  “This contract marks a significant step forward in our transition to renewable energy. Rail is already one of the most sustainable ways to travel, but we recognise there is much more we can do. This agreement with RWE represents a major step towards our ambition to power all our non traction electricity - across offices, stations and depots - from renewable sources by 2030. It also highlights the important role organisations can play in driving investment in clean energy. As we move towards Great British Railways, this deal underlines our commitment to reducing carbon emissions and building a more integrated, sustainable rail network, not just for the millions who rely on it today, but for future generations.”

  “Our purpose is to deliver life's essential service, so our customers, communities and the environment can thrive. We´re committed to reducing our greenhouse gas emissions and transforming the way we generate, purchase and use energy. It takes a significant amount of energy to keep taps flowing and toilets flushing, and energy is one of our greatest costs. Power Purchase Agreements are a mechanism which allow us to buy renewable energy at a fixed cost for a sustained period of time. This agreement will help us manage future planning for energy costs.”
