Flexibility Solutions for High-Renewable Energy Systems<\/em>, a new pair of reports published today by BloombergNEF in partnership with Statkraft and Eaton, explores the possibilities for solving the power system flexibility challenge in the U.K. and Germany. <\/p>\n

<\/p>\n

The studies analyse the potential contributions of energy storage, demand response, flexible electric vehicle charging and interconnections to Nordic hydro in enabling the renewable energy transition.<\/p>\n

New forms of flexibility are key to an affordable, renewables-led power system. Without energy storage, smart-charging electric vehicles, demand response and interconnectors, the energy transition risks proceeding on a suboptimal path, with a power system reliant on fossil backup and oversized renewables capacity that will come at a higher cost.<\/p>\n

Building on BloombergNEF’s flagship forecast for the global electricity system, the New Energy Outlook (NEO), this study explores alternative futures for the power system, depending on how each flexibility technology might develop in the coming years. It uses BNEF’s proprietary New Energy Outlook modelling tools, meaning that every scenario is, for the given assumptions, a least-cost optimal solution. Each scenario starts with different underlying assumptions about what each technology can provide, and\/or at what cost.<\/p>\n

We find that, in general, flexible technologies help integrate large volumes of renewable generation by shifting excess demand to periods of high renewable generation, or by storing the excess renewable generation for periods of high demand. This comes with important benefits in terms of system costs and carbon emissions.<\/p>\n

However, while in the U.K. new sources of flexibility mainly help to displace fossil backup capacity, that is not always the case in Germany, where flexibility can support cheap, inflexible coal generation in some scenarios. This highlights the importance of addressing coal generation in Germany through policy action, to ensure a low-carbon transition.<\/p>\n

Our analysis shows a need for new sources of flexibility in both the near and long term across scenarios:<\/strong><\/p>\n
