Cost-effective incentives for end-use measures in a Swedish municipality

• If actors on the electricity market cooperate when end-use measures are introduced the energy-system, cost will be reduced considerably. The marginal cost for electricity for the energy system of the actors will show cost effective incentives for introducing end-use measures. We present a system analysis for cooperation between distributors and customers. We also present results from a project where an existing distributor and eleven existing customers within a municipal energy system have been analysed. The customers are various industries, a hospital, an ice hockey arena, a harbour, a water-works, a warehouse, and a radio tower. The results show that the customers have in different end-use measures a power reduction capacity of maximum 8642 kW. With electricity costs of 1994 this corresponds to a reduction in the energy system cost of 2,852,000 SEK for one year. The results also show that for the distributor`s load curve of 1994, the full power reduction capacity can not be used since the peak loads of the five winter months are not so large and distinct. In that case the energy system cost can be reduced by 1,909,000 SEK, which is 67% of the maximum cost reduction. The end-use measures that are cost effective in this municipal energy system are load management and electricity generation in reserve power plants. We have also studied the profitability for introducing bivalent heating systems based on oil and electricity for heat loads that originally are based on oil. However, with existing electricity and oil costs there are no incentives for increasing the electricity use during non-peak load periods with bivalent heating systems.
