Interstate Power and Light Company Responds to Iowa Utilities Commission Requests

The Iowa Public Utilities Commission's request for additional information regarding Interstate Power and Light Company's (IPL) Electric Energy Efficiency Cost Recovery (EECR) and Demand Response Cost Recovery (DRCR) filings has been met with a detailed response from IPL. In its submission, IPL addresses concerns about discrepancies in energy efficiency spending and program allocation, providing revised workpapers to clarify the matter. The company's response acknowledges errors in reporting and assigns the affected dollars to the electric energy efficiency plan.

Key Takeaways:

• IPL explains the discrepancy in energy efficiency spending for gas in its EECR and DRCR filings, attributing it to an error in timesheet reporting.
• The error resulted in $705.94 being listed under the gas energy efficiency plan instead of the electric energy efficiency plan.
• IPL does not have a budget for gas demand response in Docket No. EEP-2022-0150, and the affected dollars were not included in the EECR and DRCR filings.
• The company submits revised workpapers (Attachments A and B) showing the corrected assignment of dollars to the electric "Non-residential - SmartHours" program as an admin expense.
• This adjustment does not impact the proposed rate factors for electric EECR or DRCR.
