b'The Growth of Energy StorageAND ITS IMPACT ON ELECTRICAL CONTRACTORST of renewables and bi-directional flows on the grid,What dose this mean for electrical contractors? began The world has seen remarkable changes in the electricity sector. Vast quantitiesWith growth in industry comes growth in jobs. alongwithrapidcostdeclinesandperformanceimprovements,"When solar energy started booming about ten years ago, it have allowed for several major deployments of energy storage.

"There is a opportunitiesforCanadianelectricalcontractorsinthenot-too- similar opportunity emerging around energy storage with its diversity distant future. in applications and scalability."Paul Luukkonen, emerging technologies consultant with Customized Energy Solutions, helps explain the growth of energy storage and what it means. While there is a diverse range of Energy storage is the capture of energy produced for future use. The energy can be stored in various ways, from pumped hydroelectric,energy storage technology types, the compressed air, flywheels and batteries to thermal energy storage."Energy storage is the only technology that can use energy generatedrapidly declining cost of advanced duringlow-cost,off-peakperiodstoserveloadduringexpensive on-peak hours," says Luukkonen. batteriesparticularly lithium-ion A core function is to store energy when supply exceeds load and inject energy when load exceeds supply.
