CRCCarbon Reduction Commitment

The Carbon Reduction Commitment (CRC) is an innovative climate change and energy saving scheme for the UK. It will encourage improvements in energy efficiency which can save organisations money. The scheme has been designed to generate a shift in awareness in large organisations especially at senior level, and to drive changes in behaviour and infrastructure.

The scheme is also a central part of the UK’s strategy for controlling our carbon dioxide (CO2) emissions. It will tackle CO2 emissions not already covered by Climate Change Agreements and the EU Emissions Trading System. This will help reduce the country’s carbon footprint to deliver the ambitious emissions reduction targets set in the Government’s Climate Change Act. The scheme started in April 2010.

DSRDemand Side Response – involves electricity users varying demand due to changes in the balance between supply and demand, usually in response to price.
DUOSDistribution Use Of System Charges – The DUoS charge covers the cost of receiving electricity from the national transmission system and feeding it directly into homes and businesses through the regional distribution networks. These networks are operated by Distribution Network Operators (DNOs) such as Central Networks. The distribution networks include overhead lines and underground cables, as well as substations and transformers, which reduce the electricity’s voltage to safe levels for use in homes and businesses.

ESOSEnergy Savings Opportunity Scheme

ESOS is a mandatory energy assessment scheme for organisations in the UK that meet the qualification criteria. The Environment Agency is the UK scheme administrator.

Organisations that qualify for ESOS must carry out ESOS assessments every 4 years. These assessments are audits of the energy used by their buildings, industrial processes and transport to identify cost-effective energy saving measures.

FFiTFeed-in Tariff – Feed-in Tariffs (FITs) is a UK Government scheme designed to encourage uptake of a range of small-scale renewable and low-carbon electricity generation technologies. introduced on 1 April 2010, under powers in the Energy Act 2008. The UK Government’s Department of Business, Energy and Industrial Strategy (BEIS) makes the policy decisions about the FITs scheme and are the relevant contact for queries about legislation. The energy regulator Ofgem E-Serve administers the scheme. Visit the website here.
