"Peak demand" refers to the highest level of electricity or energy consumption within a specific period. It is the time when the most amount of energy is needed to meet the demands of consumers.
Full definition
A utility could fully charge vehicles when solar is plentiful, for example, and then limit charging during periods
of peak demand for electricity.
Demand response is the commitment of electricity users to curb consumption when necessary
during peak demand times.
During this shift, the buffer between
peak demand for power and the maximum that can be generated (the capacity margin) is expected to shrink.
The electricity from the coal - fired power plant will be utilized during the high
peak demand periods of the summer season to ensure security of supply at a reasonable cost.
The battery system allows for
reduced peak demand, off peak storage, renewable generation with excess being stores as hot water.
In general, bids from power plants, renewable energy and other resources need to cover their costs for being ready to meet
peak demand on an as - needed basis.
That's partly why it's overseeing the introduction of number of new schemes to match supply
with peak demand, such as the capacity market.
Smart - grid technologies could reduce overall electricity consumption by 6 percent and
peak demand by as much as 27 percent.
Wind output during the summer months frequently coincides with the afternoon and evening
peak demand hours, but it is also an intermittent resource and therefore has a limited ability to provide firm capacity.
-- The term «demand reduction» means the reduction in annual
peak demand as compared to a previous baseline year or period, expressed in megawatts.
Summer peak demand days generally coincides with high generation from solar power systems, as skies are usually clear at the time.
Further, the majority of countries will see a shift of temperature - driven annual
peak demand from winter to summer by the end of this century.
Another key challenge will be to deliver electricity where and when it is most needed, for instance during the early
evening peak demand period.
The smart thermostat will help people save even more money and help utilities curb
peak demand loads.
It might take a bit of demand management to
handle peak demand periods, but it's pretty doable.
The more we invest in solar, the
more peak demand at noon time will be wiped out, which will affect our gas turbines.
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.
For instance, a reserve margin of 15 % means that an electric system has excess capacity in the amount of 15 % of
expected peak demand.
We could hope that this type of scenario would never happen in a country
where peak demand is in the height of summer.
This varies by season and location, but generally
peak demand occurs just after sunset, when the sun is not shining.
A majority of fund managers responding to the survey also
anticipate peak demand for oil and gas to impact stock values within the next ten years.
Firstly, a requirement for policy to target the growth in
peak demand via time of supply feed - in tariff for small generation units.
And the vegetation can keep the roof cooler in summer, lowering interior air - conditioning costs and
therefore peak demand on area power plants.
In fact, around one quarter of retail electricity bills go towards meeting around 40 hours of
critical peak demand each year.
A stand - alone solar system without battery storage might not be able to
shrink peak demand — because, for example, demand could still be high on a cloudy day.
Perhaps we need to move to a system where most of the charge to consumers is based on
net peak demand or something similar?
Wind generators operate at 28 % capacity factor but have only 11 % availability at
peak demand due to lower wind output in the summer.
When wind turbines operate at lower capacity levels
during peak demand times, other suppliers such as gas plants are called on for what is needed to meet demand.
The utility wants customers to help
with peak demand but they may buy batteries instead of more grid power.
Then
at peak demand times, the ice or cold water is used to cool air for large office or industrial buildings, meaning they need much less power from the grid.
An approach being researched by the content delivery network provider helps reduce the grid - connected load during
peak demand periods, when electricity is most expensive.
ERCOT is expecting another 387 MW of additional utility - scale solar to come online by summer, and given the higher peak capacity contribution this will be the largest contributor to meeting
peak demand in the next four months.
