The International Energy Agency's (IEA) energy storage technology roadmap aims to increase understanding among a range of stakeholders of the applications that electricity and thermal energy storage technologies can be used for at different locations in the energy system. Emphasis is placed on storage technologies that are connected to a larger energy system (e.g. electricity grid), while a smaller portion of the discussion focuses on off-grid storage applications. This focus is complemented by a discussion of the existing technology, policy, and economic barriers that hinder energy storage deployment. Specific actions that can be taken to remove these obstacles are identified for key energy system stakeholder groups.
ENTSO-E has asked EASE to provide insights on a CBA for storage projects in order to be able to integrate storage projects next to transmission projects in the CBA of the TYNDP. The focus of this document is on energy storage projects that are reaching the threshold size of 225 MW. Any electricity storage connected at the distribution level and medium-sized electricity storage connected at the transmission level is thus excluded from the scope of this document.
This report, developed by the THINK! project, analyses whether the benefits that electricity storage can provide are already recognised and valorised by the existing market design and regulation.
This document was requested by the European Parliament's Committee on Industry, Research and Energy (ITRE) and aims to identify the energy network infrastructures needed to cope with the increasing share of renewable energies. The analysis covers a timeframe up to 2050 taking into account different existing projections of renewable energy development. Published infrastructure development priorities as well as methodologies including notably infrastructure cost benefit analyses are critically assessed. It furthermore analyses the relationship between the promotion of renewable energy generation and related infrastructure on the one hand, and other (energy) policy goals and existing legislation at EU level on the other. Obstacles to grid-roll out are identified and policy recommendations are proposed.
Written for decision makers, this guide sheds light on managing power systems with large shares of variable renewables. It presents a new, step-by-step approach developed by the IEA to assess the flexibility of power systems, which identifies the already present resources that could help meet the twin challenges of variability and uncertainty.
