IESO Nova Scotia filed rebuttal evidence responding to Doane Grant Thornton and Synapse Energy Economics consultant reports on its 2025/2026 Revenue Requirement Application
AI summary
- Ieso Nova Scotia largely accepted Doane Grant Thornton (DGT) findings on its test year budget and organizational structure, but cautioned that recommendations — including a 10% over-expenditure threshold drawn from the Alberta Electric System Operator — should account for IESO Nova Scotia's nascent operational state and lack of historical data (DGT Evidence, M12412, p. 5; DGT IR-7 response, p. 12).
- IESO Nova Scotia agreed in principle to future Prudence Reviews of cost categories exceeding approved forecasts, requesting that the NSEB allow it to propose an appropriate threshold through future annual revenue requirement filings rather than adopting a fixed threshold immediately.
- On Integrated Resource Plan matters raised by Synapse Energy Economics (SEE), IESO Nova Scotia confirmed that key NS Power system planning staff have transferred to the organization, addressing SEE's concerns about technical expertise gaps (SEE Evidence, M12412, p. 9).
- IESO Nova Scotia advised that Dunsky Energy + Climate was selected through an RFP process (issued October 15, 2025) to assess and enhance the IRP development process, and that an Effective Load Carrying Capacity (ELCC) study is underway jointly with NS Power and consultant Energy + Environmental Economics (E3).
- IESO Nova Scotia noted it will determine its accounting framework in 2026 in consultation with its external auditor, taking into account DGT's jurisdictional review of ISO accounting standards (DGT IR-4 response, pp. 8–9).
