About Southern Scotland

Scotland generates more renewable electricity than it consumes, predominantly from wind, which means wholesale prices frequently drop to very low or negative levels during windy periods – creating significant opportunities for battery owners on smart tariffs. The Scottish Government’s Home Energy Scotland programme also provides additional support for energy efficiency and renewable installations.

According to MCS data, at least 3,998 certified home battery installations have been completed in the Southern Scotland region since September 2023 – part of a nationwide surge in domestic battery uptake.

Your savings with an 11.5kWh battery

The battery charges overnight at 9.5p and powers your home during the day, avoiding the 34.54p daytime rate. The saving is the difference between those rates, multiplied by how much energy the battery delivers each cycle.

The calculation (Octopus Go rates for Southern Scotland, April 2026)
11.5kWh × 90% round-trip efficiency = 10.35kWh usable per cycle
(34.54p daytime − 9.5p overnight) × 10.35kWh = 259p saved per day
259p × 365 days = £946/year
