Battery Energy Storage System

Eclipse Power Networks were appointed by Sembcorp Energy UK (Formally UK Power Reserve) as the Independent Distribution Network Operator (IDNO) for the 50MW Battery Energy Storage System Site (BESS) at Cowstead in Sheerness, Kent.

Cowstead Battery Storage

The battery energy storage site is connected directly to the UKPN network via their existing 132kV Overhead Line (OHL) Network. A new UKPN 132kV disconnector was required to be installed beneath the OHL Point of Connection (PoC) as part of the contestable works.

Eclipse Power adopted the 132kV cable from the new disconnector to the 132kV metered Point of Supply (PoS).

An IDNO 132kV substation, incorporating 132kV earth switches, disconnector and dead tank circuit breaker, completed the IDNO adopted network assets that feed a client adopted 132/33kV 40/50MVA ONAN/ONAF transformer and 33kV GIS substation adjacent to the IDNO compound.

The Sembcorp network assets facilitate their 50MW BESS assets, which nearly doubles their UK battery storage portfolio.

Battery Energy Storage System

Project Challenges

The project had consent challenges which Eclipse helped to resolve quickly and efficiently. Such challenges are unlikely to have been resolved as efficiently, had the client elected to use the DNO to adopt the Contestable Works.

What is an IDNO?

Independent Distribution Network Operators (IDNOs) are OFGEM licensed companies that develop, design, own, operate and maintain local electricity distribution systems within the DNO network.

IDNOs are connected to Distribution Network Operators (DNOs), either directly, or through other IDNOs. They carry power to homes and businesses around Britain. Unlike DNOs, they’re not bound to any specific geographical region and can therefore offer their services to a wider range of customers.

A Recent Wind Farm Maintenance Project Application

Swalek’s wind farm maintenance division supported a customer yesterday with their off-supply issue at a wind farm in Scotland, near Falkirk. An engineer attended site to assess the problem and found that the site had lost communications. The engineer checked the Scottish Power Network and didn’t find any problems. It was assumed that there was a loss of supply.

An investigation was then carried out and it was found that there was no supply to site or to the transformer to Scottish Power. The engineer contacted Scottish Power Energy Networks and discovered their switch had tripped on fault which was feeding the wind farm transformer.

A visual inspection was carried out on the transformer which didn’t indicate any stress or irregularities. The decision was made by Scottish Power to attempt a re-energization. The network tripped again immediately on fault and the decision was made to carry out an intrusive investigation.

The engineer then carried out a detailed investigation and it was discovered that Transformer 1 had a failure. An 11kV insulation resistance test was carried out which proved a fault on the HV winding. Swalek High Voltage Services are now in the process of sourcing and installing a new 800kVA transformer to replace the faulty transformer and ensure the wind farm continues to generate.

Swalek carry out wind farm high voltage design, build, operation & maintenance services throughout the UK and across Europe. Swalek deliver operation, maintenance and turnkey HV Design & Build (Civil & Electrical) balance of plant solutions for wind farm projects.

High Voltage Energisation of Solar Farms by HEIGHWAY Ltd

uploaded by Chris Dodds | Sales & Marketing Manager at Thorne & Derrick

HEIGHWAY Energy

for High Voltage Services

HEIGHWAY Ltd have successfully completed the Civils, Jointing, Connection & Commissioning package of works associated with the 33kV High Voltage Power Supply to a new build 5MW solar farm in the UK.

HEIGHWAY are a leading provider of HV Power Services to the renewable, rail, substation and energy sectors with an impressive track-record and future project pipeline following recent audit and Accreditation under the National Electricity Registration Scheme (NERS).

SOLAR FARM PROJECT NOTES

HEIGHWAY provided the following scope of works for the solar farm construction, commissioning and energisation:

• HV Cable Diversion Works
• HV Cable Installation to New Customer Substation
• HV Park Feeder & VT Connections
• Installation of 3 New Sets of CT’s
• Excavation Works to DNO Compound Including Installation of New Concrete Bases
• Installation of COP3 Metering Panels
• Full Commissioning of all Cabling, VT’s and CT’s & HV Switchgear

By George Heighway | Director at HEIGHWAY Ltd

The HV switchgear and transformers providing electrical power distribution at 33kV were connected using the Euromold brand of separable connector manufactured by Nexans – the Interface C Connectors were installed to the T Boot Station and the 33kV single core power cables were prepared, terminated and tested by our Jointers. Euromold bolted terminations are OEM approved and trusted by leading manufacturers of medium and high voltage electrical equipment including Lucy Electric, Siemens and ABB.

Reliance & Compliance

Our team of Jointers are Competent and Qualified in the installation of all types of cable joint and termination technology up to 33kV, including heat shrink and cold shrink, but the engineering preference of our HV Jointers for separable connector technology is the EPDM type manufactured by Nexans. Euromold kits are cost-competitive in the marketplace and readily available from stockists such as Thorne & Derrick, that said our focus as a business is not “lowest-cost” option. Our reputation rides on the reliability of the products we install and the expertise levels of our site teams that install them – also as a contractor we understand the criticality of accurate cable preparation using precision engineered cable tooling to achieve consistently high-quality results, for this reason our Jointing Team have standardised on tools manufactured by Alroc.

The Difference is Material

The Euromold separable connectors are manufactured from high quality EPDM which provides high mechanical strength which can be easily connected and disconnected from the equipment bushing for routine maintenance – competing silicone cable connectors have a tendency to attach and “stick” to the bushings and cannot be easily removed sometimes without damaging the actual connector. Euromold pioneered and innovated the separable connector – their products provide excellent resistance to compression, cutting, impact, tearing and abrasion over a wide temperature range.

HEIGHWAY are Hiring

HEIGHWAY Ltd are recruiting professional and experienced operatives:

– HV SAP/Project Engineer/s (33kV)
– HV Cable Jointer / Jointing Team (33kV)
– HV / LV Fitter/ Fitting Team (LV up to 33kV)

Configuration | the Interface C type connectors provide versatile and optional system design configurations. Here, our team of Jointers were deployed to “Piggy-back” the Euromolds into the medium voltage switchgear compartment. This dual-cable installation is enabled by the use of a connecting plug to mate the front-end connector to the back-end.

Service | Should you require technical support to enable the design or specification of 33kV power cable accessories or systems please do not hesitate to contact Thorne & Derrick, the Contracted & Approved UK Distributor for Nexans Power Cable Accessories.

Sealed & Supported | The 33kV single core power cables manufactured to BS7870 Standard were sealed at the transformer point of entry using heat shrink cable sealing glands to prevent water ingress and protect against cable damage. The cables are cleated to provide mechanical retention to the cable in position and electrical short circuit protection in the event of a fault situation.

11kV Services | Here HEIGHWAY Ltd completed the HV Isolation, Installation, Test, Termination & Commissioning of new 11kV transformer tails including preparatory de-vegetation works surrounding the site location which was heavily weeded and overgrown.
