At the core of all our products.

Accurate Tariff Rates

Flexible Usage Data

Powerful Rate Engine


Comprehensive, accurate utility rate data

U.S & International Coverage

We capture all residential, commercial, industrial and specialty tariff rate plans for all of North America, Australia and select other markets. This includes complete regulated market data and select data in deregulated markets.

Accurate & Detailed

We capture all the details. Every rate component, tariff eligibility rule and rate option. We support every rate structure we've found, from the simplest flat consumption rates, through tiered and time of use pricing, to system and dynamic peaks, complex ratchets and sophisticated billing rules. We have utility service areas and baseline regions, holiday schedules and more.

Always Up-to-date

We track all rate changes and typically QA and publish them in less than 1 business day. That's over 15,000 tariff book updates every month, and growing. We also maintain current electricity market and hourly retail pricing.


Flexible usage data tools

Our products work with whatever usage data you have. Green button data, AMI readings, annual usage, a single utility bill: we generate costs and savings in all cases.

A large database of hourly usage, cost and rate data spanning the entire country. Ideal for any situation where you don't have actual usage data or would like to compare with similar homes and businesses.


World's most powerful rate engine

Our calculation engine takes electricity usage and returns costs and savings. It's the product of six years of software development, and is field proven through tens of millions of calculations. The only rate engine built from the ground up with the flexibility needed for New Energy.

Blazingly fast. Real time. Internet scale.

Speed and scalability are embedded in the core of all of our calculators, including ones that compute historical and month-to-date bills, compare tariff rate plans, forecast solar and efficiency savings, and signal real-time load and battery optimization. It's flexible, returning results with the cost and time interval granularity you require. All available via our APIs and web applications.
