BOA VISTA, Brazil, Feb 06 (IPS) – Roraima, the northernmost state of Brazil, on the border with Guyana and Venezuela, is present process an vitality transition that factors to the dilemmas and attainable options for a protected and sustainable provide of electrical energy within the Amazon rainforest.
As the one state exterior the nationwide grid – the Nationwide Interconnected Electrical System (SIN) – it’s depending on diesel and pure gasoline thermoelectric crops, that are costly and polluting sources, that account for 79 % of Roraima’s electrical energy.
The monetary and environmental value is exacerbated by the transportation of fossil fuels by truck from Manaus, the capital of the neighboring state of Amazonas, 780 kilometers from Boa Vista, the capital of Roraima.
However the individuals of Roraima pay one of many lowest costs for electrical energy in Brazil, because of a subsidy paid by customers in the remainder of the nation.
These subsidies will value about 2.3 billion {dollars} in 2023, benefiting three million individuals on this nation of 214 million individuals, in accordance with the Nationwide Electrical Vitality Company regulator.
A fifth of the entire goes to Roraima, which from 2001 to 2019 obtained electrical energy imported from Venezuela. This meant the state wanted much less subsidies whereas it loved a level of vitality safety, undermined in recent times by the deterioration of the provider, the Guri hydroelectric plant, which stopped offering the state with vitality two years earlier than the tip of the contract.
Fortuitously, Roraima has pure gasoline from deposits within the Amazon, extracted in Silves, 200 kilometers from Manaus, to provide the Jaguatirica II thermoelectric energy plant, inaugurated in February 2022, with a capability of 141 megawatts, two thirds of the state’s demand.
Roraima thus lowered its dependence on diesel, which is extra expensive and extra polluting.
However what a number of native initiatives are in search of is to interchange fossil fuels with clear sources, resembling photo voltaic, wind and biomass.
That is the trail to sustainable vitality safety, says Ciro Campos, one of many heads of the Roraima Renewable Vitality Discussion board, as a consultant of the Socio-Environmental Institute (ISA), a pro-indigenous and environmental non-governmental group.
The town authorities in Boa Vista, the state capital, dwelling to 2 thirds of the inhabitants of Roraima, has made progress in direction of that objective. Photo voltaic panels cowl the roofs of the town authorities constructing, municipal markets and a bus terminal, and type roofs over the parking a number of the municipal theater and the Secretariat of Public Providers and the Surroundings.
As well as, a plant with 15,000 photo voltaic panels with the capability to generate 5,000 kilowatts, the restrict for so-called distributed era in Brazil, was constructed on the outskirts of the town.
In whole there are seven crops with a capability to generate 6,700 kilowatts, along with 74 bus stops outfitted with photo voltaic panels, a few of which have been broken by theft, lamented Thiago Amorim, the secretary of Public Providers and the Surroundings.
Along with the environmental goal, photo voltaic vitality permits the municipality to avoid wasting the equal of 960,000 {dollars} a 12 months, funds which can be used for social spending. Boa Vista describes itself as “the capital of early childhood” and has received nationwide and worldwide recognition for its applications for kids.
The Renewable Energies Discussion board and the Roraima Indigenous Council (CIR), which promote clear sources, say the intention is to cut back the consumption of diesel, a fossil gas transported from afar whose provide is unstable, and to keep away from the development of the Bem Querer hydroelectric plant.
The challenge, of which there are nonetheless no detailed research, would dam the Branco River, Roraima’s largest water supply, to type a 519-square-kilometer reservoir that may even flood a part of Boa Vista. It could have an effect on 9 indigenous territories immediately and others not directly, mentioned Edinho Macuxi, basic coordinator of the CIR.
Bem Querer would have an put in capability of 650 megawatts, thrice Roraima’s whole demand. It has woke up curiosity as a result of it could additionally provide Manaus, a metropolis of two.2 million inhabitants that lacks vitality safety, and will produce extra electrical energy simply because the era of different hydroelectric crops within the Amazon area is declining.
Nearly all of Roraima is within the northern hemisphere, and the rainiest season runs from April to September, when water ranges run low in the remainder of the Amazon area. The state’s hydroelectricity would due to this fact be complementary to all the Brazilian portion of the rainforest.
That’s the reason Bem Querer is a challenge inextricably linked to the development of the transmission line between Manaus and Boa Vista, already prepared to start out, which might combine Roraima with the nationwide grid, enabling it to import or export electrical energy.
“We are able to join, however we reject dependency, we would like a protected and autonomous vitality mannequin. We could have ten years to search out economically and politically viable options,” mentioned Ciro Campos.
