Planning subtask A3: Socio-economic problem formulation
Local energy planning in Hylkje

Electricity is the main energy carrier in Hylke. This means that a large part of demand for heat, hot water, etc. is covered by electricity and most of appliances owned by the consumers (especially households) are using electricity. In addition, gas (LNG) will also be available in the near future once a new gas processing facility situated close to Hyljke will start production.

System’s boundaries in this case study have been drawn geographically, in order to include the areas where the increase in energy demand has been forecasted. A simplified representation of the region includes: 'the town' and the industrial site outside the town as shown in the figure.


A schematic representation of system boundaries

Gas and electricity are ‘imported’ at system boundary. The electricity import is in terms of quantity of energy imported (with its daily variations) with associated marginal cost (price) at system boundary and emissions. It has been assumed that the electricity import triggers marginal changes in the global CO2 emissions and that the price of electricity at system border does not include taxes (for CO2 or other local emissions). The gas import is taken into consideration only in terms of quantity and price.

The main long term planning objective is to assure a reliable energy supply in the region analysed to all old and new consumers in the region. The decision maker (the local energy company) must also consider the general guidelines provided by the national energy plan and policies
