Demand response (DR) measures reduce or shift energy consumption during periods of
high demand on the grid.
Not exact matches
But conditions don't seem nearly as ripe for approving such investments and infrastructure in more crowded regions, where
demand for electricity is
highest, according to Matt Wald's latest article
on wind and the
grid.
Higher PV output at this time of day is often beneficial to
grid operators working to increase electric supply to balance
high levels of
demand, but customers generally will not see this benefit unless they are
on time - of - use electric rates.
The system produces more than enough electricity to power Ad Astra's labs
on a daily basis, and excess electricity is stored
on ICE's power
grid for later use in experiments with
high demand.
The utilities have been agitating against solar PV because it is reducing
demand on the
grid, particularly in daytime hours when generators could normally generate
higher revenues from increased
demand.
New research suggests that although global warming will lower
demand in some places in winter, in
high summer
on the hottest days the
demand for air conditioning could at times be so great that the electricity supply
grid would not cope.
(2) the goal described in paragraph (1) can be met or exceeded by lessening the difference between the periods of lowest and
highest electricity
demand, with particular focus
on reducing the frequency and severity of peak
demand periods, using smart
grid and
demand response technologies, practices, and activities, including --
Parker Gallant and Scott Luft have both looked at the report from the Independent Electricity System Operator or IESO, and found that not only was
demand at an all - time low that month (the lowest since the IESO began keeping records) but also that curtailed wind power (power we pay the wind power developers for, but do not accept
on the
grid because it isn't needed) was at an all - time
high.
One question that would remain to be addressed in the future is that of very
high rates of solar power
on the
grid, and how PG&E and the California
grid (Cal ISO) would manage the peaks and valleys of electricity production and
demand.
Otherwise we may have to curtail, and waste, valuable output from some of our wind farms when the wind is
high, but
demand is low - especially if there is also a lot of inflexible nuclear
on the
grid.
With the
higher energy
demands of the computer, I doubt this will make you independent of the power
grid, but wouldn't it be nice if you could get just enough charge to pick up your emails when you are
on tour?
High levels of renewable generation also make
demands on the existing
grid —
demands that it was not designed to cope with, such as transporting large amounts of wind power within a country, or coping with — as in Germany — big numbers of solar modules all feeding current into the
grid (most likely the distribution
grid, which was not designed for two - way traffic).
Energy storage can save power generated from clean energy systems such as solar, wind and combined heat and power (CHP) for later use, enabling buildings to reduce their reliance
on the power
grid during peak
demand periods when electricity rates are the
highest.
TOU rates, which charge
higher prices for electricity during periods of
higher demand, encourage customers to adjust their consumption to reduce strain
on the electric
grid.
That's because computerized controls in one's home and
on appliances can be set to respond to signals from energy providers to minimize electricity consumption at times when the power
grid is under stress from
high demand.
