Identification of potential

ERAMAC – Evaluation of Madeira’s island solar potential

The ERAMAC - Maximizing the Penetration of Renewable Energies and Rational Use of Energy in the islands of Macaronesia project intended to promote and increase the diversification of sustainable energy in Macaronesia preventing the use of energy to become a constraint to the development of the islands. Within this goal several studies were made to assess the Madeira island potential for renewables adoption. One such study was the Evaluation of solar energy potential in the Autonomous Region of Madeira from which it was concluded that this are presents an enormous potential for solar technologies adoption, both thermal and photovoltaic.

Mobilization of potential

City of Obidos

The Óbidos Solar project was initiated by Óbidos Municipality aiming to support its citizen’s access to solar technologies within the national micro-generation framework.

The Municipality conducted a partnership with several private companies who invest in the solar micro-generation system (a 2sqm solar thermal system combined with a maximum 3.68 kWp solar photovoltaic system) installed in private residential houses.

The housing owner invests 1.000 € (plus the costs associated with the system registration in the micro-generation framework) and allows his roof exploration by the company with who he contacts the service during 9 years. As benefit he will receive 25% of the profits for the energy sale to the grid with the feed-in tariff scheme during the 9 years contract, period after which he will start to receive 100% of the electricity sale profits and be the formal owner of the equipment. The house owner also fully benefits from the solar thermal system, reducing the costs incurred with the hot water production. Since the beginning of the project 400 Óbidos inhabitants have presented their interest in joining the programme, and from these 30 have successfully installed micro generation system in a total installed capacity of more then 100kWp.

Town planning

City of Lisbon : Baixa Pombalina Solar Potential

The Baixa Pombalina area is considered the most important historical area of Lisbon. It is listed as heritage and managed by IGESPAR, the entity responsible for the management of the national archaeological and architectural heritage. As a result of this heritage status all the buildings in this area are not required in any way to include solar thermal systems. Despite the historical status of this Central Historic Area, Baixa Pombalina is one of the least inhabited areas of Lisbon as it has been unable to maintain a balance faced with the dominant transformations over the years, and this fact motivated the Municipality to promote a Detailed Urbanization Plan for this area. This Plan is being developed in close collaboration with IGESPAR and it establishes the soil use and refurbishment conditions for the Baixa Pombalina area.

In the context of Baixa Pombalina’s urban refurbishment plan, Lisboa E-Nova, in cooperation with the Municipality and IGESPAR, promotes the development of the Solar Systems Integration Potential in the Lisbon Baixa Pombalina Area. This information is to be integrated in the Baixa Pombalina Urban Plan, in order to promote the integration of solar systems in the process of buildings refurbishment, according to the area’s cultural heritage requirements. This is an innovative study as it promotes solar systems integration in historical classified areas, identifying the solutions to successfully integrate in these buildings, solutions that can be adopted not only in this area but also in other historical listed areas in Portugal.

Policy and legislation

City of Lisbon : Lisbon new framework for urban edification

Lisbon Municipality approved in 2008 the new framework for urban edification, RMUEL. In this framework, the Lisbon Municipality included for the first time a chapter dedicated to energy efficiency and renewable energies integration. Clear guidelines are presented towards the integration of sustainable practices in urban operations, namely regarding buildings location and orientation according to the needs of passive cooling and heating strategies and the promotion of thermal comfort through the optimization of solar gains. Urban operations should also focus on energy efficiency strategies, namely for natural lighting, and renewable energy adoption, especially for electricity and hot water production. To this end, the Municipality will consider to give incentives for the adoption of RES through adequate rates and taxes.
