Scottish Water has deployed 372 solar panels at the Lawhead Treated Water Pumping Station in Penicuik. The system generates approximately 0.15GWh of electricity annually, covering 27% of the facility's total energy needs and reducing carbon dioxide emissions by 28 tonnes per year. The project uses a mix of tank and ground mounted panels to lower operational costs and protect the utility from volatile electricity prices. Excess power is exported back to the national grid, supporting Scottish Water's goal of reaching net zero emissions by 2040.

27% of demand is a decent start for a pumping station, but I wonder about the peak load. Pumping is energy intensive. Does the site have any battery storage to handle the gaps, or is it just straight grid fallback?

Usually these utility projects focus on the easy wins first. The real policy question is whether these distributed assets get better tariff treatment for exporting surplus power or if they are just offsetting OpEx.

Using the tank surfaces for mounting is a smart move. It saves land and reduces installation costs. I would be curious to see the maintenance plan for those tank mounts over the next ten years.

Scottish Water is pushing a lot of these small scale solar sites. 28 tonnes of CO2 saved is small in the grand scheme, but it adds up if they do this across the whole network.
