Load Flexibility Valuation Is Critical to Grid Reliability
The energy industry is undergoing a foundational and necessary transition away from fossil fuels. The growth of variable renewable energy sources has increased supply-side volatility resulting in new net load shapes. Jurisdictions around the world are implementing aggressive clean energy targets and emissions reductions goals along with new market regulations for distributed energy resources (DER). The transportation and buildings sectors are increasingly electrifying end uses that once relied on fossil fuels, and advancements in digitalization are being used in the energy sector to improve operations.
As a result, load flexibility has been exposed as a valuable grid resource in the path to achieving zero emissions in the energy sector. Load flexibility plays a critical role in maintaining grid stability by reducing strain on the grid and allowing for continued reliable operation as the supply-side landscape trends toward renewables. To ensure load flexibility reaches its true potential and the grid remains balanced, load flexibility must be accurately valued in energy markets. Accurate valuation of load flexibility is expected to lead to fair competition with traditional generation sources as well as innovation.
This Guidehouse Insights report discusses the ongoing shift in the energy industry from fossil fuel sources to renewable sources, its impact on grid operations, and the ways in which load flexibility can address that impact. The report provides a formal definition for load flexibility and recommendations to key stakeholders for incorporating and valuing load flexibility in their portfolios.
