A peak-shaving strategy that calculates unique thresholds for every Time-of-Use window. These thresholds account for both site load and TOU demand pricing, allowing the system to prioritize shaving where it provides the greatest economic benefit.
TOU Arbitrage
A specific form of Energy Arbitrage that operates within time-of-use (TOU) rate structures by charging the battery during off-peak or low-price periods and discharging during peak or high-price periods to reduce energy costs. TOU Arbitrage relies on predictable price windows and is most effective when the spread between off-peak and peak rates is significant. This strategy supports […]
Non-Export Limitation
A requirement that prevents a system from sending power back to the utility grid. Controls ensure net site output stays at or below zero kilowatts at all times. These requirements are common in jurisdictions with strict protection rules or limited grid hosting capacity.
Net Billing/Net Billing Tariff
A rate structure where exported energy is compensated at a different (often lower) rate than imported energy.
Load/Demand
The amount of electricity a customer uses at a given moment or averaged over time.
Interval Data
Detailed usage or production data measured at set time intervals (e.g., 5, 15, 30, or 60 minutes).
Interconnection Agreement
A formal agreement that defines how a solar or storage system must connect to and operate alongside the utility grid, including limits, protection requirements, and operating conditions.
Demand Ratchet
A utility mechanism where a customer’s billed demand is partially based on a prior peak (often from previous months), limiting short-term demand reduction savings.
Demand Interval
The time window over which demand charges are calculated (e.g., highest 15-minute average demand during a billing cycle).
