Enabling broader decarbonization through Energy Systems Integration

The document argues that while Canada has made progress in decarbonizing power supply, achieving net-zero requires Energy Systems Integration (ESI)—the coordination of energy systems across multiple pathways and scales. It examines five key ESI technologies (electric vehicles, heat pumps, demand response, distributed generation, and hydrogen) and finds that Canadian policy is currently too siloed, relying on voluntary 'soft' incentives rather than systemic market reforms or mandatory legislation. The author highlights significant gaps in information, governance, and implementation, suggesting that a holistic, pan-system approach to modelling and planning is essential to avoid sub-optimal infrastructure lock-in.

• Energy Systems Integration (ESI) is defined as the coordination of energy systems across multiple pathways and geographical scales to provide reliable, cost-effective energy services with minimal environmental impact. It encompasses electrification but is broader, including technologies like hydrogen for seasonal storage and renewable natural gas for hard-to-electrify end uses.
• The maturity of ESI technologies varies significantly: electric vehicles and utility-scale solar PV are considered "on track" to contribute to decarbonization, while demand response and heat pumps are "lagging but viable". Hydrogen vehicles and industrial applications are currently "not viable at current pace" due to a lack of large-scale energy systems.
• Canadian ESI policies are predominantly "soft" voluntary incentives (such as rebates) rather than mandatory legislation or cost-reflective tariffs. The author notes that this approach mirrors past failures, such as the inability to meet Kyoto Protocol commitments due to insufficient adoption of voluntary measures.
• There is a significant lack of coordination between different levels of government and utilities regarding EV adoption. For example, while the federal government has targets, Hydro-Québec's supply plan for 0.9 million EVs does not align with the provincial target of 1.5 million by 2030, and SaskPower does not refer to an EV adoption target in its long-term forecasts.
• Hydrogen infrastructure in Canada is in early stages and lacks essential injection and quality standards for blending into natural gas grids, as well as a framework for inter-provincial coordination. National targets include 50% hydrogen mixing in existing natural gas networks by 2050.
• Current energy modelling is siloed, with operational transport and building models typically disconnected from power system dispatch models. This prevents a holistic understanding of electrification pathways and the interaction between different energy vectors.
• To overcome ESI challenges, the author recommends replacing siloed power planning with regional integration, replacing voluntary building sector incentives with mandatory legislation, and implementing market reforms that remunerate flexibility services rather than providing one-off subsidies.
