Energy battery costs

The country is betting on energy storage through batteries, but this alternative could have a huge cost.

The storage of energy through batteries is positioned as an alternative to guarantee continuity in the energy services for the Caribbean coast region, Portafolio reported.

However, this can turn out to be an expensive and inefficient option.

The Ministry of Mines and Energy (MinEnergia) is working on the Battery Energy Storage System (SAEB), and this project would represent investments of US$40M, a high value compared to other alternatives that could provide the same task at lower cost.

In addition, the National Operation Council (CNO) warned that the SAEB could lose its relevance within the National Interconnected System (SIN) in four years.

The CNO said that the battery complex has a high investment and is inappropriate. The entity explained that there are more economical and efficient systems to improve the provision of electric power service in the Caribbean region.

“Devices with power electronics that drive lines to withstand more current load have the same technical benefits as SAEB. These elements have the advantage of being installed quickly, relocating to other SIN subareas, once conventional network expansions are in service, and they have the lowest implementation cost,” CNO said.

Representatives of MinEnergia said that the storage project with batteries of 50MW of installed capacity is to supply electricity in a contingency case.

Bottom-Line: This initiative has had several problems for its development, as the Mining-Energy Planning Unit (UPME) announced a change in the auction schedule for the Battery Storage System (SAEB) in Colombia.

It seems like authorities are already rethinking this project…
