Correction to the 2023 IEPR Additional Achievable Fuel Substitution (AAFS) Hourly Results - DAWG Meeting

Please join us for an upcoming Demand Analysis Working Group (DAWG) meeting on Wednesday June 12, from 9:00-10:00 am, where staff will provide an overview of the correction of an error discovered in the 2023 IEPR additional achievable fuel substitution scenario hourly results and next steps. The meeting will be held via webinar-only. 

The key topics of discussion for this DAWG meeting will be:

• The discovery of the error in one of the model input files for the AAFS (Additional Achievable Fuel Substitution) scenarios in the 2023 IEPR demand forecast which impacts the hourly electricity results. For the portion of AAFS that was modeled using the Fuel Substitution Scenario Analysis Tool (FSSAT), a cooling load shape was incorrectly applied to a portion of HVAC heating load.
• The electricity impacts from correcting the error. Correcting the error reduces summer load and increases winter load.
• Overview and status of stakeholder outreach and next steps.

An agenda and materials will be posted in advance of the webinar to the DAWG webpage. Future meeting announcements will be sent only to the Demand Analysis Working Group list. Use the link above to subscribe.
