Network Rail is undertaking a market engagement exercise to enhance its understanding of the market for the supply and delivery of liquid fuels across Great Britain. The information gathered will be used to inform the Network Rail’s procurement strategy and any future procurement activity. Network Rail is intending to tender for a national framework for the supply and delivery of liquid fuels across Great Britain. The framework will enable Network Rail and authorised users to procure liquid fuels required to support the operation of rolling stock and associated assets located throughout England, Scotland and Wales with an initial term of eight years, with break clauses applying throughout the term. The proposed framework is expected to include: • Supply and delivery of red diesel, white diesel and gas oil. • Supply and delivery of alternative and renewable fuels, including Hydrotreated Vegetable Oil (HVO) and Fatty Acid Methyl Ester (FAME). • Emergency and ad-hoc fuel deliveries. • Nationwide coverage across approximately 50 fuel locations throughout Great Britain. • Fuel management solutions, including telemetry and automated fuel ordering systems. • Fuel monitoring, reporting and management information. • Tank security and access-control solutions to support fraud prevention and fuel security. • Transition and data migration support where required. • Associated customer service, account management and performance reporting. Suppliers will be required to ensure all fuels supplied comply with all applicable legislation, industry standards and regulatory requirements. The framework is expected to operate on a demand-led basis with no guaranteed volume commitment.
