Given their ease, flexibility and rapid implementation time (from 9 to 12 months), the development of these systems is accelerated, being used not only in the industrial sector, but also to support the energy supply in residential complexes.

Wednesday, August 10, 2022.- Achieving more demanding goals in terms of generation and penetration of renewable energies is one of the greatest global objectives. In fact, according to the latest report published by BloombergNEF, it is expected that, by 2050, almost half of the energy generated will come from renewable sources, while hydroelectricity, nuclear energy and other clean sources will inject another 21%.

For its part, the study projects that fossil fuels will fall from the current 37% to only 12% being used by this date.

Undoubtedly, these metrics are very hopeful for reducing the current problem of global warming, but, to meet them, it is necessary to continue developing and massifying the use of complementary systems that allow the permanent availability of renewable energy when the schedules of each source (wind or solar) are not able to meet the required kWh, as is the case with storage batteries.

Given its ease, flexibility and speed in implementation time (from 9 to 12 months), the development of these systems (which are no larger than the size of a container) is quite accelerated, being used today not only in the industrial sector, but which also to support the energy supply in residential complexes.

However, “there is still a long way to go given that, currently, these batteries do not exceed 4 hours of energy availability, so we continue to work incessantly to make these systems more and more robust and make them more competitive”, highlights Raúl Tejeda, Operations Manager of the Engineering area of ​​Black & Veatch.

Another factor that has been complicit in the accelerated growth and implementation of these storage mechanisms is the drop in costs that the industry has shown.

“In detail, during 2010, 1 kWh of clean energy cost around 1,500/kWh. Today this same KwH has an approximate cost of 150/kWh, and it is expected that, by 2030, it will have an approximate value of 75/kWh. This significant decrease today is making viable many projects that were previously unthinkable due to the economic factor,” adds the executive.

scalable technology

Likewise, another of the benefits of storage batteries is that they are scalable, that is, if more electricity generation capacity is required, several joints can be installed and cover the required demand.

The engineering implemented to build these systems requires advanced knowledge that few providers have managed to develop.

Black & Veatch has participated in more than 49 GW in photovoltaic projects worldwide, as well as in more than 56 GW in wind generation, performing various functions: from independent engineering to support the financing of projects, to contracting in turnkey (EPC).

“Finally, the question is whether these energy storage systems will replace conventional renewable energy generation, and the answer is no, but it is one of the most powerful pillars that today supports, makes more flexible and is allowing the mass use of clean energy. in different productive and residential sectors thanks to the expansion of energy availability at required peak times”, adds Tejeda.
