ORA’s central concern is that LT2 is being used, alongside the LLT RFP and roughly 1,800 kilometres of “priority” transmission, to advance ratepayer-backed repowered and new hydropower generation as quickly as possible, without a consolidated accounting of what it will cost ratepayers, in dollars and in emissions. Cost, emissions, public health impacts, fuel price exposure, and stranded asset risk are not external to affordability and reliability; they are a huge part of it. Environmental Defence made the same point in this engagement, cautioning that procurement frameworks “should not treat these externalities as irrelevant to affordability or reliability.” ORA agrees. The IESO’s own Hybrid Resource Portfolio Equivalency Assessment found that a portfolio of wind, solar and battery energy storage systems (BESS) can meet system needs “with 99.50 to 99.98 percent of load served” in every weather year modelled, and “can provide both baseload and peak power.” Wind, solar and BESS are cheaper, cleaner and faster to deploy than hydroelectricity, and far cleaner than gas.
