Summary

Before
Estimated buildout target through 2030
2027. Northland’s Q2 2026 update reports 71 of 73 turbines installed, 59 generating and full commercial operations targeted for 2027.
Construction is verified; the completion date remains an estimate. The timeline marker represents the published target year/month, not a confirmed opening day.
Published cost and electrical output
Project cost / investmentAbout CAD 9 billionCost scopeFull-project capital cost in Canadian dollars; not project debtCost source date2023-09-22Electrical generating capacity1,022 MW — 294 + 728 MW contracted output, total 1,022 MW; operator rounded 1 GWVerified project stagePartly operational / under construction
Project-specific research
Northland September 22, 2023 publishes approximately C$9 billion total capital cost for Hai Long, separate from its C$5 billion financing. Published project portions are 294 MW and 728 MW, totaling 1,022 MW; the operator rounds the complex to 1 GW. Older inventory 1,044 MW reflects a different turbine/project rating and is not additive.

Northland Q2 2026 release confirms 71 of 73 turbines installed and 59 generating; full commercial operation remains targeted for 2027. Overall costs are described as aligned with original expectations.
Scope and evidence
Retained only with documented physical construction, commissioning or 2025–2026 opening and published project-specific costs and electrical output. 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.

Suggest a correction

Something missing or wrong? Say it in your own words: a link that backs this pin up, a different start or end date and why, or a fact it lacks or gets wrong. The AI checks it against this pin's sources, searches for better ones, and adds any page that backs you up. The pin's own sources still count most. A picture that shows something else, or shows it badly, is looked at too, and moved down or replaced.
