Request for Proposals: A Techno-Economic Evaluation of Transportable Energy Storage
With increasing use of renewable energy sources there are many cases where the generation sites are not within easy reach of the homes and businesses that need the electricity.
For example, offshore wind-farms are inevitably further from major conurbations than existing coal-fired power stations. In this situation, how the energy is moved from where it is generated to where it is needed becomes a more critical aspect of the overall energy system.
More remote locations are more costly, and difficult to connect to transmission lines, be they electricity networks or pipelines. At the same time the intermittency of renewable energy sources places a greater emphasis on the use of energy storage to balance supply and demand for electricity.
Transporting stored energy is one possible way to address both of these concerns simultaneously.
In deciding whether to support the development of transportable energy storage technologies, the ETI needs access to a thoughtful and factual analysis that considers all the relevant factors and identifies where transportable energy storage is most likely to be beneficial and at what cost the development of potential technologies could deliver transmission scale transportable storage.
This project will be successful if it enables:
• An assessment of the potential economics and contribution of energy storage and transportation as part of a future UK energy system.
• Identification of the most promising technologies and their development requirements.
• Identification of potential situations most suited to the use of transportable energy storage and, if possible, recommendation of locations and scope for the next stage of technology development and demonstration.
The study will provide information to the ETI as to the relative merits of transportable energy storage and the potential to move forward to a demonstration project.

Request for Proposals: Development, Test and Demonstration of Distribution Scale Electricity Storage Technology
Click here to view the press release
The ETI is seeking organisations capable of taking part in at least one project to design, build and demonstrate, in a realistic environment, an energy storage technology which could play a crucial role in delivering affordable, secure and sustainable energy systems in the future.
The project will see the device development, building, commissioning and operation of an energy storage device of sufficient capacity that it can deliver at least 500kW on an 11kV distribution network for approximately four hours. This is enough stored energy to power around 400 homes for four hours in the winter and will be needed as an important element of the local electricity networks to keep the lights on when renewable generators are not able to operate, for example, due to calm weather with no wind.
The first stage will be to seek technology proposals ahead of a shortlist being developed into full project proposals. The intention is for the ETI to then select at least one of the full project proposals and commission the development and building of the electricity storage device.
Once built the device will be tested and commissioned on an operational 11kV distribution site under real conditions to ensure its effectiveness and reliability. It is envisaged that the device will be demonstrated under realistic conditions for at least a year.
The deadline for submitting an intention to bid is 2 September 2010
The closing date for bid submission is 24 September 2010
