TagEnergy is a clean energy enterprise for a new cycle in the renewable energy industry. It was formed in 2019 to accelerate the energy transition by developing and investing in competitive and clean power stations in order to compete directly and actively on the energy markets.

Renewables have now become the main source of energy able to provide both social responsibility and price efficiency, and we are delivering this in the countries where we have established our activity.

​ TagEnergy is operated by a highly-experienced team of manager-shareholders. Its operations span the renewables value chain, from development, financing, construction and asset management of wind, solar and storage projects, to commercialisation of its competitive energy.

TagEnergy has assembled a portfolio of more than 6 GW in the UK, Australia, Spain, Portugal and France, and intends to drive the pace of transition through projects that deliver reliable energy affordably, and at scale.
