A Czech utility reveals the effects of a chip production slowdown

A Czech utility spent heavily preparing a building and electricity infrastructure for a semiconductor customer expected to expand production. Its annual report now records that the planned production ramp-up did not materialise and work in the building was gradually stopped. The account offers a view of industrial investment risk from the businesses surrounding a chipmaker. ^{[21] [25]}

Energoaqua supplies energy, water and technical gases and rents property in the industrial park at Rožnov pod Radhoštěm. The town is also home to onsemi’s operations. In June 2024, the US chipmaker announced plans for an investment of up to $2bn in integrated silicon-carbide production in the Czech Republic, subject to regulatory and incentive approvals. The announcement presented a planned multiyear expansion, rather than completed investment. ^[23]

The local preparations involved smaller but substantial commitments. Energoaqua's 2024 report recorded CZK220m spent on V1 reconstruction and CZK76.2m on substation expansion linked to customer requirements. Those two amounts total CZK296.2m. The upgraded electricity facilities also served the wider industrial network, so the whole sum cannot be treated as a loss attributable to one customer. ^[25]

In its 2025 annual report, published this April, Energoaqua said the V1 tenant, onsemi, had been expected to reach full production during 2025 and 2026. The ramp-up had not been confirmed in the first quarter of 2026 for reasons on the customer side, it said, and production in the building had gradually stopped. That statement concerns V1. It does not establish that onsemi ceased operating in Rožnov or cancelled the entire proposed Czech expansion. ^[21]

The report also described deferred utility investments. A planned additional hydrogen generator was postponed indefinitely after the expected customer investment failed to materialise, while an expansion of demineralised-water production was paused pending clarification of requirements. The company said future investments for the facilities planned by the customer would depend on binding contractual commitments. ^[21]

The first-half 2026 accounts show weaker revenue in the utility businesses. Energoaqua reported water-segment revenue down 15.9 per cent and energy revenue down 10.7 per cent from the comparative period. Group profit was CZK173.5m, down 13.9 per cent. The figures are revenue and accounting profit, not a measurement of water or electricity volumes, and the interim accounts were unaudited. ^[22]

The numbers also show an offset. Revenue from property activities rose 25.9 per cent, supported by a new building in Prague. Energoaqua continued to report a substantial profit and said it expected to operate in the same fields and on a similar scale in the second half. Its disclosures therefore describe pressure on part of a diversified business rather than a company brought to a halt. ^[22]

There was a separate sign of restructuring at the chipmaker. Eurofound's European Restructuring Monitor recorded an announcement of 200 planned job reductions at the Rožnov facility in May 2026, citing weaker semiconductor demand. Its entry is a compilation of reported restructuring, rather than a measure of the investment outcome or confirmation that every announced reduction was completed. ^[24]

The commercial exposure extends beyond the capital budget of a chipmaker. A utility may need to build capacity before a customer can use it, tying its own returns to an expected production schedule. Buildings and networks can retain alternative uses, while minimum-payment commitments or compensation clauses may protect some of the spending. Their terms determine how much risk the supplier actually carries.

Energoaqua's accounts do not establish that onsemi caused all of the decline in utility revenue or that the V1 spending must be written off. They do establish a gap between the production anticipated when facilities were prepared and what the utility later reported. The contracts governing that gap will determine who pays for the unused capacity and how much of the investment can earn a return elsewhere.
