As the UK accelerates its energy transition and reduces import dependence, more and more renewable energy sources are being introduced into the local power grid – solar energy being a crucial component. However, because solar power generation is affected by weather and diurnal variations, it cannot independently produce a continuous, stable, and dispatchable power supply, posing a challenge to meeting power demand.
Project Background
To address this issue, a leading UK solar developer, leveraging its comprehensive experience from project design and construction to post-construction operation and maintenance, has focused on developing "Solar Energy Storage Systems (BESS)".
By combining energy storage systems with solar power plants, the previously intermittent solar assets are upgraded into more stable and resilient energy infrastructure. Simultaneously, this "local generation, local consumption" model better supports the operation of the regional power grid.
One benchmark project in eastern England alone exemplifies the value of this model: Annual power generation: 20,000 MWh
Electricity demand met: 5,000 homes
However, as more and more hybrid energy sites are built in remote, unattended areas, the company faces new challenges: how to manage these complex sites stably and efficiently over the next 10 years.
Ensuring the continuous operation of critical energy facilities requires more than just hardware; a reliable and secure network system is also needed to prevent communication failures and security vulnerabilities from affecting plant operations and even threatening regional energy supply security.
To this end, the company partnered with Moxa to build a standardized and secure communication backbone network, ensuring long-term stable interconnection of equipment and continuously improving operational efficiency.
Project Requirements
Scalable Product Portfolio:
Standardized and replicable, enabling rapid expansion across regions for multiple hybrid energy sites.
Seamless Subsystem Integration:
Seamless data exchange between PV inverters, BESS cabinets, and CCTV systems is required to ensure real-time grid response.
Easy Remote Management:
A highly reliable communication backbone network allows for real-time visibility of the status of unattended distributed sites.
Industrial Network Security:
A network compliant with the "Security by Design" principle and IEC 62443 standards effectively reduces regional energy security risks.
Sustainable Operation:
Capable of continuous and stable operation for over ten years in harsh outdoor environments.
