Power Business

We are a leading player in the IPP (Independent Power Producer) business, with a proven track record and extensive assets worldwide.  As well as conventional power plants we are active in renewable energy such as offshore wind and solar power.


Developing a presence in Portugal

Marubeni entered the Portuguese domestic electricity supply business in October 2013, by acquiring 50% of TrustEnergy, a power generation asset portfolio with the second highest generation capacity in the country, from Engie (formerly GDF Suez).

TrustEnergy’s power generating assets consist of natural gas-fired combined-cycle plants, coal-fired plants and wind farms, producing about 15% of the total power used in Portugal.
