Electricity storage in a redesigned market

Storage technologies have the potential to significantly support the EU’s electricity system, bringing a number of flexibility services. There are numerous electric energy storage (EES) technologies, tackling different magnitudes in terms of quantity of energy, ramp-up time, duration of discharge, costs, and lifetime.

However, legislation around storage raises a number of challenges if analysed under the current unbundling rules involving a mix of regulated operators and market-based mechanisms. This stems partially from a non-inclusive definition of storage. The study provides an alternative definition which aims to capture the perspectives of multiple stakeholders. Furthermore, we discuss the need to value EES technologies such as batteries, pumped hydropower, flywheels, power-to-X, etc. based on their ability to provide different services. This is based on a techno-economic comparison of different EES technologies, given in additional tables. Finally, the study looks at how storage fits into the current regulatory system and proposes options for future systems so that EES are not discriminated against other flexibility options. A set of policy recommendations is provided that relates to the definition of storage, broadening ownership models, avoiding double grid fees, and valuing EES’ potential for supporting the EU’s 2030 energy and climate targets.

India is poised to remain the world’s fastest-growing major economy, and this rapid growth is driving a sharp rise in energy demand. As the most populous country on the planet, India urgently needs to decarbonize its energy systems.
Water in Mexico: an Emergency that Will Wait
Access to water is already and will become increasingly problematic for Mexican economic actors due to the progressive scarcity of the resource resulting from climate change, a geographical distribution that does not coincide with that of the population or economic activity, and management that has so far been far too lax.
AI, Data Centers and Energy Demand: Reassessing and Exploring the Trends
The information and communication technologies sector today accounts for 9% of global electricity consumption, data centers for 1-1.3%, and artificial intelligence (AI) for less than 0.2%. The growing energy demands of cloud services first, and now AI workloads (10% of today’s data centers electricity demand), have exacerbated this trend. In the future, hyperscale data centers will gain shares amongst all kinds of data centers and AI will probably account for around 20% of data centers electricity demand by 2030.
