Half this cost is covered by the differential between the increased (+5%) electricity tariff paid by high-consuming domestic customers and the discounted tariff (-2.5%) paid by low-consuming ones. The remainder is covered by national and EU funds, and by the proceeds of the taxes on electricity consumption and on low energy efficiency lighting.12 Most of these resources are channelled to low-interest loans for investments in energy efficiency measures, “efficiency cheques” and the bonus for renewal of electric appliances (Section 4.2). Launched in 2008, the SGCIE broadens the scope of the 1986 Regulation for Energy Management to include a larger number of installations, thereby increasing potential energy savings. The SGCIE imposes binding energy audits: participating companies are obliged to implement multi-annual energy rationalisation plans to reduce their energy consumption and/or intensity, and to report periodically on their progress.
