Duke Energy's Heat Wave Message: Save Power, While We Collect Dividends

As a heat wave hits the Carolinas, Duke Energy asks customers to conserve and warns of higher bills, yet the utility's own spending records show decades of underinvestment in the grid that leaves it vulnerable under stress.

WRAL reports that Duke Energy is prepared for this week's heat wave and does not expect brownouts, but warns customers their bills will rise if they don't conserve energy.^[1] The utility's message is familiar: you manage your thermostat while it manages your rates. But the real story isn't about your AC setting. It's about what Duke has collected from ratepayers for grid maintenance and what it has actually spent.

Every dollar Duke collects for vegetation management, pole inspection, and distribution automation is supposed to keep the grid reliable. Yet independent analyses and the utility's own filings show a pattern: depreciation and maintenance allowances are collected in rates, then underspent, with the cash flowing to shareholders as dividends. When a storm or heat wave exposes the deferred maintenance, the company asks for a 'hardening' surcharge, effectively billing customers twice for the same infrastructure. The canonical precedent is PG&E's wildfire record and Texas's 2021 blackout, where under-maintained monopoly infrastructure killed people. Duke's grid, much of it built decades ago, struggles with outdated poles and insufficient vegetation management.^[9]

Duke Energy set a preliminary summer peak record of 35,269 MWh on June 24, 2025.^[4] The company has prepared for this heat wave, but the question is whether its preparation includes spending the money it collected for reliability. In 2024, Duke spent $4 billion on grid investments,^[9] but against what was collected? The accountability chart, SAIDI/SAIFI versus dividend payout and rate growth, is the tool to answer that. Municipal and cooperative utilities, which have no shareholders, consistently achieve better reliability per dollar spent. They are the natural control group, and their record defeats the excuse that Duke's territory is uniquely hard to serve.

The Department of Energy issued an emergency order for Duke Energy during this heat wave, noting that some generating units were limited by environmental permits.^[5] That order is a symptom of a system pushed to its margin by decades of prioritizing shareholder returns over physical resilience. The remedy is not a new surcharge. It is a prudence review of past maintenance spending, a performance-based reliability standard with symmetric penalties, and a docket where customers can demand that the money they already paid for a reliable grid actually be spent on it.

The North Carolina Utilities Commission should open a prudence review of Duke Energy's distribution maintenance spending over the past decade, comparing collected depreciation and O&M allowances against actual vegetation management, pole inspection, and distribution automation expenditures. It should also establish a performance-based reliability mechanism that puts a portion of Duke's allowed return at risk against SAIDI and SAIFI targets, with symmetric rewards and penalties, removing the incentive to underinvest in maintenance.

Elena covers the gap between what monopoly utilities collect to maintain the grid and what they actually spend on it. The dividend gets paid on time, she notes; the line crew doesn't always show up. Her beat is outages, deferred maintenance, and the neglected equipment that sparks wildfires and kills people. She sets a utility's reliability record against its shareholder payouts, digs the shrunken tree-trimming and inspection budgets out of the company's own filings, and treats storm-hardening surcharges skeptically when ratepayers already paid to maintain the same poles once.
