Call for first utility-scale energy storage in Colombia


Colombia’s first utility-scale battery storage system is planned to reinforce the transmission network in the Atlántico department.

The 45MWh system with a minimum delivery duration of one hour is to be connected to Air-E S.A.S. E.S.P’s 110/34.5kV Silencio substation in the country’s north coastal city of Barranquilla.

The project, a first for Colombia and believed also the region, forms part of reinforcement works on the regional transmission network in the department and the deferral of investment in new local generation.

Other elements in the project include installation of a 34.5kV bay in the substation, extension of busbars and the implementation of a control and communications system, as well as other components and design, construction and commissioning works to bring the system into operation.

Approximately 2km of 34.5kV transmission lines also are required.

The call from the government’s Mining and Energy Planning Unit (UPME) requires parties to register their interest and present their offers over the next three months with the investor selection hearing scheduled for April 14, 2021.

The battery storage system is intended to come into operation by June 2023.

A statement from the ministry of energy points out that as batteries are a convergent asset, the incorporation of storage in the expansion of the network opens up a wide spectrum of possibilities in the way that agents participate and the system is operated.

“In this sense, this first call for storage is an important milestone in the transformation of the system in the face of the energy transition.”

The bids will be assessed on the basis of the ‘expected annual income’ (IAE), i.e. the proposed remuneration, for the development and execution of the project.

Air-E, formerly Caribe Sol, is the regional electricity distributor in Atlántico, as well as in the La Guajira and Magdalena departments.
