Or they may increase the efficiency of the grid by consuming off-peak load and pushing more kilowatt-hours over the same infrastructure.
FORBES: On The Verge of Change: A View of Our Future Energy World
We think that the solar array along with batteries will carry a lot of the peak load and mitigate that problem.
The main objective of smart power meters is to lower the peak load and thus enable utilities to keep down their peak generating capacity.
ECONOMIST: Utilities are getting wise to smart meters and grids
"Residential air-conditioning is the peak load problem, and we're able to tackle the load-shifting in a very automated way, " says Matt Rogers, Nest's engineering VP.
Since John is still doing his laundry during peak load hours, the utility is paying top dollar in infrastructure costs and high-cost backup power plants.
FORBES: How The Smart Grid Fell From Grace And What To Do About It
Home appliances, meters, transformers and generators could all share data and work together to make the power grid more efficient, for example by lowering the peak load.
That is why regulators in each country must ensure that there is enough spare generating capacity boffins say perhaps 20% above expected peak load and transmission capacity to be sure the lights stay on.
Ask any engineering executive at any car company: In order to meet new and ambitious fuel-economy standards in the global markets including a U.S. Corporate Average Fuel Economy standard of 54.5 mpg by 2025 cars and trucks of the near future will have to exploit the advantages of electric drive (low rpm torque, low-speed efficiency, regenerative braking) in urban driving, while reserving the gasoline-fired engine for times of peak load and sustained demand.
Electrical utilities need to ensure this daytime peak demand load does not exceed their supply capacity.
With a large build out of solar and wind the peak power load can be reduced because of the onsite usage of the power.
FORBES: More False Hope About Renewable Energies That Consumers Reject
Advances in fuel cell technologies are critical in supporting the integrated grid systems, with their peak-load management and mitigation capabilities, and without which integrating renewables into the energy mix will be a much more expensive and painful affair than often supposed.
FORBES: Why "Green Fossils" Matter So Much To Africa's Energy Future
Only by load-shedding can enough be kept back for peak use through the winter.
Whereas previous studies suggested the cadmium load was highest in the 1960s and 1970s, the new research shows the peak input occurred decades earlier.
That is well above the base power load and the surge is supplied by less efficient fossil fuel power generators as well as some peak pumped water storage.
