Tariff stacking

Tariff stacking means combining more than one electricity pricing or reward arrangement, such as a time-of-use import rate, a solar export tariff, a smart EV charging offer, battery charging schedule or demand-flexibility reward. The term is about the interaction between those arrangements, not a separate tariff product, automatic savings method, export permission, SEG (Smart Export Guarantee) eligibility decision, DNO approval, export MPAN setup, smart-meter status, device compatibility verdict or proof that importing, storing and exporting electricity is allowed or profitable.
