P.D. LundResidential Energy-Efficient Lighting Programme in Pori Helsinki University of Technology, Finland J. Kataja and V. Leivonniemi Porin Energialaitos, Finland Abstract In this paper, the first utility lighting efficiency programme in Finland is described. The programme was conducted in the city of Pori and 17,000 18-Watt compact fluorescent lamps were given free of charge to residential customers. The delivery of the lamps to the customers took place in less than 2 days. The practical realization was followed by a detailed energy and economic analysis. A comprehensive survey has also been undertaken among the customers to assess the impacts of the programme and to collect practical experiences. It is found that the lamps reduce the peak demand by about 50% of the maximum possible. The effective energy impact fraction of lighting efficiency measures were estimated to be about 60% in the worst case due to the increase of the heating demand when CFLs are used. The utility paid 42FIM (8.4 ECU) for a single CFL and the survey indicated that a customer would be willing to pay 37 FIM (7.4 ECU), respectively. The analysis showed that the Pori project is profitable both to the customers and national economy, but unprofitable to the utility itself. This is mainly because of the loss of revenues resulting from lower electricity sales.
