Procurement for St Thomas Energy Project - Energy as a Service (EaaS) Solution for GSTT

Guy's and St Thomas' Hospital NHS Foundation Trust is seeking a Strategic Energy Partner to engage in a single supplier framework for the decarbonisation of the estate, with St Thomas' Hospital's energy system as an initial anchor project and the opportunity for future projects more widely across the Trust. At St Thomas' Hospital, electricity consumption is estimated to be 51 GWh per year and heat consumption is 37 GWh per year. An Energy as-a-Service model is proposed, with the Energy Service company retaining economic benefits from energy generation and having autonomy over any excess energy generated outside the agreed distribution to the Trust. The Trust intends to award the framework agreement to a sole supplier. The proposed term of the framework agreement is eight (8) years due to the nature of the works involved, the fact they are to be across multiple sites and sequentially and due to the fact that there will be economic and technical benefits to having the same provider deliver the decarbonisation across the entire estate. The supplementary agreements entered into under the framework agreement are proposed to have a longer term of forty (40) years or longer, and the estimated value of £2 billion relates to the longer term. The framework agreement will also be available for use by the other contracting authorities identified within the South East London region, subject to the Trust's prior approval. The call off contracts between the Trust and the supplier appointed to the framework agreement may include a variable mechanism to reflect the volume of energy services provided under the framework agreement.
