Maintain | Sustaining Renewable Generation and Storage at Castleview Low Carbon Vehicle Hub

Project Context

The Castleview Low Carbon Vehicle Hub was delivered as part of Scotland’s A9 Electrification Scheme, integrating 276kWp of solar PV, a 446kWh battery energy storage system, and EV charging infrastructure within a live park-and-ride environment. 

Following the handover in November 2020, Stirling Council required structured maintenance support to protect system performance, ensure compliance, and safeguard the long-term value of its renewable investment. 

As a publicly accessible transport asset supporting national decarbonisation targets, maintaining reliability and safety is critical to continued success. 

The Challenge

Solar PV and battery energy storage systems require specialist oversight to maintain output and ensure operational safety. Over time, inverter performance, electrical connections and storage systems can degrade without structured inspection and monitoring. 

For Stirling Council, the priority was to sustain renewable generation, protect capital investment secured through Low Carbon Travel and Transport funding, and ensure EV charging infrastructure remained reliable for users. 

Our Maintenance Approach

OCS provides planned, reactive and specialist maintenance support across the solar PV and battery energy storage systems at Castleview. 

Planned preventative maintenance inspections are carried out to review panel condition, inverter performance, electrical integrity and storage operation. Compliance checks are embedded within the maintenance regime to ensure continued adherence to electrical safety standards in a live public environment. 

Performance is monitored through a Trend energy monitoring system, the solar PV online portal, and the EV charger manufacturer platforms. This layered visibility enables early identification of anomalies and allows engineers to intervene before performance is materially affected. 

At handover, OCS supported Stirling Council through a structured soft-landings period, providing system training to estates and management teams to ensure confidence in the ongoing operation. 

What This Enables

This integrated maintenance strategy supports sustained renewable generation, stable battery operation, and reliable EV charging provision. 

Early fault detection reduces the risk of energy loss, extends asset life, and protects lifecycle value. It also provides assurance that the hub continues to operate safely and efficiently in a public setting. 

Outcome 

The Castleview Low Carbon Vehicle Hub continues to generate approximately 250,000 kWh of renewable electricity annually, supporting local carbon-reduction and transport objectives. 

Through structured maintenance and specialist oversight, OCS supports Stirling Council in protecting performance, maintaining compliance and sustaining long-term energy resilience across its renewable infrastructure.
