the demand on their systems — in some cases offsetting the need to add new
peak generation capacity.
Not exact matches
The Ghana Grid Company Limited (GRIDCo) has announced that the country will enjoy stable power supply in the coming weeks as Ghana's electricity
generation capacity now exceeds demand at
peak periods.
In the California Independent System Operator's (CAISO) Summer Loads & Resource Assessment, CAISO noted that the
generation supply was expected to be adequate in order to meet
peak electrical demand requirements in spite of drought - related concerns, in part because of recent renewable and natural gas
capacity additions.
Researchers found, in the Midwest and East, there is sufficient off -
peak generation, transmission and distribution
capacity to provide for all of today's vehicles if they ran on batteries.
In South Australia, for example, a figure of 3 per cent of installed wind
capacity is used to represent the contribution to overall
generation supply at times of
peak demand; 8 per cent is used in Victoria.
Lastly, in a grid with 100 % renewable power production, the
generation capacity would need to be ten times larger than the
peak load, and excess electricity would surpass the EU annual electricity consumption.
In the case of a grid with 80 % renewables, the
generation capacity needs to be six times larger than the
peak load, while the excess electricity would be equal to 60 % of the EU's current annual electricity consumption.
But if the grid goes another direction — relying more on large and expensive
generation plants, for example — storage would make it easier to manage
peak demand without surplus
capacity.
Some details that would apply to California would be to rework geothermal fields for greater
peak capacity and lower off
peak / high wind
generation.
(F) Megawatts from a demonstrated and assured minimum of distributed solar electric
generation capacity in instances where
peak period and
peak demand conditions are directly related to solar radiation and accompanying heat.
It allows renewable sources such as wind and solar power to operate at full
capacity during
peak generation periods by storing excess energy until it is needed to meet later demand.
But as even more solar
generation is built, sunny daytimes will become off -
peak, and it will be the baseload plants that are no longer economical to run, while some dispatchable
capacity is still required to handle nighttimes and February.
Okay, it's ridiculous to compare a 40 - megawatt solar PV park to a coal - fired power plant that could crank out 4,000 megawatts at
peak capacity, but the fact Ontario Power
Generation (OPG) got a contract today to build such a solar project at the old Nanticoke Generating Station is, at the very least, symbolically significant.
Smart charging reduces the power difference between load and
generation during
peak curtailment, therefore reducing the power
capacity of SES required compared to immediate charging.
Combining wind with the large amounts of solar
generation expected to be added to the Queensland grid, will allow a higher penetration of renewable energy at lower costs while reducing the need for storage and other
peaking capacity across the network.»
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.
In solar, production is only 10 % of
capacity (
peak production only occurs at best 15 % of each day), and is produced far from the place of use, so it requires huge investment in plant and backup
generation, plus in dedicated transmission lines (which experience high energy loss in transmission).
Generally the solar they sell is
peak rate power — generated when it is most needed, thus it doesn't impact on baseload power
generation, but what it does do is reduce the need for far more expensive and carbon producing
capacity to sit idle during off
peak periods.
To ensure that supply always meets demand, a renewable power grid needs an oversized power
generation and transmission
capacity of up to ten times the
peak demand.
The amount that generating
capacity exceeds
peak demand, known as the «
capacity margin», is already shrinking in the UK, as older power stations are decommissioned without new
generation being created at the same rate.
Hence, this implies that the greater the electricity consumption
peaks, the larger the
capacity for
generation from natural gas plants must be and, consequently, the longer and larger the
capacity needed on stand - by status.»
With coal
generation set to
peak, there is no need for further coal
capacity, whilst on the supply side, there is the potential for China to become a net exporter of coal again.
For the 2020 Medium scenario the countries studied showed an average annual wind
capacity factor of 23 — 25 %, rising to 30 — 40 %, when considering power production during the 100 highest
peak load situations — in almost all the cases studied, it was found that wind
generation produces more than average during
peak load hours.
