   Estimated buildout target through 2030

   Grid connection by end of 2030. OPG’s planning goal is completion of the first SMR by the end of this decade and grid connection by the end of 2030. Only Unit 1 is included; three future reactors require further approvals.

   Construction is verified; the completion date remains an estimate. The timeline marker represents the published target year/month, not a confirmed opening day.

   OPG publishes a C$7.7 billion release-quality budget for the first SMR and shared site infrastructure: C$6.1 billion Unit 1 plus C$1.6 billion common systems/services. The budget includes interest, escalation and contingency. Included output is the first 300 MWe reactor under physical construction; the three additional proposed units and their combined C$20.9 billion fleet budget are excluded.

Costs use the published scope and currency; no benchmark estimates or currency conversions. MW is power capacity, not annual electricity production. Expected annual energy, where given, is a forecast. The map point is a reported plant/project location and may be approximate. Matching inventory views and excluded expansion proposals are not additive capacity.

   OPG Starts Building Canada's First Grid-Scale SMR at Darlington→Darlington New Nuclear Project — Unit 1 — under construction

   المقدمة

   قبل

   Ontario Power Generation began construction of the first of four 300 MW BWRX-300 small modular reactors at Darlington on 8 May 2025, a month after the CNSC licence to construct; the first unit is due in service by the end of 2030 at a cost of C$7.7 billion.

   • On 8 May 2025 Ontario gave OPG the green light to build the first of four BWRX-300 units at the Darlington New Nuclear Project, the first new nuclear build in the province in more than three decades and the first grid-scale SMR under construction in any G7 country, a month after the Canadian Nuclear Safety Commission issued the licence to construct
   • The first 300 MW unit is due in service by the end of 2030 (OPG had earlier anticipated the end of 2029), with the full fleet of four units producing 1,200 MW and the other three planned for the mid-2030s
   • Ontario's energy minister put the first unit at C$7.7 billion, C$6.1 billion for the reactor and C$1.6 billion for systems and services common to all four units; the four-unit plant is estimated at C$20.9 billion
   • By spring 2026 the reactor's steel-and-concrete basemat module had been lifted into the excavated, 35-metre-deep reactor shaft, shortly before 8 May 2026, a year to the day after the final investment decision
   • OPG submitted its licence to operate application for the first unit in March 2026 and it is under CNSC review
   • OPG is drawing on more than 7,000 lessons learned from the Darlington refurbishment, and a tunnel boring machine for the 3.4 km condenser cooling water tunnel was due on site for assembly in early 2026

   Additional August 2026 inventory evidence

   GEM August 2026 snapshot: mixed phases. 1200 MW sum of published phase ratings (ratings may mix solar DC/AC). Technologies: Nuclear.

   Compare phase coverage and AC/DC, nameplate and net ratings before combining source figures. This inventory view is not extra capacity to add to the existing project total.
