What it can do
| Tool | What it says it does |
|---|---|
calculate_emissions | Calculate Scope 2 CO2e for a facility from its ZIP and kWh, using both GHG Protocol methods: location-based (eGRID subregion rate) and market-based (Green-e residual mix applied to kWh not covered by RECs, PPAs or green tariffs). Returns kg CO2e for each method with the factors used. |
calculate_fuel_emissions | Calculate Scope 1 stationary-combustion emissions (CO2, CH4, N2O and CO2e) for fuels burned on site, using the GHG Emission Factors Hub 2026 (Cornerstone, successor to EPA's Hub; IPCC AR6 GWPs) by default, or EPA's 2025 edition (AR5) with edition=2025. Pass one or more items with fuel, quantity… |
cleanest_hours | Find the cleanest (lowest grid carbon) contiguous window of N hours in the day to run a flexible load (batch jobs, EV charging, pumping, HVAC pre-cooling) at a US ZIP code or balancing authority. Based on the hour-of-day pattern of the last 7 days (168 hours) of EIA-930 data, in local time… |
compare_sites | Compare and rank 2-25 candidate US sites (ZIP codes) for a facility, data center or EV/flexible load on grid carbon and electricity cost in one call. Per site: eGRID CO2e kg/kWh (location-based), Green-e residual mix (market-based), carbon-free %, $/kWh for the sector (the state's latest full-year… |
electricity_rate | Get the latest monthly average retail electricity rate ($/kWh and cents/kWh) for any US ZIP code, broken out by sector (residential, commercial, industrial, etc.). Data is state-level from EIA Form 861 - a ballpark, not utility- or ZIP-specific tariffs (use utility_tariff for those). |
hourly_intensity | Get hourly grid carbon intensity (kg CO2e per kWh) for any US ZIP code, derived from EIA-930 hourly fuel-mix data. Data lags up to about a day (not real-time). Returns time series with per-hour fuel mix, total generation, and carbon intensity. For timing and analysis (demand response, load… |
lookup_batch | Look up emission factors for up to 100 ZIP codes in one call (split longer lists). Returns one compact row per ZIP - subregion, CO2e kg/kWh (location-based), residual mix (market-based), carbon-free %, utility - unless full is true, which returns every field (about 2 KB per ZIP). |
lookup_by_coordinates | Look up emission factors by latitude/longitude. Uses US Census Geocoder to resolve to ZIP first, then returns the same data as lookup_emission_factor. Useful when you have a facility address or lat/lon but no ZIP. |
lookup_emission_factor | Look up EPA eGRID electricity emission factors for a US ZIP code. Returns CO2e (kg/kWh and lb/MWh), CO2, CH4, N2O, NOx, SO2, non-baseload rate, carbon-free %, generation mix (coal/gas/nuclear/hydro/wind/solar etc.), eGRID subregion code, the data year, and the Green-e residual mix rate (the… |
plant_emissions | Get emissions from EPA Clean Air Markets Division (CAMD) for a specific US power plant or a state: fossil units over 25 MW reporting to the Acid Rain Program and CSAPR. Per facility returns total CO2 (short tons), gross generation (MWh), heat input (mmBtu), NOx and SO2 (lb), primary fuel type… |
utility_tariff | Get the actual utility-specific electricity rate (not state average) for a US ZIP code or named utility. Returns the current default tariff with effective rate ($/kWh), fixed monthly charge, tier count, TOU indicator, and effective date. Data source: OpenEI URDB (NREL-hosted). With a ZIP, matches… |
In its maker's words
Keyless US grid carbon + power cost by ZIP: eGRID Scope 2, Scope 1 fuels, site ranking, clean hours
