Doane Grant Thornton responds to Industrial Group information requests on NSIESO's budgeting practices, deferral account design, and filing requirements for the test year ending March 31, 2026
AI summary
- In response to IR-1, Doane Grant Thornton identified four areas where Nsieso practices diverge from Regulatory Approval Processes generally accepted utility practices (GUP): test year budget documentation, deferral account financial controls, absence of accounting policies, and lack of cost overrun thresholds (Exhibit N-12, pp. 3–52).
- Regarding IR-2, DGT confirmed it could not estimate potential variances for unsupported expense items but relied on industry benchmarking against comparable North American utility and non-profit organizations to conclude the proposed budget was "not unreasonable" (IR-2 Response).
- On IR-3, DGT clarified that "significance" is assessed using professional judgement considering magnitude, volatility, and decision-making impact, and recommended minimum Standardized Filing requirements including actual financial results, formal budget support, Indigenous and stakeholder engagement evidence, and deferral account justification (IR-3 Response).
- For IR-4, DGT stated both US GAAP and IFRS are acceptable for Nsieso but noted aligning with NSPI's existing US GAAP framework would improve comparability, transparency, and ease of transition (IR-4 Response).
- On IR-6 and IR-7, DGT recommended Prudence Reviews be triggered when cost categories exceed forecasts by a pre-determined threshold, proposed a 10% overrun tolerance consistent with the Alberta Electric System Operator's deferral account practice, and confirmed that deferral account establishment and ratepayer recovery require two separate Regulatory Approval Processes approvals (IR-6 and IR-7 Responses).
