Swan Energy Ltd work with Hull and East Yorkshire Hospitals NHS Trust managing two hospital's EU ETS reporting obligations. Hull Royal Infirmary were a CRC participant, with the compliance obligations of the scheme managed by Swan Energy on their behalf. After the installation of a new generator the hospital exceeded the 20MW thermal input capacity inclusion criteria for EU ETS. Swan Energy managed the transition from CRC to EU ETS. As such the two hospitals, Castle Hill Hospital and Hull Royal Infirmary, have differing reporting obligations due to one being an EU ETS opt out and the other a full participant. Using Swan Energy to manage reporting obligations reduces complexity for the trust and as a result the Trust has met all their EU ETS compliance obligations to present.
