A solar stock exchange
A marketing research on ecological charges, realized in 1999 by the City of Lausanne, showed that an important part of the City’s electricity customers were
ready to pay a supplementary charge to obtain electricity produced from renewable instead of fossil or nuclear resources. The research outcomes gave rise to the idea of introducing an innovative financing concept using investments from the private sector to fund new solar power installations: a "solar stock exchange".
The working principle of the solar exchange is simple. On the one hand, there are electricity customers willing to pay a higher price per kWh in case power has been generated from renewable energy sources. On the other hand, there are renewable electricity producers who finance, design and install PV units on private buildings. Lausanne’s Utilities Company (SIL) negotiates agreements with these producers to purchase their entire solar power production.
Lausanne Utilities is situated between customers and power producers.
Internal contracting among city departments
Stuttgart, located in the south west of Germany is the capital of Baden-Württemberg; In 1995 the Energy Management Department introduced the ‘internal contracting (intracting)’ model together with the City Treasury. This financing system takes up the idea of contracting, but operates exclusively with the budgetary funds of the city. Investments are financed by the Environment Department from a special budget item, to which the energy cost savings are later returned. Consequently, such an item can be set up for a limited term. Over time, the budget item is replenished from ongoing savings, so that, after an initial
start-up phase, further funds can be made available for new intracting measures.
