Alstom said on 20 October 2026 that it had commissioned a 1 MW solar park at its Mátranovák factory in Hungary. The company expects the installation, covering about 7,000 square metres, to generate 1,700 MWh annually and supply more than 20% of the site’s electricity consumption. Generation began after nearly two years of planning, permitting and construction.

Alstom estimates that onsite generation will avoid about 260 tonnes of carbon dioxide emissions a year. The project was developed under a long-term onsite power purchase agreement between Alstom and E.ON. The Mátranovák plant makes bogie frames for metro and railway vehicles; the announcement did not disclose the project cost or electricity purchase price.
