CMCapacity Market. The Capacity Market forms part of the government’s Electricity Market Reform policy. It is intended to incentivise investment in more sustainable, low-carbon electricity capacity at the least cost for energy consumers. This is needed to help secure electricity supplies for the future.

CRCThe CRC Energy Efficiency Scheme was a mandatory carbon emissions reduction initiative that applied to large organisations in the public and private sectors in the UK. It was implemented in 2010 to incentivise energy efficiency and cut emissions in large energy users in the UK.

The scheme required participants to measure and report their electricity and gas supplies on an annual basis to the CRC registry. The Carbon Reduction Commitment (CRC) Energy Efficiency Scheme is now closed.

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.

Energy StatementAn Energy Statement is often required by Local Authority planning as part of a new build planning submission or Design and Access Statement, in conjunction with your BRUKL report. Your Energy Statement demonstrates how the energy efficiency of the proposed development meets relevant Local Authority requirements over and above those of BRUKL, and can include your plans for reducing carbon emissions, generating renewable energy, and the overall energy demand.

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.
