Makes sense, and then you can split consumption (or production - arbitraging with a battery) into time-of-use buckets (a kWh of electricity already has different costs if you're buying during peak hours vs off-peak vs super-off-peak), or spot prices vs reserve prices. In commodities terms, I feel like it would be similar to futures and spot-price. Those who can buy their energy in bulk and store it efficiently, or only consume when the price is lower than X, will pay a lower rate than those who cannot store energy, or who pay to have someone else store it (again, arbitrage)
