Grid Scale Energy Storage

A large portfolio of buildings in a grid-constrained metropolitan area becomes a significant energy resource.

Portfolio optimization provides aggregate benefits exceeding individual building benefits. Much like grid resources acting in concert to achieve economy and reliability, buildings within portfolios contain complimentary features and capabilities that QCo coordinates for synergistic effect.

From a smart grid perspective, QCo’s technology harnesses the inherent physical and operating flexibility of commercial buildings to create value for, and provide services to, the electric grid very quickly and at low cost.

“Free” thermal mass, on the multi-MW scale that already exists in large metropolitan areas, creates a national opportunity for:

  • Continuous demand elasticity – competing and dispatching against electric generation to moderate market prices (and price volatility) and reduce peak demand by creating price elasticity in large commercial office building electric demand that is continuous, dispatchable, and scalable.
  • Source and end-use efficiency – optimally timing the cooling and discharge of a building’s thermal mass i) to create generating unit commitment and dispatch economies; ii) to displace inefficient marginal generators in grid ancillary services markets; and iii) to improve the economics and penetration of high efficiency systems within buildings for the benefit of electric system source efficiency.
  • Reduction of power plant emissions (carbon, NOx, SO2, and particulate emissions) – similarly timing the cooling and discharge of a building’s thermal mass to also effect more rational and efficient day and night-time loading of generating plants for significant environmental benefit.
As QCo technology gains building and grid operator confidence, commercial buildings will create value in numerous grid markets and operations, from regulation to capacity to balancing.
