Case Study

Converting Grid Access into Scalable Battery Storage Infrastructure

The Project

Reaching the UK’s legally binding Net Zero 2050 target will require a substantial expansion of renewable generation alongside widespread electrification of transport and heating. As electricity demand increases and renewable output becomes more variable, pressure on local distribution networks continues to intensify.

For organisations with access to grid connections and suitable land, this shift presents both constraints and opportunities. Ensuring you have a partner who can navigate the constraints and take advantage of the opportunities is essential.

Multiple UK Sites

From Net Zero Commitment to Infrastructure Opportunity

Battery Energy Storage Systems (BESS) provide a decentralised solution designed to address the mismatch between renewable generation and real-time consumption, whilst also providing voltage regulation through the use of inverters to manage active and reactive power, assisting the DNO in managing voltage fluctuations. Each installation, with a footprint comparable to two standard parking bays, connects directly to the local distribution network, capturing surplus renewable energy during periods of oversupply and discharging it back into the grid at peak demand, ensuring the DNO networks can continue to meet the ever-changing demands placed upon them.

By smoothing supply–demand imbalances, battery storage reduces carbon intensity, strengthens local grid stability and supports the resilience of the UK’s evolving energy system. Our client sought to develop newly acquired locations with available grid access into structured, revenue-generating energy infrastructure assets.

Clarke Connect was appointed to provide end-to-end integration, compliance management and programme delivery.

Project Challenges and Solutions

Managing Grid, Regulatory and Commercial Risk

Deploying battery storage within the UK distribution network is more than a construction challenge. It requires disciplined management of three dominant risks:

Grid connection certainty
Commercial revenue certainty
Planning and regulatory compliance

Engineering and installation can be structured and controlled. Grid approvals, DNO coordination and commercial structuring demand a deeper understanding of network constraints and governance.

To support our client, our knowledge and experience in the following areas were essential.

Grid applications and approvals
Detailed engineering design
Planning and regulatory compliance
Construction and installation
Commissioning and grid compliance testing

Delivery also needed to align with shareholder expectations and accelerated timelines, while addressing inherent safety considerations associated with lithium-ion battery transport and installation. The challenge was not simply technical deployment, it was structuring certainty within a constrained, third-party-dependent environment.

Structuring Certainty At Scale

Rather than approaching each site as a standalone installation, we structured the programme as a scalable energy infrastructure platform. We placed early focus on securing clarity around grid connection and integrating DNO coordination into our programme governance.

By investing in structured pre-planning and early regulatory engagement, we mitigated uncertainty later in the process, strengthening both technical assurance and commercial viability.

A proactive engagement model was established with DNO planners, highways authorities and technical partners, shifting delivery from reactive deployment to controlled progression.

To date, the programme has achieved:

84 battery sites constructed
50 sites live and commissioned
Ongoing phased rollout across additional locations

Wayne Brierley, Business Development Director at Clarke commented on the project:

By combining large-scale delivery experience with grid integration expertise, we enabled high-volume, short-duration site works to progress despite third-party challenges and network constraints.

A fundamental advantage for clients working with us is our single-source accountability across design, compliance, construction and commissioning. As an appointed Principal Designer (PD) and Principal Contractor (PC), we ensure full compliance with CDM 2015 regulations across project lifecycles.

Unlocking Latent Grid Value And Strengthening Network Stability

Battery storage has progressed from an environmental initiative to an infrastructure stabiliser and a structured commercial asset.

Through disciplined integration of grid access, engineering design and commercial governance, the programme has transformed constrained network connections into resilient, revenue-generating infrastructure.

In addition to its commercial value, each battery installation also contributes to wider grid stability, responding in fractions of a second to fluctuations in supply and demand and supporting the resilience of the local electricity network. In doing so, we’ve provided not only grid stability benefits, but a structured revenue stream aligned to market flexibility mechanisms.

Each installation supports:

Lower local carbon intensity
Improved network stability
Reduced reliance on imported fossil generation
A scalable foundation for future energy system growth

For the client, this programme demonstrates that disused land and grid access can be converted into bankable energy assets, delivered with managed technical and commercial risk.

Operational Confidence Secured

By investing in decentralised battery storage aligned to national Net Zero objectives, our client has positioned itself at the forefront of grid-responsive infrastructure development.

The programme establishes a repeatable, scalable model for converting network constraints into commercial opportunity, strengthening energy resilience, enhancing system flexibility and supporting the UK’s transition to a lower-carbon electricity network.

Clarke Connect has enabled this transformation by aligning grid expertise, regulatory navigation and infrastructure delivery within a single accountable framework, ensuring battery storage is delivered not as a standalone installation, but as a future-ready energy asset platform.
