The CPUC recently released the 2021 version of the electric and gas Avoided Cost Calculators (ACC). These updates will directly impact the valuation and cost-effectiveness of demand side programs in California.
Recurve has incorporated the new 2021 ACC values into the FLEXvalue toolkit, an open source suite of cost effectiveness tools and databases that allow users to utilize custom or measured load shape impacts among other enhanced functionality. For more information see flexvalue.recurve.com and the GitHub library.
The FLEXvalue calculator has been updated to enable users to input either 2020 or 2021 in their cost-effectiveness calculations to designate which version of avoided cost data is to be used.
The ACC models are published in macro-driven Excel workbooks. These workbooks are useful for a quick look or to copy a small slice of data, but with hundreds of utility/year/climate zone combinations, a database structure is essential for many use cases. For users who would benefit from having a clean database version of all avoided cost data, Recurve has scraped all avoided cost data and made the full SQLite databases publicly available for download (here). Note that the ACC is subject to change, so please check back in the coming weeks for updates.
For those interested in producing comparisons between the 2020 and 2021 avoided cost data and the impact on TRC, Recurve has also assembled a Colab Notebook, which enables this type of exploration using FLEXvalue.
Recurve has also copied the ACC models themselves (Download .xlsb files here).
