Oregon Electricity Emission Factor 2023

EPA eGRID2023 Rev2 · NWPP subregion

Power plants in Oregon emitted 365.0 lb CO2e per MWh generated in 2023 (0.1655 kg/kWh), 53% cleaner than the US average, according to EPA's eGRID2023 state rate. Their generation was 62% carbon-free and 62% renewable. For GHG Protocol Scope 2 location-based reporting, use the eGRID subregion factor of each facility's ZIP (below), not the state rate: power flows across state lines within a subregion.

How to Use Oregon's Emission Factor for Scope 2 Reporting

For GHG Protocol Scope 2 location-based emissions reporting, multiply each facility's electricity consumption by the emission factor for its ZIP code's eGRID subregion. All Oregon ZIP codes use the NWPP factor: 635.267 lb CO2e/MWh.

Frequently Asked Questions

What is Oregon's electricity emission factor?

For Scope 2 reporting, it depends on the ZIP: all are in NWPP, 635.267 lb CO2e/MWh. EPA's state rate for plants in Oregon is 365.0 lb CO2e/MWh, 53% cleaner than the US average.

How do I calculate Scope 2 emissions for a Oregon facility?

Multiply the facility's annual kWh by the kg/kWh factor of its ZIP code's eGRID subregion (0.2882 for NWPP) to get kg CO2e, and divide by 1,000 for metric tonnes. The emission factors API returns the factor for any ZIP.

How clean is Oregon's electricity grid?

Power plants in Oregon generated 62% carbon-free and 62% renewable electricity in 2023. At 365 lb CO2e/MWh, the state rate is 53% cleaner than the US average of 770.9 lb/MWh.
