Plant Description
The facility entered into operation in May 2017 with BWSC chosen as the EPC contractor for the project.
The standard combustion approach is via a standard pusher-type grate technology and boiler supplied by Standardkessel GmbH[5][8].
History
The plant was financed via a £7.5m equity investment for a 40% stake in the plant's holding company, Mersey Bioenergy Ltd (MBL) and was sold by Stobart Infrastructure to MBL for £2m[2].
The plant was also financed by the Green Investment Bank (GIB) (now Green Investment Group (GIG)) who provided 49% of the equity via a £17m mezzainine loan and a £13.2m equity investment via its Foresight UK Waste Resources & Energy Investments (UKWREI)[3].
The remainder of the £42.1 mezzanine finance was provided by GCP Infrastructure Investors. In additon, Investec Bank plc and Eksport Kredit Fonden (EKF) together committed £42.5m of senior loans to the project , while Stobart and Burmeister & Wain Scandinavian Contractor (BWSC), the projects engineering, procurement and construction contractor (EPC) both took an equity stake with commitments of £9.8m and £2.6m respectively[1][2]. The total cost of the project was estimated to be around £110m[3][4].
In 2023 Esken Ltd (formerly Stobart Energy) sold its 39.6% stake to Bioenergy Investment Group (now Evero) for £9m who already held 49.9% of Merseyside Bioenergy Ltd which folowed the aquisition of the Green Invesmtnet Group's holding to Evero in 2017[6].
