Envigour Policy Consulting raises four unresolved analytical questions before closure of NSPI's Integrated Resource Planning scenario process
AI summary
- Consultant Bruce Cameron of Envigour Policy Consulting, retained by Quest and Marine Renewables Canada, submitted a July 17, 2020 letter in Integrated Resource Plan IRP matter M08929 urging further analysis before the IRP Roadmap is finalized.
- Cameron flagged that the model treats Distributed Energy Resources (DERs) solely as demand reductions without assigning system costs, and questioned whether this approach undervalues combined solar PV and storage, conflicts with Enhanced Net-metering obligations, or adequately addresses Community Solar PV Gardens sought by several NS municipalities.
- The letter requested disclosure of the cost gap between technologies selected by the model and those not chosen — specifically offshore wind, tidal, and hydrogen — and asked how unique attributes such as tidal predictability were (or were not) valued in the modelling.
- Cameron recommended fuller analysis of natural gas combined-cycle gas turbine (CCGT) solutions appearing in multiple scenario runs, including reliability risks from single-pipeline dependence and the absence of local gas storage, and pathways to a net-zero electricity system by 2050 if CCGT investment proceeds.
- The letter also asked whether the IRP process can distinguish which scenarios would preferentially utilize Nova Scotia-sourced goods and services on both a CAPEX and OPEX basis, noting differing GDP impacts across scenarios.
