Magna Park PSS

Project

Magna Park PSS (Primary Substation)

Location

Lutterworth

Contract

Electricity - EHV dual electricity circuits and 24MVA & PSS

Overview

HVSS were required to undertake the construction of a 24MVA PSS and associated EHV (Extra High Voltage) cabling works, approximately 6km including associated infrastructure for 17 commercial units. Preliminary works were undertaken to run HV cables to provide power to the first unit using a temporary solution that was subsequently embedded within the overall scheme. HVSS undertook the design, supply and commissioning of all SCADA monitoring and control for the EHV substation and the wider HV network’s embedded generation functionality

Challenge

A continuously evolving master plan and engineering difficulties required extensive reviews of all infrastructure and utility plans regularly. The project required complex directional drilling across the A5, resulting in substantial liaison with Highways England and the need to submit technical reports and assessments for approval. 6km of EHV cables were installed from the National Grid Pailton grid supply point (GSP) to the new primary substation at Magna Park. New electrical infrastructure, including interaction with a Tier 1 Main Contractor, was extended throughout the development. The skill set required to deliver this project was complex as the need to deliver on time whilst also breaking new ground with technology that the DNO hadn’t experienced before was a challenge. 

Solution

As the principal contractor, HVSS were responsible for undertaking the relevant notifications to the HSE due to the project size and duration. Flexibility around the ever-evolving site was critical noting the need to maintain a safe working environment under CDM regulations 2015. HVSS linked the end users G99 coupling relays, associated with the solar distributed generation, to an upstream constraint panel which is the first National Grid Constraint Panel that was interfaced and commissioned within the DNO network. HVSS’ experience with master planning as well as a clear understanding of the internal policies and processes within National Grid allowed us to adapt to the changes efficiently and effectively ensuring the client’s needs were met and project timings were not negatively impacted. Extensive design was undertaken with precise project management and the integral relationships with National Grid, Local Authorities and the client being crucial to a successful delivery. Effective project planning and risk management was applied to mitigate the extensive challenges and co-ordination around legals and civil works. Negotiation and the alignment of all parties were a key element in delivering to the clients’ build programme.
