What tax incentives do renewable energy projects get (Decree 52-2003)?

The Law on Incentives for Renewable Energy Projects (Decree 52-2003) exempts imports of equipment from customs duties (DAI) and VAT (IVA) and exempts projects accredited by the Ministry of Energy and Mines (MEM) from corporate income tax (ISR); it also exempted them from the IEMA,… a tax since abolished. The exact terms of each exemption (pre-investment and construction periods, years of income-tax exemption, article 5) were not confirmed against the text on this pass. Nor was the list of projects accredited by MEM's Directorate General of Energy located.
