Ørsted lines up first major UK battery storage project

Energy firm Ørsted has announced its first venture into large-scale energy storage systems, after announcing plans to build and operate a 20MW battery storage project near Liverpool. EURACTIV’s media partners edie.net reports.

The Carnegie Road battery storage project is expected to become operational by the end of 2018 and will serve the UK’s national grid in managing grid stability. NEC Energy Solutions will supply the battery system and construction is expected to start in May.

Ørsted’s head of energy storage and solar Ryan O’Keefe said: “We’re excited to develop this project. As batteries have a very high frequency response capability we believe they’ll play an important role in providing services for the support of the stability of the power grid.

“The demand for these services is likely to grow in the UK as the country is expected to decommission large parts of its carbon-based generation fleet and introduce more renewables generation.”

Energy transition

The Danish firm, formerly known as DONG Energy, is transitioning from an oil and gas major into a low-carbon energy provider. As well as pledging to phase out coal from its heat and power generation by 2023, Ørsted has spearheaded the development the world’s largest offshore wind farm, Hornsea Project One, off the coast of Yorkshire.

Last year, the company revealed plans to integrate small-scale battery support into the Burbo Bank offshore windfarm. The 2MW battery gives the 90MW Burbo Bank windfarm the ability to inject or reduce bursts of active power being sent to the National Grid.

Ørsted is building up a global portfolio of energy storage projects. Alongside the EnergyLab Nordhavn project in Denmark, the company has announced intentions to set up a 1MW storage pilot in Taiwan and 55MW storage connection to the US Bay State Wind project.

“The future energy system will be completely transformed from what it is today, with a smarter, more flexible grid, balancing supply and demand with new technology and cleaner energy generation. We want to continue to be at the forefront of this exciting shift towards a decarbonised energy system,” Ørsted UK’s managing director Matthew Wright added.

The UK project, originally developed by Shaw Energi, could spark a storage boon for UK energy companies. British Gas’s parent company Centrica could have a near-50MW storage project online this year, while power station operator Drax plans to complement its ongoing biomass conversions with gas and battery storage options at two coal power units.

Storage ‘not fundamentally needed’ for future power grid, scientists say

The emergence of household batteries, along with small-scale solar photovoltaic and plug-in electric cars, is slated to transform electricity storage, according to a new state-of-the-art report by European science academies. But experts claim storage is not actually fundamentally needed.

A European Commission proposal for a new EU electricity market design was unveiled on 30 November  2016 as part of a Clean Energy Package of legislation.

The goal is to create a market fit for a growing share of power from intermittent renewable sources, chiefly wind and solar.

One area that looks set for rapid growth on the back of these changes is battery storage, which could enable consumers to buy electricity when it is going cheap, and use it later when peak demand pushes prices up. Storage capacity may also come in the guise of electric vehicles connected to the grid.

European power grid on cusp of storage revolution

An electricity market revamp could see battery storage go mainstream. But questions remain over who will put the infrastructure in place.
