Who earns what — and where?
British market roles, clearly separated.
Balancing responsible / trader
Reads here when charging is worthwhile: at negative prices, you are paid to charge.
Asset operator
More negative intervals = more economically usable cycles for the battery.
Investor
A rising share of negative intervals widens the business case — without extrapolating from a single month.
System operator (NESO) / exchanges
Negative prices reflect overproduction; the market clears the surplus, the system operator handles grid balance. No trading profit.
