Centrica Energy has engaged Younicos and Morrison Utility Services to deliver one of the world’s largest battery storage facilities at Roosecote, Barrow in Furness. The 49Mw facility will be built between March 2017 and Spring 2018. Once operational it will respond to fluctuations in energy demand in under a second and be capable of meeting the power needs of around 50,000 homes.

Build will require use of local and specialist suppliers. On the 27th February Centrica held an initial supplier briefing. Morrison Utility Services explained that this project may need a good range of new suppliers due to its location well away from where its Framework Contractors are located. The company explained  it may need the following supplies:

  • major civil works
  • electrical building services installation
  • mechanical installation
  • building construction, including steel erection and cladding
  • haulage
  • logistics movement of transformers and specialist battery equipment
  • aggregate and concrete supplies
  • security guarding
  • fencing
  • accommodation in hotels/catering
  • cleaning

Up to 100 personnel will be involved in the build process and will need accommodation locally.

The Developer is Centrica Distributed Generation Limited .              The project is a 49MWe gas-fired energy reserve facility.                 The (Battery) Enhanced Frequency Response (EFR) facility is to be sited adjacent to a possible future 50MW power generation site.

The purpose of the proposed development is to charge the housed batteries via the cables from the national grid storing energy which can then be released at other times in order to stabilise the frequency of the grid or provide energy during periods of electricity shortages

 The energy storage facility will have an output of up to 49.9MWe (likely at least 20MWe) and a 1.1.3storage capacity of up to around 50MWh.

Using batteries, the proposed EFR could store up to 44MWh of energy from the grid for a short period of time, offering a highly flexible on-demand response to help stabilise the local distribution network. The primary function of the battery facility will be to ensure consistent frequency control of the electricity network by importing and exporting power as required by National Grid. The new facility will complement the existing electricity network in the area by providing fast response capabilities to support the network.

The proposed development is similar to a small warehouse building and will contain 1.1.2lithium-ion batteries in racks and with heating, ventilation and air conditioning (HVAC) to maintain optimum temperatures, which will be provided within an acoustic enclosure on the roof.It is proposed to be situated to the south west of the Proposed Development Site and is understood to predominantly comprise of a single building measuring 25.8m x 28.7mwith a height of approximately 11m.

The application will be connected via a cable to the existing Electricity Northwest 132kV substation to the north.

At this stage the technology provider has not been finalised. Consequently, to provide the necessary flexibility to enable all potential technology providers to be accommodated, the built form contained within this Application are based upon the worst case maximum design parameters that may be required

The Battery facility comprises the following main parts:

  • Two-storey battery enclosure building;
  • External access stairways;
  • HVAC plant within acoustic enclosure;
  • 3 no. parking spaces
  • 4m wide access track around the building
  • New access road around the building
  • Security perimeter fence.
  • A new 132/11kV oil filled transformer with 9m concrete blast wall surround sited in the north west corner of the site. It will have a high side voltage of 132kV and a low side voltage of 11kV.

Externally, the application will comprise of a warehouse style unit two storeys in height, with access stairways and HVAC plant located within an acoustics enclosure on the roof to reduce noise. Internally, the facility will comprise battery racks, a switch room and control room, welfare space for maintenance visitors, WC and goods lift which will provide access to the first floor of the unit only and will not provide access to the external roof space. The internal area will be accessed by four external doors at ground floor level; four external doors at first floor level and stairways on the outer extent of the building to allow access to the external roof space.

As the facility will be unmanned, permanent operational lighting is not required. The facility will require the provision of some lighting for security and maintenance purposes when engineers are working on site in low light.

In addition to the 3m high security fence, a closed circuit television (CCTV) system shall be provided to monitor the Plant perimeter fence for intruders and also provide coverage within the main plant areas. Weatherproof pan/tilt/zoom (PTZ) colour cameras with IR night mode in low lux levels shall be provided to cover all areas.


A small number of specialist suppliers will likely be involved. Battery facility contractors are likely to be specialist providers.

Supply chain discussions have taken place on the basis of:

  • Supplier potential to support the build and operations/maintenance of the  investment;
  • Opportunities to service major developments with similar energy sources with Centrica Energy providing MW generation and/or battery storage;
  • The construction of the Proposed Development will directly support approximately 100 workers for 12 to 15 months. Indirectly, the construction of the Proposed Development could potentially also generate employment opportunities within the local supply chain for those companies providing services to the Proposed Development, for example engineering and maintenance services, plant and equipment supply and haulage. Once operational the Proposed Development, in conjunction with other similar developments, will provide up to two part time jobs for operation and maintenance of the facility.

Other project on site may come later: A 50MW power station

A 50MW power station may be constructed on an adjoining 0.6 hectare site, build time 15 months. It will be unstaffed and automated  and maintenance needs may be a contract opportunity.

Planning applications are now submitted the planning statement is viewable at Planning Statement – Roosecote Energy Storage WSP | Parsons Brinckerhoff Centrica Project No: 70020933 May 2016 planning app b12/2016/0354, see http://www.barrowbc.gov.uk/papps/temp_blobs/PLAN_2016_0372_ADDITIONAL_12.pdf  with WSP | PARSONS BRINCKERHOFF assisting with that process.

The 50 MW gas-fired energy reserve facility to support the provision of power demand on the local distribution network during peak periods.

The Proposed Development will be predominantly housed within one main engine hall which could have a maximum footprint of 54m x 28m with a maximum building height of 14m. Attached to the engine hall could be up to five stacks, up to 30m in height. At this stage the technology provider has not been finalised.

The gas-fired energy reserve facility will provide energy security with sufficient capacity to serve the equivalent of up to 50,000 homes within the local distribution network

Unlike a traditional power station, the engines would be operated as a highly flexible ‘peaking plant’ meaning that they can quickly respond to peaks in energy demand. The facility will be able to reach full load in less than five minutes from cold and, after only a few hours of operation, will power down completely.. The plant will not be used for base load operation, being limited to just 1,500 hours running per year.

Typically, the station would be switched off, waiting for an instruction via National Grid to power-up. These instructions could come as a result of system instability or peaks in demand which would require generation support from the facility for between 1-7 hours per day, between 8am-8pm, typically on weekdays. During the winter ‘peak’ periods (November-February), the facility may generate to reduce stress on the electricity transmission system; historically, these peaks last for up to 3 hours, between 4.30-7.30pm. Outside of these hours, such as during a major power shortage or system stress event, National Grid may require the facility to step-in
