PRACTICAL ENGINEERING
WHAT WE DO
RHD Scotland combines hands-on renewable energy installation with specialist electrical, automation and monitoring expertise.
We work across the full energy chain: generating electricity, integrating storage, controlling equipment and understanding how energy is used on site.

01 / SOLAR PV & BATTERY STORAGE
RHD Scotland provides a complete solar PV installation service, from initial planning and liaison with the Distribution Network Operator (DNO), through installation and commissioning, to ongoing maintenance.
We also install battery storage systems and can integrate generation and storage with the wider electrical infrastructure and energy management requirements of a site.

02 / MICRO HYDROELECTRIC
RHD Scotland has designed and installed bespoke control systems for micro hydroelectric schemes rated below 100 kW at more than 20 sites.
Our work brings together control hardware, PLC programming, instrumentation and monitoring to suit the operating requirements of each individual scheme.

03 / ENERGY OPTIMISATION
Dairy operations can have substantial demand for hot water, often at different times from periods of renewable generation. RHD Scotland has been involved in energy optimisation and hot-water thermal storage systems for dairies with high process demand.
By coordinating generation, heating and stored hot water, bespoke control systems can help make useful heat available when the process needs it. The approach is sometimes described as a “hot water battery”.
CONTROL & MONITORING
Generation and storage are only part of the picture. RHD develops bespoke controls and monitoring to connect equipment with real operating requirements.

Beckhoff PLC-based control, distributed EtherCAT I/O and communications designed around the site.

Power, temperatures and operational trends brought together to inform control decisions.
CONTROL & MONITORING IN PRACTICE
An operator interface brings generation, site conditions and energy flows together in one view.
