The "Ley General de Electricidad" has been in Congress for many years (5-6) and it favors Solar Energy. You night want to talk to its Senators-authors:
Dar?o G?mez Mart?nez (dario.gomez@senado.gov.do)
Jos? Gonz?lez Espinosa (gonzalez.e-ptd@senado.gov.do)
Antonio Rosario (antonio.rosario@senado.gov.do)
Regarding the new ITBIS, the new Law (Article 344 - section 4) states that electricity services as well as water services are exempt from paying the ITBIS Tax.
