Japan's Big 3 Electric Utilities Q1 FY2027: Kansai leads as core earnings diverge

All three companies reported higher revenue than a year earlier. Average revenue was ¥1.105 trillion, and average growth was 5.6%. But higher sales did not translate into stronger core earnings.

• Rising fuel costs squeezed margins across the group. At TEPCO, higher fuel and depreciation costs pushed operating results into the red.
• A lag in the fuel cost adjustment mechanism also weighed on earnings. At Chubu Electric and Kansai Electric, the delay in reflecting fuel price changes in rates hurt profits.
• Kansai Electric was the only company to post an operating profit, at ¥20.4 billion. Chubu Electric recorded an operating loss of ¥25.1 billion, while TEPCO's loss was ¥34.3 billion. The three-company average was a loss of ¥13.0 billion.
• Net income diverged for reasons beyond core operations. A share sale gain lifted Kansai Electric's result, while Chubu Electric's net income fell 58.7% year on year. TEPCO's net loss narrowed sharply after a disaster-related special loss booked a year earlier did not recur.

The results show how fuel prices and rate mechanisms can keep earnings volatile even as revenue grows.

Kansai Electric had the strongest core performance. Revenue rose 9.8% year on year to ¥1.008 trillion, the fastest growth among the three, and the company stayed in the black with operating profit of ¥20.4 billion. Its operating margin was 2%, above Chubu Electric's negative 3%.

Still, Kansai Electric's operating profit fell 84.2% from a year earlier. Net income increased 38.2% to ¥137.1 billion, but a substantial one-time gain from a share sale contributed to the increase. Net income alone is therefore not a reliable gauge of the company's underlying strength.

TEPCO had the toughest quarter. Its revenue was the highest of the three at ¥1.4812 trillion, up 3.9% year on year. But it posted an operating loss of ¥34.3 billion, ¥9.2 billion more than Chubu Electric's loss. TEPCO recorded a net loss of ¥9.8 billion, far narrower than the ¥857.7 billion loss a year earlier, mainly because the prior-year disaster-related special loss did not recur.

Chubu Electric also posted higher revenue, up 3.2% to ¥825.8 billion, but recorded an operating loss of ¥25.1 billion. Higher fuel costs and delays in passing them through to rates weighed on earnings.

Kansai Electric recorded a ¥105.1 billion special gain from a transaction involving shares in Kinden, an equity-method affiliate. The gain boosted net income, but it was one-off and should be distinguished from recurring earning power. The company's full-year forecast calls for revenue of ¥4.5 trillion and operating profit of ¥250 billion.

Chubu Electric forecasts full-year revenue of ¥3.9 trillion, up 10.0% from the previous year. Its latest materials did not provide a full-year operating profit forecast. After its first-quarter operating loss, investors will be watching for improvement in fuel costs and the impact of the rate system.

TEPCO did not provide a full-year forecast in the data available for this comparison. Revenue grew in the first quarter, but the company still posted an operating loss. Its challenge is to restore profitability in its power business by controlling fuel and depreciation costs. The data do not include comparable information on major investments or new businesses.

• Fuel price volatility: Higher prices for LNG, coal and other fuels raise generation costs. Even when prices stabilize, there can be a delay before changes are reflected in rates.
• Rate mechanisms: Fuel cost adjustment systems and regulatory changes can prevent companies from passing higher costs on to customers immediately.
• Heavy fixed costs: Depreciation and other costs can weigh on profits even when sales volumes and revenue increase.
• Reliance on one-off gains: Special gains such as Kansai Electric's share sale proceeds may not recur in subsequent periods.
• Power mix and competition: The operating status of generation assets and competition in electricity sales affect each company's costs and earnings.

Work at an electric utility extends beyond power generation and transmission. Roles in fuel procurement, rate design, asset management and regulatory compliance all help support profitability.

This quarter showed that revenue size alone is not a reliable measure of a company's condition. When comparing employers, job seekers should look at power generation mix and capital investment, as well as fuel cost management and sources of earnings. Data analysis and the ability to interpret regulation are valuable across a wide range of roles in the industry.
