At Octopus Energy Generation (OEGEN), we’re driven by a mission to power a sustainable future. As innovators in renewable energy, we invest not only in large-scale clean energy projects but also in people, communities, and a greener world.

Since entering the renewables sector in 2010, we’ve rapidly become a leading onshore wind investor across mainland Europe, the largest solar power supporter in Europe, and are now expanding enthusiastically into offshore wind. We currently manage more than £7 billion in renewable energy assets worldwide.

Our growing portfolio includes over three hundred major energy-producing companies, ranging from wind farms to solar plants, with new initiatives in energy storage and hydrogen progressing fast. As we continue to expand, we’re seeking passionate individuals to join our diverse and committed team to help shape the future of renewable energy.
