1 Integration of technical systems in the Gävle region GAS WASTE WATER WATER SUPPLY Utmanin DISTRICT HEATING gar Håkan Jönsson Acting CEO Gävle Energi

2 Gävle and the Gävle region Where are we? Gävle City since: 1446 Gävle region Population: Area (km 2 ): The Gävle Region is a major industrial area in Sweden with paper- and saw mills, steel and metallurgical industries. Gävle is famous for food products like candy, coffee, whiskey and fish products And of course the christmas goat

3 Biofuel-based Combined Heat and Power Renewable heat and electricity Hydropower Seven hydropower plants Wind Power Part-owner Samkraft Vind AB Recycled Energy Heat from industrial processes Gävle Energi Bionär Närvärme Subsidiary small scale district heating District Heating 99,2 % bio-based heat in Gävle District Cooling Sustainable cooling Electrical Grid Smart and reliable electrical grid Renewable Electricity 100 % renewable electricity GavleNet Fiber and broadband Energy Services Optimization of energy use SBI Ekogas Biogas produced from organic waste

4 Ekogas Started in 2010 with the opening of a gas filling station near the bus depot In 2011 the upgrading plant at Duvbacken The market development exceeds the The start up is about to take the next step Gas filling station 1 Sörby Urfjäll Production facilityduvbacken Forsbacka

5 The technical systems today District Heating DISTRICT HEATING Separate systems GWh / year Production unit Distribution network Waste heat from industries i Gävle and Skutskär Limited growth potential within the systems

6 The technical systems today Water and waste water WATER DISTRICT SUPPLY HEATING Separate systems Scarce resource in Gävle Back up water supply needed Waste water plants at maximum capacity Raw water supply Waste water processing plant WASTE WATER

7 The technical systems today Gas for industrial purposes GAS DISTRICT HEATING Mainly LPG Distribution by railway or road transport Industrial gas use

8 Gas as a catalyst for infrastructure development The catlysts A LNG gas terminal in Gävle seemed very likely, both Scangass and Swedegas show great interest. The interest from Swedegas to establish a gas distribution network The participants: Objective: From a holistic perspective evaluate the conditions for and the potential in integrating technical infrastructure in the region The study was conducted by Ramböll

9 The findings District Heating DISTRICT HEATING Increased use of waste energy Improved evironmental impact Production unit Distribution network Connecting distribution networks Increaesed comeptitiveness for the industry Potenatial for more waste energy

10 The findings Water and waste water WATER DISTRICT SUPPLY HEATING Redundant water supply Coordinated waste water treatment Increased biogas production Raw water supply Waste water processing plant New water distribution New waste water distribution WASTE WATER

11 The findings Gas for industrial purposes GAS DISTRICT HEATING The market for industrial use of methane >500 GWh Increased industrial competitiveness Industrial gas use Gas distribution network LNG terminal Biogas production Increased potential for biogas production Less environmental impact

12 The potential is bigger than the sum of the parts A hypothetical scenario The potenials Economy of scale in jointly establish distribution networks Increased use of waste energy Maintaining existing industries competiviness Attracting new businesses Less environmental impact Secured water supply More efficient waste water treatment Biogas production From residues Power to gas? Thermal gasification? The next step? Sandvik as a supplier of residual heat to the district heating system? Cost benfit analysis for a regional integrated district heating system Evaluate the alternatives for locating the infrastructure for distribution of water, sewage, district heating and gas

13 The potential in jointly establishing regional infrastructures for gas, water, sewage in the Gävle region is vast. There is, of course, an economy of scale in the planning and construction of the networks. The true potential, however, lies in: 1. The joint infrastructures potential for improving the regions traditional industries competitiveness 2. The potential for regional growth and attractiveness We will work further with the integration of technical systems with those who have an interest in participating in the development of the Gävle region and beyond
