Turbogás was created in November 1994 with the objective to develop the Tapada do Outeiro Combined Cycle Gas Turbine (CCGT) power plant.

The construction of the Tapada do Outeiro played a fundamental role in the introduction of natural gas as an alternative fuel source in Portugal. The demand from the plant, which on entry into full commercial operation reached 70% of the natural gas imported into the country, provided the basis for the economics of the gas pipeline.

In November 2004, International Power acquired Tapada do Outeiro's project and due to the acquisition of International Power by ENGIE, nowadays Turbogás is a company totally owned by TrustEnergy.


Turbogás is responsible for the management of the Gas Supply Agreement (GSA) with Transgás, the Power Purchase Agreement with REN (the off-taker) and the Operation and Maintenance Contract with Portugen.

Such as to TrustEnergy, safety, environment and the relation with the community are core issues as well to Turbogás.

We believe that in what concerns environmental issues, it is essential to take into account our legal obligations as an integral part of our values. We are aware of the interaction between the activity carried out and the environment, as well as the importance of our contribution to the preservation of the same.

We apply the highest safety standards to ensure that the working environment in Tapada Outeiro presents minimal risk to health and safety of staff, contractors, visitors and the public.

To Turbogás, participating in the activities of the local population is something very important. We intend to pursue a policy of "good neighbourhood" with the Municipalities, Parish Councils, schools and fire brigades. We are proud to contribute to civic and educational activities.

Both environmental and safety activities are dully certified by the international standards.

TrustWind is the company responsible for managing the wind power assets fully owned by TrustEnergy.

Previously known as Lusovento Holding, it was created in June 2013, after the Joint-Venture between ENGIE and Marubeni was formalised. It recently changed its social designation to TrustWind.

The experience of the company in Portugal dates back to 2009, when ENGIE, after investing in the wind power sector in Portugal, in 2005 and 2007, through the acquisition of four wind farms, decided to administer and manage the wind farms directly through its branch in Portugal.

Nowadays, TrustWind manages a set of twelve wind farms, scattered from north to the south of the country, totalizing 489 MW: Terra Fria, in the district of Vila Real; Carreço-Outeiro II, in the district of Viana do Castelo; Terras Altas de Fafe, in the district of Braga; Mourisca e Nave, in the district of Viseu; Serra do Ralo, Prados, Mosqueiros II e Vale de Estrela, in the district of Guarda; Bravo e Mougueiras, in the district of Castelo Branco; and Baixo Alentejo/Mértola, in the district of Beja.


TrustWind complies with the highest standards in what concerns health and safety and environment, having its occupational health and safety management system and environmental management system certified by the international standards: ISO 45001 and ISO 14001.

Environmental protection is a constant concern in TrustWind’s activities.

Besides the compliance with the regulation in place, TrustWind aims to promote activities with the community not only to strengthen the relationship with local community, through the organization of pedestrial tours and fiel trips to the wind farms, but also to promote a greater knowledge about environmental issues, as the respect for the ecosystems surronding the wind farms.

Tejo Energia is a joint-venture between TrustEnergy, with a 56.25% stake, and Endesa Generación with 43.75%.

EDP started the construction of units 1 and 2 of coal fired Pego Thermal Power Plant in 1987. In 1990, as part of a Government initiative to restructure EDP and to encourage private sector investment in the electricity sector, units 1 and 2 were marketed for sale in an international bid.

Thus, Tejo Energia was created as owner of Pego Thermal Power Plant. Subsequently two other limited liability Project companies were incorporated: Pegop and CarboPego, to operate and supply coal to Pego respectively.


Tejo Energia is responsible for the management of the Power Purchase Agreement with REN (the off-taker), the Operation and Maintenance Agreement with Pegop, the Coal Delivery Agreement with CarboPego and some other contracts related to the project, as well as managing the relation with banking institutions, strategic planning and shareholders relations.

Pego Thermal Power Plant has its Environmental and Safety management systems certified – respectively ISO 14001:2004 (Pego was the first industrial facility in Portugal to be awarded with this certification) and OHSAS 18001:2007, through Pegop. These systems are part of the commitment to provide the workers with a safe and healthy working environment and to ensure that all operations are performed at the highest standards for the environmental protection and the safety of the neighbour community.
