Allow users to replace previously uploaded load shapes, impact profiles, and avoided costs

Currently load shapes are overwritten when re-uploaded.

The generated impact profiles should be replaced.

Background

Measure Developers may need to update previously submitted load shapes due to:

• Corrections to uploaded data

• Changes to eTRM permutations or assumptions

• Re-running simulations with updated modeling inputs

• QC findings identified after initial upload

Currently, CEDARS allows users to re-upload load shape files, which replaces the underlying load shape data. However, any previously generated Impact Profiles remain locked and cannot be recalculated. This can result in inconsistencies between the latest load shape data and the Impact Profiles and avoided cost combinations being used downstream.

In addition, users currently receive an error when attempting to regenerate Impact Profiles that have already been generated:

“Impact profiles have already been generated for the load shapes in this upload. Existing impact profiles cannot be recalculated.”

This limitation prevents Measure Developers from correcting or updating previously submitted data.

Proposed Enhancement

Allow users to replace previously uploaded load shapes and regenerate associated Impact Profiles and avoided cost combinations so that CEDARS reflects the latest approved data.

The enhancement should:

• Permit replacement of existing load shapes for a draft measure package.

• Allow existing Impact Profiles to be removed and regenerated from the updated load shapes.

• Provide transparency and safeguards to prevent unintended overwrites.
