Regional Utilities and Wholesale Power Q1 FY2027: Kyuden leads, Hokkaido profit plunges
Companies compared · 5
Takeaway
Revenue rose across the board, but profit outcomes diverged.
In Q1 FY2027, all five regional utilities and wholesale power companies grew revenue, but operating profit rose at three and fell at two. Kyuden led with a 34.9% gain to ¥83.4 billion, while Hokkaido Electric's operating profit fell 44.3% on timing effects.
Industry overview
- Revenue rose year on year at all five companies, with growth ranging from 3.8% at Shikoku Electric to 46.7% at Tohoku Electric. Tohoku Electric's revenue includes self-contracting transactions that have no impact on earnings.
- Operating profit increased at three companies and declined at two. Kyuden rose 34.9%, while Hokkaido Electric fell 44.3%, highlighting the wide gap in performance.
- The timing of fuel cost adjustments influenced earnings. Tariff pass-through and other factors supported Kyuden, while timing mismatches weighed on Hokkaido Electric and Tohoku Electric.
- Expanded wholesale sales also lifted revenue. Shikoku Electric's wholesale sales revenue rose 41.7% year on year, offsetting a decline in retail sales revenue.
- Government support for electricity and gas bills also aided Kyuden. Such measures can support earnings, but their durability warrants attention.
Revenue ranking
Tohoku Electric ranked first in revenue, but a substantial amount came from self-contracting transactions. Revenue scale alone does not show profit-generating ability, so it should be considered alongside profit and margins.
Operating profit ranking
Kyuden led the five companies in operating profit, widening its lead over peers. Tariff pass-through and its power source mix provided support, while fuel cost adjustment timing weighed on Tohoku Electric and Hokkaido Electric.
Operating margin ranking
Kyuden posted the highest operating margin, demonstrating its ability to convert revenue into profit. Tohoku Electric led in revenue but had a lower margin, underscoring the difference between scale and profitability.
Winner and loser
Kyuden was the strongest performer. Operating profit rose 34.9% to ¥83.4 billion, the highest among the five companies. Its 15.7% operating margin also topped the group, ahead of the 12.9% recorded by Shikoku Electric and J-POWER. Tariff pass-through, its power source mix and government support all helped lift profit.
Hokkaido Electric had the toughest quarter. Revenue rose 5.9% to ¥214.5 billion, but operating profit fell 44.3% to ¥24.4 billion and net profit declined 52.0%. A timing mismatch in fuel cost adjustments squeezed earnings.
J-POWER's core operating profit rose 11.7%, but net profit fell 47.3%. The prior-year period included a gain from the sale of an equity stake in its U.S. thermal power business, which did not recur.

Key moves and strategy
- Tohoku Electric posted the biggest revenue increase among the five, driven by expanded trading outside its home region. Self-contracting transactions totaled ¥155.1 billion, up ¥147.3 billion from a year earlier. The same amount is recorded in costs, limiting the earnings contribution. Lower output at the Onagawa No. 2 reactor also weighed on profit.
- Kyuden ranked first among the five in operating profit, net profit and operating margin. Tariff pass-through related to fuel cost adjustments and government support helped its generation and sales business.
- Shikoku Electric's wholesale sales revenue rose 41.7% year on year. Retail sales revenue fell 9.1%, with wholesale growth making up the difference.
- Hokkaido Electric increased revenue through higher sales under bilateral contracts. But the timing mismatch in fuel cost adjustments dragged on earnings, preventing revenue growth from translating into higher profit.
- J-POWER increased operating profit 11.7% year on year, helped by a higher thermal power utilization rate and increased overseas sales. Net profit declined as the prior-year gain from a sale fell out of the comparison.
Common industry risks
- Fuel prices and delays in passing costs through to tariffs remain risks. Timing mismatches reduced earnings at Tohoku Electric and Hokkaido Electric, leaving profit exposed to changes in fuel markets.
- Wholesale power market prices and trading volumes can affect returns. Expanding wholesale sales creates opportunities, but market-price volatility can make profitability less predictable.
- Power plant operating conditions matter. Lower output at Tohoku Electric's Onagawa No. 2 reactor weighed on profit. Generation below plan can affect earnings.
- Changes to government bill-support programs are another risk. Where support bolsters revenue, as at Kyuden, companies must also consider the impact when the programs end.
- Retail competition and sales volumes remain important. Shikoku Electric's retail sales revenue declined, offset by growth in wholesale sales. Retaining its customer base remains a challenge.
Ranking shifts and structural trends
Tohoku Electric led in revenue, but the contribution from self-contracting transactions was substantial, making revenue alone an imperfect measure of business scale. Kyuden topped the operating profit ranking, showing that revenue size and profit-generating ability do not necessarily align.
The five companies' average operating margin was 12.1%. Kyuden's 15.7% was above the average, while Tohoku Electric's 7.7% was below it. Average revenue growth was 15.1%, lifted by Tohoku Electric's strong increase.
For job seekers and career changers
Work at an electric utility involves more than operating power plants. Wholesale trading, balancing supply and demand, tariff systems and customer relations also shape business performance. This quarter, expanded wholesale sales at Shikoku Electric and trading outside Tohoku Electric's home region were reflected in the results.
Because fuel markets and regulatory changes can directly affect earnings, technical employees also need to understand markets and policy. Investors should look beyond revenue to margins and the factors behind changes in profit.
Revenue growth year on year
Tohoku Electric's sharp increase lifted the group average. Self-contracting transactions are matched by an equal amount in costs, so they should be distinguished from underlying sales growth.
Net profit growth year on year
Net profit increased at Kyuden and Shikoku Electric, while Hokkaido Electric and J-POWER recorded steep declines. Fuel cost adjustment timing and the absence of one-off gains from the prior-year period widened the gap.
