A newly created large-load rate class, approved May 2026 applies once the Oregon PUC's May 2026 approval of Portland General Electric's new large-load rate class takes effect, building on PGE's 2025-approved changes to new-load connection cost policy. PacifiCorp has separately proposed Schedule 401, a new customer class for large energy-use facilities, alongside new large-customer line-extension charges approved as part of its own rate review.
Also active in Oregon: PGE has already used a 31 MW customer-sited battery to unlock 80 MW of additional data centre capacity in 2026 without new generation, and is serving an Aligned Data Centers project in Hillsboro alongside a $3 billion Lam Research semiconductor lab expansion in Tualatin.

Figures compiled from the Edison Electric Institute's "Large Load Projects and Tariffs" (September 2026) member-company summary and public regulatory filings. Confirm current tariff terms directly with Portland General Electric / PacifiCorp and the relevant state public utility commission before relying on any figure for a capital decision.
Weighing Oregon against another state or a Canadian province with a different rate and interconnection picture entirely? Run both sides of the comparison through our licensed AI data centre cost configurator — it applies each jurisdiction's actual power rate, tax treatment and large-load tariff rules to the same seven build configurations.
Model This State on Your Own Site
Every figure above comes from the same power-cost and tariff dataset behind the SCR AI Build Configurator — a licensed, embeddable widget that models seven data centre build configurations against all nine Canadian provinces and all 50 US states plus DC, returning capital expenditure by line item, energy cost, revenue by commercial structure, EBITDA and payback.
| Licence | Price (CAD) | Who it suits |
|---|---|---|
| Standard | $4,000 / domain / year | Advisors who need three lease-model configurations and a clipboard summary |
| Pro | $10,000 / domain / year | Consultants who send CSV deliverables to clients and want all seven configurations |
| Enterprise | From $25,000 / year, up to 3 domains | Developers and EPC firms who want the model on their own cost basis with attribution removed |
Not ready for an annual licence? A one-time Site Screening Report ($950, one site) runs the same model for a single build without embedding anything.
