For builders of energy software

Make every energy decision price-aware.

Turn energy behavior into dollars, cents, and CO2e.

WattShift turns utility tariffs, DR programs, VPP markets, carbon intensity, and export compensation into one API for operating decisions and customer-facing value proof.

Solutions

That turn price data into action.

Start where your workflow needs help: runtime signals for operation, impact modeling for value proof, and Utility Rate Database underneath both.

Unified optimization signal

Price Signals

Aggregate tariffs, wholesale prices, export rates, demand response, and carbon intensity into one weighted price indicator for product behavior.

Key Use Cases
Solar + Battery: Optimize charge and discharge times for maximum savings.
Smart Thermostats: Identify when electricity is cheap and clean versus expensive and dirty.
EV Charging: Ensure EVs charge at optimal times for cost and grid benefits.
Value proof and modeling

Impact Calculations

Show customers the value of your offering in dollars, cents, carbon, and bill outcomes across device configurations and tariff scenarios.

Key Use Cases
Solar + Battery ROI: Demonstrate value even under complex export tariffs like NEM 3.0 and VDER.
Device Savings: Estimate dollars and pounds saved from your device's smart operation.
Tariff Optimization: Discover savings opportunities from tariff switching.
EV Cost Analysis: Understand the marginal cost of every charging session.
Powered by WattShift's Utility Rate Database

Tariff truth underneath every signal and calculation.

Product-ready tariff and export rules give Price Signals and Impact Calculations the underlying economic truth they run on, so teams can build on one consistent engine instead of stitching together utility logic themselves.
