1 [Business Intelligence Statistical Bulletin June 2015 Non Domestic energy consumption 2013 Kent Local Authorities (Previously Industrial & Commercial energy use) Related documents Domestic energy consumption Commercial Information monitoring Climate Change Act Environmental Policies Note; In this bulletin Kent refers to the Kent County Council (KCC) area which excludes Medway. This bulletin presents the 2013 gas and electricity energy consumption for non domestic users in local authority districts in Kent. The series previously published as Industrial and Commercial energy consumption has been revised and published by the Department of Energy and Climate Change (DECC). Climate change and the Earth s resources have become a high profile issue. Individuals, households, businesses, organisations and interest groups are currently faced with increasing pressure from regulators and pressure groups to improve energy consumption and environmental performance. Further details can be found on page 8 of this bulletin Further information Business Intelligence Research & Evaluation Kent County Council Sessions House Maidstone Kent ME14 1XQ research@kent.gov.uk Tel: Total non domestic energy consumption (gas and electricity together) in Kent, during 2013, was estimated to be 664,037 kwh per consumer unit. This is 5.7% higher than the previous year and 15.0% lower than 5 years ago. Nationally consumption changed by -2.2% and +3.2% respectively over the same period. The total non domestic energy consumption for each gas consumer unit (meter) in Kent during 2013 was estimated to be 597,878 kwh. This is 4.2% lower than the previous year and 25.6% lower than 5 years ago. The total non domestic energy consumption for each electricity consumer unit (meter) in Kent during 2013 was estimated to be 66,159 kwh. This is 1.8% more than the previous year and 6.3% lower than 5 years ago.

2 Non Domestic energy total consumption summary The total energy consumption per non domestic consumer units in Kent (KCC area) during 2013 was estimated to be 664,037 kwh (gas and electricity taken together). This is a 5.7% rise on the previous year. However, it is lower than the national average for England which was 716,576 kwh. (Table 1). Consumption varied across the county with non domestic users in Gravesham district using an average 1,605,186 kwh of which 94% was gas energy; in contrast to Sevenoaks district where average consumption was 271,803 kwh of which 83% was gas. The average for the Medway area was 507,522 kwh (Table 1). Average gas consumption per non domestic meter in Kent, measured in kwh, was 9.04 times electricity consumption; 597,878 kwh of gas compared to 66,159 kwh of electricity (Table 1). Non Domestic energy gas consumption summary Three local authority districts across the county (Ashford, Gravesham and Shepway) have seen increases in the amount of gas energy used compared to the previous year. However, over a five year period non domestic use in Dover district has been reduced by 71%; nationally there has been an increase of 4% (Table 2). Three of the twelve Kent districts (Dover, Gravesham and Swale) were above the National average (642,539 kwh) for gas consumption (Table 2). In 2013 there were 5,813 non domestic gas meters in Kent (KCC area) compared to 57,240 electricity meters (Tables 3 and 5). Non Domestic energy electricity consumption summary Average electricity consumption per consumer unit in Kent was 66,159 kwh of electricity. This is 1.8% higher than the previous year, however, it is about 11% lower than the national average (74,037 kwh) (Table 4). Six local authority districts across the county (Canterbury, Dartford, Gravesham, Sevenoaks, Shepway and Tunbridge Wells) have seen reductions in the amount of electricity energy used compared to the previous year. In addition one district (Tonbridge and Malling) showed almost no change (Table 4). Seven of the twelve Kent districts (Ashford, Canterbury, Dover, Shepway, Thanet and Tunbridge Wells were below the National average (74,037 kwh) for electricity consumption (Table 4). Page 2

8 Background information on domestic energy consumption Businesses, individuals, organisations and interest groups are currently faced with increasing pressure from regulators and pressure groups to improve environmental performance. Climate change has become a high profile issue with the UK Government setting a framework for CO 2 reduction up to 2050 through the Climate Change Act 2008 (amended 2010). Generally people are aware of greenhouse gases and that they are found naturally in air. They include carbon dioxide (approx 80% of the total greenhouse gasses), methane (10%), nitrous oxide (6%) and fluorocarbons (5%). These gases trap heat in the atmosphere and keep the earth's surface much warmer than it would be if there was no atmosphere. This warming is known as the greenhouse effect. In the last 200 years, the amount of greenhouse gases in the air has been increasing. The biggest contribution to global warming is carbon dioxide. The way we use energy in buildings causes emissions of carbon. The energy we use for heating, lighting and power in homes produces over 25% of the nation s carbon dioxide emissions, other buildings produce a further one-sixth (17%). However, energy efficiency isn t just about saving the planet s resources and climate change. It is also about saving money. As a result, energy efficiency in the home is one of the Government s main areas of focus for action on climate change. Sources of information Department for the Environment Food and Rural Affairs (Defra) Department of Communities and Local Government (DCLG) Department for Energy and Climate Change (DECC) Measuring and monitoring emissions Measuring, monitoring and comparing energy consumption is relatively new. Statistics at local authority level which provide a time series and enable comparisons between local authorities have, in some instances, particularly for the gas and electricity industries only recently been published. Please note information should be used only as a guide as some of the information is estimated, albeit in the most scientific manner. kwh The kilowatt hour, (symbol kwh) is a unit of energy equal to 1,000 watt hours. The kilowatt hour is most commonly known as a billing unit for energy delivered to consumers by electricity utility companies. For example: A heater rated at 1,000 watts (1 kilowatt), operating for one hour uses one kilowatt hour of energy. Also, using a 60 watt light bulb for one hour consumes 0.06 kilowatt hours of electricity. Alternatively using a 60 watt light bulb for one thousand hours consumes 60 kilowatt hours of electricity. Energy is not measured in kilowatts, but in kilowatt hours (kwh). Mixing up the two units is a very common mistake. 1,000 kwh is tonnes of oil equivalent Page 8

9 1ktoe Is one thousand tonnes of oil equivalent. 1ktoe is 11,630,000 kwh Average domestic energy bill On most energy comparison websites there are quotes for the average electricity bill for households around the UK. This is derived from set figures that the energy regulator ofgem (Office of the Gas and Electricity Markets) have provided for electricity suppliers to use. It is basic in its measure and is as follows: Average electricity usage 3,300 kwh for single rate electricity averaged across all regions and average gas usage of 20,500 kwh. Most companies will then quote prices for paying by monthly direct debit, which generally lowers the charges. The current rate for British Gas standard tariff, for dual fuel, works out to be a yearly bill of around 1,300. Formula used to convert gas meter readings to kilowatt hours (kwh) Electricity meters usually show the amount of electricity consumed in kwh. The provider then bills directly for that usage. However, gas meters cannot show the amount of energy consumed, just the amount of gas which has passed through. This is measured in hundreds of cubic feet, or cubic meters if a new metric meter has been installed. For billing purposes this has to be converted to kwh by a formula. A key element of this formula is the calorific value of the gas. This is a number relating to the amount of heat obtained if a certain amount of the gas is burnt. This number can change daily, but generally has a value between 37 and 44. Any regional variations will only make a small difference to a gas bill. The formula used to convert gas meter readings to kwh is generally to take the units used as recorded by the meter and: Multiply by the metric conversion factor 2.83 (If there is a newer metric meter measuring gas in cubic metres you do not need to do this) Multiply by the volume conversion factor Multiply by the calorific value which is currently 39.4 in SE region Divide by the conversion factor 3.6 to get the number of kilowatt hours (kwh). The data The data analysed in this document are based on the aggregation of Meter Point Administration Number (MPAN) readings throughout Great Britain obtained as part of DECC s annual meter point electricity data collection exercise. Across Great Britain, 37 per cent of electricity is estimated to be consumed in the domestic sector, and 63 per cent by the non-domestic sector (compared with 92 per cent of meters in the domestic sector and 8 per cent in the nondomestic sector). However, the split varies across the regions of Great Britain. Domestic consumption accounted for 32 per cent of total electricity consumption in Greater London and 43 per cent in the South West. Page 9

10 Approximately 10 per cent of households in Great Britain are not connected to the gas grid; however the proportions vary across each region. The South West and Scotland had the highest proportion of properties without a gas meter (20 per cent and 18 per cent respectively). In the North East and North West only around four per cent of households are not connected to the gas network. There are no hard and fast conventions as to why some areas use more or less energy than other areas. A number of factors may be at play when it comes to energy use. The size of the property, amount of insulation (walls, roof and windows), income available, employment opportunities, old or new property types, household size, household appliances, type of household, town centre or rural location, geographical location (eg hillside or coastal etc). Further research investigations would be required to establish conclusive reasons for differing energy use. Historically, local authority level statistics have been published by a domestic/non-domestic split. A further breakdown of the domestic sector has now been published providing information by type of domestic meter (standard and Economy 7). The DECC have had feedback that it would be helpful to include the median as well as mean in the published statistics. The DECC have included the median in their published data from The mean is a useful indicator of changes in consumption behaviour over time, however it does not represent the typical consumption or take into account the spread of the data. Energy use at local authority level could vary and fluctuate depending on the type, size and demand of various goods and services. Larger companies may install their own energy schemes or shut down uneconomic manufacturing plants, all of which will affect the amount of energy used from one year to the next. Further information or data at small area level please contact the DECC or KCC Business Intelligence research@kent.gov.uk Use of the Data This bulletin is one of a series on different topics. The data are used for a variety of purposes; generally as evidence and intelligence to monitor and support Kent County Councils (KCC) business performance. The information is also used to support KCC projects, policies and initiatives such as in the formulation of policy, monitoring resources, answering questions, queries and benchmarking against other authorities. The various bulletins are used by and distributed to Kent Local Authority planning policy teams, KCC household population forecasting, KCC district profiles dashboard, KCC Education department, KCC Locate in Kent, the Kent Housing Group (KHG) and the Kent Developers Group (KDG).
