Extreme temperatures across the globe are putting extra strain on power grids, and energy analysts say storage could help balance struggling electric supply systems as the grid is modernized for today’s energy supplies and demand.
Very high heat in summer poses multiple challenges for energy grids. Air conditioning in individual homes, businesses and industrial facilities create a large and sudden draw on public power supplies, adding to normal daily demands. High temperatures also affect the power distribution system’s physical features. Power lines can sag in extreme heat, causing them to malfunction or pose a fire risk in dry landscapes. That same heat (or, in different seasons, extreme cold) can interrupt the delivery of fuel to power plants that generate electricity.
Blackouts and grid failures are now common risks, added to outages caused by natural disasters like hurricane, floods and wildfires. Modern households and businesses are heavily dependent on electricity for everything from cell phone charging to internet-based services to food storage, not to mention heating and cooling. A lot rides on a stable electrical supply, and energy experts say one key to stability is energy storage.
“As temperatures increase, grids will need to be more resilient, including storage to handle demand surges and supply disruptions,” energy experts report in a recent look at global power outages.
Storing grid energy, solar or wind energy in battery systems allows individuals and grids to ride out the surges in power demand more smoothly. Batteries can stockpile energy when demand is low — on a cool night when appliance use is idle — for use later, when demand for power is high, like during the hottest part of the hottest summer day. This is possible for individual homes, and works extremely well paired with solar panels. Many of our mtvSolar customers have enough panels to offset all of their daily electrical usage and charge up battery systems like the Tesla PowerWall for use during outages or brownouts. Other customers use battery systems alone, charging them from the grid to sustain their homes or businesses when power goes out.
