The companies Proquinal – a member of the Spradling Group – and Swissol, accompanied by government authorities, inaugurated the largest and most innovative project in storage of alternative energy in Costa Rica, which will reduce the pressure on public electricity generation and also contribute to the strategy of carbon neutrality for the country.
[PDF Version]Both renewable scenarios will result in a high proportion of variable power generation (PV and wind): 33%–31% by 2030 and 54%–66% by 2050. Such a varied mix of renewables will make Costa Rica's energy system more resilient, eficient and afordable.
To reach this goal, Costa Rica will make changes and modifications to mobility and transport (public as well as private), optimize energy management, promote sustainable construction and industry, and improve recycling and waste disposal.
The largest part of Costa Rica's industrial activity takes place in the greater metropolitan region around San José. It is also the most densely populated area in the country. Therefore, urban and spatial planning play an important role in Costa Rica's energy system.
In a similar manner it is important to foster cooperation between urban and rural local governments in Costa Rica and to increase the role of regional planning in spatial and energy planning. Similar to partnering with institutions, a collaboration mechanism for sharing energy between regions could be implemented.
The Costa Rican government has recognised the importance of this issue and First Lady Claudia Dobles, an architect and urban planner, has spearheaded eforts to develop sustainable urban transportation models. Rican cities. With increasing shares of variable renewable energies, however, smart technologies to balance supply and demand are necessary.
With a 98% share of renewables in its electricity matrix and solid achievements to prevent deforestation – around 25% of the country's land area is in protected National Parks and other protected areas – Costa Rica is at the forefront on issues related to environmental sustainability, climate action and driving the renewable energy transition.
