Oregon Clean Energy Targets


In 2021 Oregon State Legislature passed the Clean Energy Targets bill. This bill requires  Portland General Electric, PacifiCorp and Electricity Service Suppliers  to reduce greenhouse gas emissions from the electricity they provide. The bill also created targets for these companies to reduce the greenhouse gas emissions from electricity sold in Oregon to:

  • 80 percent below baseline emissions levels by 2030;
  • 90 percent below baseline emissions levels by 2035; and
  • 100 percent below baseline emissions levels by 2040 

DEQ and the Public Utility Commission implement the program together. DEQ's main role includes:

  • Collecting greenhouse gas emissions data,
  • Calculating baseline emissions,
  • Calculating the reductions needed to meet the targets noted above,
  • and verifying projected emissions reductions. 

DEQ's evaluation is based on emissions data reports submitted by the electricity providers under OAR-340-215 to Oregon's Greenhouse Gas Reporting Program.

For more information, the Public Utilities Commission produced a summary of HB 2021 and published an implementation strategy.

DEQ Order determining baseline emissions

In May of 2022, DEQ issued an order determining the baseline emissions levels and emission reductions necessary for retail electricity providers to meet clean energy targets.

Baseline and Emissions Reduction Determinations

Electric Companies

Baseline emissions levels for Portland General Electric and PacifiCorp are calculated as the annual average emissions associated with electricity sold to retail consumers in Oregon for 2010, 2011 and 2012. These determinations are based on emission data reports submitted to DEQ adjusted as specified in the bill.

Electricity Service Supplier

The baseline determination for an Electricity Service Supplier is measured as an emissions intensity, on a per megawatt-hour bases. The initial baseline is equivalent to 0.428 metric tons of carbon dioxide equivalent per megawatt-hour (MTCO2e/MWh). For a supplier certified under ORS 757.649 on or after Sep. 25, 2021, the effective date of the bill, the baseline emissions level is adjusted downward to a level that reflects the progress made by other electricity service suppliers to meet the clean energy targets. 

Greenhouse Gas Emissions Projections

Portland General Electric and PacifiCorp are required to submit clean energy plans that include emissions projections showing that the planned actions will result in the required reductions for each of the milestones shown above.

DEQ's responsibility is to provide the emission factors to be used in those projections and review the provided projections to ensure that the calculations and emission factors used comply with DEQ's requirements for GHG accounting under our existing GHG Reporting Program. Read about how DEQ assigns emission factors to generating sources.

Detailed information on GHG emissions accounting and emission factors for use in Clean Energy Plan projections can be found below:

Verification of Projected Emissions Reductions

DEQ must verify greenhouse gas emissions projected in utility clean energy plans for power sold to retail electricity consumers. After verification is complete, DEQ issues an order with its findings and notify the utility and the PUC. These orders are made available to the public here.
