Curtailing wind and solar is not necessarily a bad thing as it may enable larger shares of renewables through making them flexible. Although a moderate amount of curtailed energy can be tolerated, huge amounts of wasted energy from near-zero operating cost renewable energy sources would be inefficient and unprofitable.
Solving the variability problem of solar and wind energy requires reimagining how to power our world, moving from a grid where fossil fuel plants are turned on and off in step with energy needs to one that converts fluctuating energy sources into a continuous power supply.
The more solar and wind plants the world installs to wean grids off fossil fuels, the more urgently it needs mature, cost-effective technologies that can cover many locations and store energy for at least eight hours and up to weeks at a time.
Surplus energy can be caused by local constraints, leading to curtailments at some parts of the system before system-wide limits. Building transmission helps export the supply to high-demand areas. Options to reduce surplus energy are: output reduction of conventional power plants, export to other areas, demand side management, and energy storage.
Our solar power systems and energy storage products are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
