Battery Carbon Shift Calculator

Simulate hourly grid charging and on-site load discharge with explicit efficiency, state-of-charge, and emissions accounting.

Scenario model—not a guarantee of emissions reductions. Results depend on the supplied average/marginal grid-intensity data and dispatch assumptions. Battery manufacturing, degradation, self-discharge, auxiliary loads, power prices, demand charges, grid feedback, and location-based accounting rules are excluded. Discharge is capped at on-site load, so exported energy is never credited or double-counted.

Hourly series

Positive action = grid energy used to charge. Negative action = battery energy delivered to on-site load. Rows must be unique, consecutive UTC hours. Auto mode ignores the action column. Up to 8,760 rows.
