Data Centres: Boom and Backlash

Oregon PUC delays its data-centre tariff

The Oregon PUC delayed Portland General Electric's 29% large-load rate rise and the matching 1.3% household cut to 7 July, citing 200 pages of tariff updates staff had not yet reviewed.

Key takeaway

Oregon's data-centre tariff is filed but frozen until 7 July, so the cost shift onto operators exists only on paper.

Oregon's Public Utility Commission (PUC, the state regulator that sets electricity rates) delayed Portland General Electric's (PGE) proposed 29% large-load rate rise, and the matching 1.3% household bill cut, to a decision on 7 July 1. PUC chair Letha Tawney cited roughly 200 pages of tariff updates that staff needed time to review. PGE had filed the rise under the Oregon POWER Act, a state law that attributes grid-reinforcement costs to large loads such as data centres, and it filed as the first US utility to turn such a law into an actual tariff .

Neither side of the tariff has taken effect. The 29% increase and the residential reduction are both on hold, which means the precedent everyone cited, that operators rather than households absorb grid costs, exists on paper and nowhere else. A delay is not a defeat, but it is not the clean win the framing implied either. If the commission trims the 29% figure on 7 July or reopens the cost-attribution method, Oregon's claim to be first to implement the mechanism narrows to first to file it.

The stall mirrors the procedural friction holding up Virginia's capacity fee, where a cancelled session rather than a hostile vote is what blocks the charge. Both instruments now wait on a calendar rather than a count of yeses and noes, and both aim at the same large data-centre loads. The mechanism advances even where no decision has landed, which is a different kind of progress from a vote won.

Deep Analysis

In plain English

Oregon has a law called the POWER Act (Prioritising Operational and Wholesale Energy Responsibility) that says electricity companies must charge big users, like data centres, the true cost of the extra grid upgrades needed to serve them, instead of spreading those costs across ordinary households. Portland General Electric (PGE), the main electricity company in the Portland area, filed a plan to raise rates for large data centres by 29% and cut household bills by 1.3%, putting the Oregon law into practice for the first time in the US. The state's Public Utility Commission (PUC), the regulator that must approve this kind of rate change, asked for more time to study the 200-page filing and set 7 July as its new decision date. No bills have changed yet. The delay means everyone is waiting to see whether Oregon's regulator actually approves the model, which would give 12 other US states that are considering similar laws a real-world example to point to.

Deep Analysis
Root Causes

Two structural gaps explain why Oregon needed the POWER Act at all. First, utility tariff law in the US defaults to average-cost pricing: all customers in a rate class pay the system-average cost of serving them, even when a single customer class drives the majority of new infrastructure investment.

Data centres above 20 MW drew enough load growth in PGE's service territory to require substation upgrades whose cost, under the pre-POWER Act default, would have been spread across PGE's 900,000 residential customers.

Second, FERC's jurisdiction over wholesale electricity transmission means that a state regulator can only set the retail rate; it cannot compel FERC to attribute transmission upgrade costs in a particular way. The POWER Act is a retail-side instrument operating within that boundary.

Its enforceability depends on the PUC approving the tariff filing and on no party successfully invoking FERC jurisdiction to preempt the state rate structure, a risk that becomes more concrete once FERC acts on RM26-4-000.

What could happen next?
  • Precedent

    A 7 July PUC approval of PGE's tariff would give 12 other states carrying active cost-attribution bills a filed, approved tariff with specific rate figures to cite in their own proceedings.

  • Risk

    If a PUC modification reduces the 29% figure materially, operators will use the revised number to argue that a properly calibrated cost-attribution tariff imposes less than half the headline rate, undercutting the deterrent effect in other states.

Antel will build a $70m AI data centre in Canelones, announced after an 11-12 August Council of Ministers meeting, with construction from Q1 2027 and roughly 250 direct jobs. Uruguay is putting a sovereign AI facility on the state balance sheet rather than courting a hyperscaler to build one.

Abbott directed PUCT and ERCOT on 3 August to audit every queued data centre's ownership, incentives and water use, saying projects that fail the state's survey should lose grid access. QTS's co-chief executives welcomed the review; Agriculture Commissioner Sid Miller called it too vague and wants a special legislative session instead.

AEMC advised ministers on 5 August that data centres should surrender renewable certificates against actual consumption, prove new demand with new firm capacity, and register as market participants. The advice would turn passive customers into obligated participants inside the market's dispatch and settlement machinery, ahead of an access-standards determination due in late October.
