1 DETAILED HEATING DATA WHAT CAN IT BE USED FOR? NINA DETLEFSEN

2 DANISH DISTRICT HEATING ASSOCIATION Lobbying organisation towards Government, parliament Other organisations Internationally Organizing co-operation between members Best practise Know-how groups Communication Service to members Promoting district heating Projects and analyses 2

3 MEMBERSHIP BASE 394 members representing 99% of national DH-sale From 50 consumers in villages 1 GWh/y To consumers in cities GWh/y 49 municipally owned utilities (app. ½ of DH sales) 329 private cooperatives (other ½ of DH sales ) 3 transmission companies 13 associated members Members supply 64% of Danish citizens with heat for space heating and hot tab water 3

4 Why district heating and cooling? Only when socioeconomic value is positive

5 LOTS OF DATA EXISTS Public available in Denmark DataHUB (electricity data) BBR ( Building and housing register ) FIE-data (Energy information on BBR level) SCOP Other heating consumption data Control your heat pump - project Hourly consumption data in district heating networks

6 CHALLENGES Open data access vs data protection Protection of personal data? Aggregated vs detailed When is details nice to know or need to know Collecting more data is costly Increased value should exceed costs

7 DEMONSTRATION AARHUS Example 1: Demonstration ambition Test technical challenges and business models for combining DH and local heat and electricity production based on RE Greater interaction between electricity and heat Site Social housing building in existing DH area Activities Energy efficient building renovation Smart metering Low temperature district heating Heat-up of local RE system based on waste water heat recovery heat pump and PVT Second life batteries for energy storage Efficient flat stations Creating system value from metering data Central and decentralised supply solutions Buildings, appliances, transport Dynamic integration through technical components, services and pricing signals

8 DEMONSTRATION AARHUS Example 2: Demonstration ambition Site Creating system value from building renovation and metering data Existing DH area with single family houses Activities Testing approaches for energy efficient building renovation Smart metering Gradual transition to low temperature district heating incl. adjustment of existing network Optimization of DH distribution and demand Central and decentralised supply solutions Buildings, appliances, transport Dynamic integration through technical components, services and pricing signals

9 A FEW OUTCOMES OF READY Increased knowledge of the energy flow on both building level and apartment level Study apartment buildings possibility to provide flexibility Testing integration of different smart energy solutions within one building Buildings, appliances, transport Central and decentralised supply solutions Dynamic integration through technical components, services and pricing signals

10 IMPROVED KNOWLEDGE ON ENERGY CONSUMPTION IN BUILDINGS Data from FIE-database (Ministry of Housing, Urban and Rural Affairs) Yearly data for heat consumption for District heating Oil consumption Gas consumption Purpose of analysing this data is to develop tools to be used by members of the Danish District Heating Association Challenges with data: Missing data for electricity consumption for heating and individual biomass heating solutions Yearly resolution Periodicity

11 COMPARISON FIE AND BBR Single family houses in Denmark BBR District Heating Oil Natural Gas Other

12 HEAT CONSUMPTION FOR SINGLE FAMILY HOUSES Heat consumption pr. m 2 for single family houses m 2 kwh/m Pre DH under 2150 DH over 2150 Heating oil Natural gas Building Regulation

13 MUNICIPALITY OF SKANDERBORG OIL SUPPLY IN 2012 REGISTERED OIL IN BBR

14 EXPANDING DH IN THE MUNICIPALITY OF SKANDERBORG OIL SUPPLY IN 2012 REGISTERED OIL IN BBR

15 OIL CONSUMPTION KWH/M2

16 WHY DO WE NEED DATA? Green development Fossil free electricity and heating sector by 2035 Fossil free energy system 2050 leads to discussing Energy savings of all kinds also heating Invest in energy savings Zero-energy houses Efficient production of heating etc. Mainly focus has been on consumption (households) and production/transmission (DH company)

17 DATA FROM A DH COMPANY POINT OF VIEW Detailed knowledge on yearly consumption on building level interesting to decide if district heating should be expanded or not DH Users/costumers has traditionally not had so much focus on the district heating unit installed. Provide extra service District heating companies use detailed data to optimize production And minimize loss in the transmission system Users (some) has focused on energy savings such as isolating, reduce water and electricity consumption advices can be given based on detailed data New products becomes available due to smart metering: Warnings if something happens Saving if peaks can be avoided Postponed investments if allowed to be flexible
