The Industrial Group issued seven information requests to NSIESO's independent reviewer Doane Grant Thornton probing evidentiary gaps, filing standards, and deferral account design in the IESO's FY2026 revenue requirement application

M12412 · Nova Scotia Independent Energy System Operator (IESO Nova Scotia) - Proposed expenditure and revenue requirements for test year ending March 31, 2026

AI summary

The Industrial Group (represented by Stewart McKelvey) directed IR-1 through IR-7 to Doane Grant Thornton (Exhibit N-10), with responses due December 9, 2025, in the context of NSIESO's application under the More Access To Energy Act for approval of its test-year expenditure and revenue requirement ending March 31, 2026.
IR-1 and IR-2 press DGT to cross-reference all noted departures from Generally Understood Practices (GUP) and to quantify potential variance for expenses the application supported only through generic market information and informal discussions, rather than formal quotes (Exhibit N-10, p. 31, lines 16–30).
IR-3 challenges DGT to define "significant" in its recommendation for minimum Standardized Filing requirements and to compare those requirements against other jurisdictions with an Independent Electricity System Operator, including identification of jurisdiction-specific elements unsuitable for Nova Scotia (p. 31, lines 25–30).
IR-4 asks whether DGT recommends US GAAP or IFRS for NSIESO accounting policies and whether alignment with Nova Scotia Power's chosen framework is relevant (p. 48).
IR-5 through IR-7 interrogate the design of NSIESO's proposed Net OM&A Deferral and Variance Account (DVA): specifically, whether bifurcating costs into sub-accounts is the most efficient approach, whether the DVA is time-limited or ongoing, whether the "net" framing should be removed given DGT's own Prudence Reviews recommendation, and whether thresholds or limits on DVA overruns should be established — including whether deferral account creation and ratepayer recovery require two separate regulatory approvals (pp. 49–52).
