The most common trigger for a commercial HV LV electrical upgrade is a planned renewable energy investment, but businesses often discover the infrastructure constraint only after they have committed to a solar or storage project. EvoEnergy identifies electrical infrastructure requirements at the feasibility stage, before any commitment is made, so clients understand the full investment picture from the outset.
The following scenarios typically indicate that an HV/LV upgrade is required:
Solar PV over 100 kWp: Large systems require G99 DNO approval and may need new metering, protection relays, and LV distribution upgrades to handle generation export.
Battery storage integration: Commercial BESS systems require high-power connections capable of rapid charge and discharge cycles; existing distribution boards are often undersized.
Site expansion or load growth: New production lines, refrigeration capacity, or process plant can exhaust existing electrical headroom, requiring a capacity upgrade before additional loads can be connected.
Ageing infrastructure: Transformers, switchgear, and distribution boards installed before 2000 may be at or approaching end of life, with maintenance costs rising and replacement parts increasingly difficult to source.
Grid export ambitions: To benefit from SEG export tariffs or grid services revenue from battery storage, your site connection must have adequate export capacity, which many existing incomers do not.
