FAQS about Brazilian power grid company s energy storage requirements

Why is electricity storage important in Brazil?

Electricity storage in Brazil The rise of renewable intermittent sources and the fall of stored energy in hydropower dams raises the risks associated to power security, but it can also pave the way for new technologies such as electricity storage .

Will Brazil's energy auction improve power grid reliability?

Interest in the auction has been expressed by power companies such as Portugal’s EDP and Brazil’s ISA Energia. The auction will enhance Brazil’s power grid reliability by integrating energy storage solutions for electricity generated from renewable sources such as wind and solar. US Tariffs are shifting - will you react or anticipate?

How can storage technologies support renewable generation in Brazil?

Connecting storage technologies to renewable sources of electricity can support short-term generation stability and engagement in services that a stand-alone renewable generation asset cannot, but the current regulatory framework in Brazil needs to advance for this to become a viable option.

What percentage of Brazil's electricity is supplied by the NIS grid?

Only 1%–7% of all electricity demand in Brazil is not currently supplied under its National Interconnected System (NIS Grid), a large-scale hydrothermal transmission system, predominantly made of hydropower plants . The basic lines of the NIS Grid are comprised of 230 and 750 kV tensions.

Is Brazil bringing storage into the energy transition?

Brazil is taking its first steps toward its ambitions of bringing storage into the energy transition of its electricity sector.

What are electricity storage technologies in Brazil?

In general, electricity storage technologies are in their initial stage in Brazil. In 2016, the national regulatory body for electricity (ANEEL) selected twenty-three R&D projects that span a diverse range of technologies that includes batteries.

Honduras Energy Storage Power Company

In November 2024, Honduras made waves with its 75MW/300MWh battery storage tender – the energy equivalent of building a 4-hour power bank for 75,000 Honduran households [1]. Fast forward to March 2025, and China's Windey (运达股份) teamed up with Spain's Equinsa to clinch the $50.2 million contract [2]. [pdf]

Namibia Energy Storage Lithium Battery Company

NamPower, Namibia's state-owned power utility, has signed a contract with a Chinese joint venture to build the first utility-scale battery energy storage system (BESS) in the country and the Southern African region. [pdf]

FAQS about Namibia Energy Storage Lithium Battery Company

Who owns the Namibe Lithium Project?

Tyranna Resources, an Australian-based mineral exploration company, will acquire an 80% interest in the Namibe Lithium Project. The Acquisition is expected to be finalized by July 2022, positioning the company as the majority owner of the project.

How much electricity does Namibia import?

Currently Namibia imports up to 70% of its electricity from neighbouring countries. This electricity is predominately generated with coal.

How will Namibia improve energy supply stability by 2030?

By 2030 the Namibian government plans to increase the share of renewable energies (RE) in its electricity generation from around 30% to 70%. With a growing share of RE the need for measures to maintain and improve energy supply stability is also growing.

Could surplus electricity be stored in the Bess?

Surplus electricity from RE generation as well as cheaper electricity imports from the Southern African Power Pool (SAPP) can be stored in the BESS. The stored energy could supply customers during peak times and would offset fossil energy from the aging local Van Eck coal power plant.

Can a battery storage system support the integration of re?

A battery storage system such as the KfW funded 58MW / 75 MWh Omburu BESS Project can fulfil a multitude of tasks related to the challenges of the integration of RE and is ideally suited to support the sustainable development of the Namibian electricity sector.

Why is Namibia a pioneering project?

As the project is the first of its kind in Namibia, it fulfils a pioneering function - it is expected that subsequent projects in the same field will benefit substantially from the experience gained from within this project. Currently Namibia imports up to 70% of its electricity from neighbouring countries.
