Ontario Energy Market Highlights - 2026-04-08
📅 Date: 2026-04-08
🌦️ Weather Outlook
Ontario is set to experience a pleasant day with temperatures ranging from a cool 2.0°C to a mild 11.0°C. The forecast indicates predominantly sunny conditions across the key regions. This weather pattern is expected to moderately influence electricity demand, with a slight increase during peak hours due to heating requirements. However, the sunny conditions will favor renewable generation, particularly solar power.
⚡ Demand Forecast
Electricity demand will kick off the day around 14944 MW and is predicted to hit a peak of around 18321 MW at HE20. This intraday load shape aligns with the expected weather and daylight patterns, with a surge in demand expected during the evening hours. Looking ahead, next week's peaks are anticipated to hover around 18184 MW.
💰 Price Outlook
Day-Ahead (DAM) prices are projected to oscillate between $15/MWh and $94/MWh. Pre-Dispatch (PD) prices are likely to be more volatile, ranging from $20/MWh to a high of $134/MWh at HE6. This price behavior suggests a dynamic market with potential opportunities for strategic energy procurement and trading.
🔋 Generation Mix
The generation mix will be led by a steady nuclear output around 9003 MW. Hydro generation is anticipated to fluctuate between 4074–5359 MW, while gas generation may ramp up to 3645 MW during the evening. Wind generation will vary from 515–3952 MW, and solar generation is expected to peak near 325 MW around midday. Together, these resources will provide a balanced energy mix, ensuring system stability throughout the day.
🚧 Planned Outages
Today's planned outages are estimated as follows: Nuclear 3147 MW, Hydro 1276 MW, Gas 3799 MW, and Wind 3012 MW. Although these outages are significant, they are not expected to materially affect system flexibility or price volatility. This is due to the diversity of the generation mix and the availability of sufficient reserve capacity.
✅ Summary
Today's energy market outlook for Ontario is promising, with a balanced generation mix and moderate demand forecast. Despite significant planned outages, the system is expected to remain stable, supported by diverse generation resources. The sunny weather conditions will also favor renewable generation, particularly solar power. As the day progresses, market participants should monitor price fluctuations and adjust their strategies accordingly.
