The British Industrial Competitiveness Scheme (BICS) is a key component of the government's UK Modern Industrial Strategy aimed at improving the international competitiveness and profitability of eligible UK businesses by reducing certain electricity policy costs recovered through electricity bills. Through exemptions from the costs associated with the Renewables Obligation (RO), Feed-in Tariffs (FiT) and Capacity Market (CM), BICS is intended to reduce electricity costs for eligible businesses operating in specified frontier and foundational industries. Although the principal beneficiaries of BICS are energy-intensive manufacturers, the scheme has wider implications across the electricity sector. It affects electricity suppliers responsible for administering the exemptions, developers and operators of energy-intensive industrial projects, manufacturers of components used in energy infrastructure, and parties negotiating electricity supply agreements, private wire arrangements and co-location projects. This Practice Note explains how BICS operates, the eligibility criteria, the level of relief available and the implementation timetable. It also considers the interaction between BICS and the Energy Intensive Industries (EII) scheme and the British Industry Supercharger, together with the key practical implications
