  • Annual Report 2024: Portugal
    Publication . Couto, António; Costa, Paula Silva; Simões, Teresa; Estanqueiro, Ana
    ABSTRACT: In 2024, the new wind power capacity installed amounted to 64 MW. This capacity results from overcapacity procedures and expansions at existing sites, with only one new wind park being installed. A new version of the NECP 2030 was released, with wind power continuing to play an important role in decarbonization of the power system, setting targets of 10.4 GW for onshore wind and 2.0 GW for offshore wind. For the offshore case, these values align with the work achieved by the ministerial working group created by the Portuguese government to accelerate the offshore wind market. The objective of this group is to establish the necessary conditions for the allocation and installation of 2 GW by 2030 through capacity auctions. The main R&D work in 2024 was focused on training activities in wind energy digitalisation (project TWEED) and create intelligent systems supporting autonomous wind power plant operations (project INTELLIWIND) as well as in developing new larger segmented wind blades to improve performance and environmental sustainability of the materials (project RiSEnergy).

  • New electricity markets: The challenges of variable renewable energy
    Publication . Estanqueiro, Ana; Couto, António
    ABSTRACT: The development and large-scale dissemination of the new and variable renewable technologies took place from 1990 onwards in most developed countries, in a process led by Europe. To promote the renewable sector development financial incentives, both for investment and for the payment of renewable energy, were always present. These incentives usually consisted of guaranteed feed-in tariffs that ensured a return of the investments made in this new business—thus minimizing the financial risks and building a more attractive business for private companies in the renewables sector. That approach was the main basis that essentially supported the remarkable growth of the renewable sector in Europe in the past 30 years. Nowadays, the renewable energy sector is already mature in most aspects. The cost of generating electricity from wind or solar (photovoltaic) resources is competitive with conventional gas or coal-based technologies. However, some challenges still exist in the transition of the electrical power sector to a desirable carbon-free, near 100% renewable-based sector—and one of those main challenges is the negotiation of the electricity generated by these novel technologies, due to the time and spatial variability of the primary resources as well as their poor predictability and dispatchability of the power generated. This chapter addresses those challenges as well as the approaches available to overcome them within competitive electricity markets.
