HOT|COOL NO.1/2021 - "Fuel, Flexibility & Green Transition"

Description of projects managed, and value generated Accordingly, in 2014 an intense phase was launched for the construction of district heating systems, with specific projects closely adapted to the particularities of each different area. The first system was installed in Soldeu (a village with a ski resort at an altitude of 1,600 metres, used as the venue for World Cup competitions). The energy source for this district heating system, which supplies the ski resort as well as homes and hotels, is liquefied natural gas, used to generate 13 GWh/ year of thermal energy. The facility is also equipped with a cogeneration engine which produces 6 GWh/year of electricity in the winter months. This district heating system made it possible to replace individual oil heaters at existing facilities and avoided the need to install electric heating in new buildings. A second, very different system was built to provide heating in the urban centre of the country’s capital, Andorra la Vella. In this case, the energy comes from a waste recovery facility that supplies 30 GWh/year of heating energy to the system for residential and service buildings, preventing the emission of 6,700 tonnes of CO 2 . The steam generated by the incineration of waste is also used to produce 20 GWh/year of electricity, distributed over the 12 months of the year. New buildings in the area will no longer use electric heating. Similarly, a new neighbourhood in Escaldes-Engordany will also be supplied by a district heating system powered by centralised heat pumps. Managing the network’s inertia and temperature, the aim is to avoid the production of heat in the grid during peak demand periods. Finally, work on a fourth project is about to begin. Pas de la Casa is a ski resort located at an altitude of 2,000 metres. The aim is to replace the energy provided by individual boilers through the installation of a district heating system fuelled mainly by biomass. The electricity required by these projects will be provided by a high-altitude wind farm currently at the study stage, and which will produce 40 GWh/year.

Future vision In order to manage the energy transition and achieve a CO 2 - free model, FEDA, Andorra’s electricity system operator, has chosen the path of global energy management and transformation into a multi-service, multi-energy company. The systemic vision adopted enables the operator to optimise energy management and efficiency. Throughout its activity, moreover, FEDA is driven by a local vision, closely adapted to the needs of the territory and its customers.

ABOUT FEDA

FEDA is the public corporation that manages the power grid in Andorra, producing nearly all the country's electricity and importing the rest from neighboring countries. FEDA is the driving force behind the energy transition to a more sustainable and environmentally-friendly model. After the crisis of 2007-2008 and the volatility that this generated in prices in energy markets, FEDA began integral management of energy risk in Andorra by diversifying production sources, restructuring demand, and ensuring flexibility. As part of these measures, FEDA became firmly committed to district heating, which is now a key element in transforming the energy model and Andorra's decarbonization. The company's subsidiary, FEDA Ecoterm, established to develop DH, currently manages four projects.
