Battery Arbitrage
COMMERCIAL SCALE — SYSTEMS FROM 100kWh

Commercial Battery
Arbitrage Scotland
C&I Systems

Commercial and industrial battery storage from 50kWh to 10MWh. Multiple revenue streams: wholesale arbitrage, capacity market, Triad avoidance, and DNO flexibility services.

Commercial Revenue Streams

Wholesale Arbitrage

Buy electricity at low wholesale prices (often negative during high wind) and sell back at peak. Same principle as home arbitrage but at commercial scale.

Annual Revenue
£8,000–£120,000/year
Min System Size
100kWh–10MWh

Capacity Market

4-year contracts with National Energy System Operator (NESO). Guaranteed revenue for committing capacity availability during system stress events.

Annual Revenue
£12,000–£180,000/year
Min System Size
500kWh+

Triad Avoidance

Reduce demand during the 3 highest half-hours of winter. Can save £20,000–£400,000/year for half-hourly metered sites.

Annual Revenue
£20,000–£400,000/year
Min System Size
200kWh+

DNO Flexibility

Local flexibility services from your Distribution Network Operator. Revenue for reducing demand at constrained times on the local network.

Annual Revenue
£5,000–£80,000/year
Min System Size
100kWh+

Why Commercial Battery Storage Makes Sense in Scotland

Scotland's electricity market is uniquely suited to commercial battery arbitrage for four reasons:

  • High renewable penetration: Scotland regularly generates 100%+ of its electricity demand from renewables, creating frequent negative pricing events.
  • Grid constraints: Limited interconnection capacity means local flexibility is highly valued by DNOs.
  • Triad charges: Scottish sites on half-hourly meters face significant Triad charges — battery storage can eliminate these entirely.
  • Capacity market access: Scottish BESS projects are eligible for capacity market contracts with guaranteed revenue for 4 years.

For businesses with existing half-hourly meters and high winter demand, commercial battery storage can deliver paybacks as short as 3 years when combining multiple revenue streams.
