Interfaces between supplier and consumer is normally an issue that we do not discuss that often, even though this is the main issue for all district energy companies in their everyday life. The main reason is, that across the world the interface between producer, distributor and consumer of district energy is different. Some places the district energy company controls the secondary side and some places they don’t. In some countries there is no split between production and distribution and others, like in Denmark, it is clearly separated. However, as the demand keeps rising for increased energy efficiency in the district energy market and keeps prices low, the interaction with the end consumer is inevitable. At the end of the day, everything starts at the consumer. We need to understand our consumer’s demands and installations to deliver sufficient heating or cooling. But this is not enough, as consumption patterns and simple awareness of how heating or cooling is consumed will affect the consumption of the individual as well as the overall economy and efficiency of the district energy company. Besides the economic benefits for consumer and the district energy company, communication between distributor and consumer brings along environmental benefits by lower overall consumption and energy use at distribution level as well as increases the service level felt from the consumer. It is not every day that we as consumers are encouraged to lower our bills, but this is actually the fact across many district energy networks, and especially in Frederiksberg, Denmark as you will learn inside this issue of HOT|COOL.

The clear interface between distributor and customers is slowly being eroded as the district energy companies educate its customers and the industry delivers ever more sophisticated products to themarket that embrace the new possibilities for communicating. A new visualization platform in the form of phones, tablets and PC’s have emerged and makes communication and education of consumers easier and much more interactive. But, how far can you go and how much would you like to involve the customer? The threat is that extensive information and choices will decrease the involvement of the customer as heating is not on top of their agenda. As you will read in this issue, this is on the minds of both the district energy companies and the industry that supplies the solutions that can measure and visualize the customer’s consumption and help the companies’ communication with its customers. At the end of the day a lower - and better consumption of heating and cooling that will increase the difference between supply and return temperature, will result in a more competitive district energy market where the consumer can see the benefit of its behavior on prices and the environment. We are constantly looking at increasing the efficiency of the production and distribution, now the time has come to involve the consumers to go the extra mile to make district energy even more attractive to consumers and politicians alike. Increasing the awareness of what district energy is really about, by eroding the interface, could maybe be the one thing that makes district energy more than “just” pipes in the ground.

CASE

In the years ahead, district heating will generally play an increasingly major role in Europe, as no less than 40% of the energy consumption is used for heating homes. Using district heating as an energy source permits significant reductions in the carbon account, allowing us to conserve and protect our environment now, tomorrow and in the future.

In Kohtla, Estonia, isoplus Denmark has supplied pipes for establishing a new district heating supply between the towns of Järve, Ahtme and Sompa. By the end of 2012, a total of 34 km of pre-insulated pipes will connect these three picturesque towns with district heating. All towns used to have district heating, but the existing heating works are due to be shut down. Instead, the region’s refinery, owned by VKG Soojus AS, will supply the towns with environmentally friendly surplus heat. This is one of the few places in the world where they refine ‘shale oil’, extracted by pyrolysis of sedimentary rock containing kerogen, which can be transformed into petroleum-like fluids.

KNOW-HOW RELATING TO PRE-INSULATED DISTRICT HEATING PIPES

In Denmark, approximately 40% of the district heating production is based on non-fossil fuels, thus being CO2 neutral. This means that we are well positioned to help other countries meet their targets for reducing their CO2 emissions. VKG Soojus AS had no previous experience of installing transmission pipelines of the order of magnitude in question, and isoplus has therefore been involved as a close partner throughout the entire process.

THE NEW DISTRICT HEATING NETWORK S EASY ON THE ENVIRONMENT

The environment in Kohtla will in future be spared a good deal of CO2 emissions, due to utilisation of the surplus heat from the refinery, so that the need to use other fuels will be reduced, including those of fossil origin, which would otherwise have been used to fuel the district heating system.

EXPORTING THE RIGHT SUPPLY OF HEAT AND KNOWLEDGE

ALARM SYSTEM Innovative product development to meet the ever-changing requirements of the market and use of the latest technology are important aspects. This is why the district heating system in Estonia was provided with the newly developed isoAlarm 4500. The alarm system will in future alert system operators via text messaging and e-mail to any moisture ingress in the insulating polyurethane foam, allowing VKG Soojus AS to repair any fault before damage to the pipe system is sustained. This ensures safe and stable operation of the installation. TRAINING AND SUPPORT FROM ISOPLUS isoplus operates on the basis of a “total quality” concept, where we do our utmost to provide our customer base with a quality experience for the full duration of our partnership, right from the very first contract until the pipes are in the ground and the installation is up and running. In Estonia, the partnership has been all the closer in that the Estonians had no prior experience of installing a transmission pipeline with the dimensions in question. At isoplus we have therefore also taken charge of the necessary training of supervisors and personnel from VKG Soojus AS, as well as instructing the sub-contractors’ staffs in how to assemble and install the joints and use a foaming machine. To see the project through to its full and proper conclusion, isoplus also dealt with practical problems, such as, e.g., provision of generators and foaming machines.

Incidentally, it was the sizeable production capacity, quality and technical capability that led to VKG Soojus AS selecting isoplus Denmark as supplier to begin with. The delivery to VKG Soojus AS does not just involve supply of district heating pipes, but electrical fusion joints as well. All mantle joins are executed using electrical fusion, a technology which ensures that the system is provided with the safest joint on the market – and with full documentation covering the entire assembly process. To ensure that everything is executed in accordance with current standards, isoplus has taken charge of all static calculations for the pipe system, and we have also produced the requisite project drawings. In addition, the contract also provides for a monitoring system, electrical pre-stressing, and the overall design of the pipe system. All project drawings relating to the procedures for electrical pre-heating have also been executed by isoplus. STATIC COMPENSATION ON 30 SECTIONS Pipe-laying in the 17 km long channel using pipes of DN 500 dimension imposed specific requirements of its own. Due to the large pipe dimensions and the installation’s high maximum temperature of 1400 o C the system had to be subjected to electrical thermal pre-stressing. Where pre- heating of this type is performed, the system’s axial stress can easily be reduced to around half of that of a system which is laid cold.

The thorough training we delivered ensured that the project ran smoothly, focusing very much on safe and correct execution at every stage. DELIVERY AT THE RIGHT TIME AND PLACE It was not just training and support for the district heating installations in Estonia that meant special requirements for isoplus. The logistics also require extensive planning, coordination and cooperation with VKG Soojus AS, given that, at peak times, 16 trucks a week have to deliver consignments over the course of five working days per week – a task which was solved via close dialogue with VKG Soojus. Only thanks to this close cooperation was it possible to deliver the entire system in a record-breaking six months.

• Leak Surveillance is an intelligent feature which informs the utility in case of leakage. An additional flow sensor (V2) is mounted in the outlet pipe which allows the meter to compare mass in inlet with mass in outlet. If the comparison shows an imbalance an alert is sent via the AMR-system. • By adding an adding an extra temperature sensor to the Leak Surveillance system it is possible to monitor the meter accuracy and generate reports on errors and deviances. The feature is known as Automatic Meter Fleet Surveillance. • Automatic Leak Protection is also based on the Leak Surveillance system: with a serial >Page 1 Page 2 Page 3 Page 4 Page 5 Page 6 Page 7 Page 8 Page 9 Page 10 Page 11 Page 12 Page 13 Page 14 Page 15 Page 16 Page 17 Page 18 Page 19 Page 20 Page 21 Page 22 Page 23 Page 24 Page 25 Page 26 Page 27 Page 28 Page 29 Page 30 Page 31 Page 32
