58 MW electricity storage brings grid stability and cheaper energy

An agreement was signed in Windhoek this week to fund Namibia’s first industrial-scale battery power store, which will ultimately improve the stability of the national grid, replace imports, dismiss Van Eck and reduce the cost. electricity.

The bilateral agreement between the German and Namibian governments released € 20 million in funding from the Kreditanstallt fuer Wiederaufbau (KfW) to NamPower, the utility responsible for execution and implementation.

NamPower chief executive Kahenge Haulofu said the project will help the utility meet the target of 80% self-generation by 2023 as part of the national energy policy. It will also help achieve the target of 70% renewable energy by 2030.

In a joint statement released on Friday, December 17, 2021, funding and implementing partners said the money was intended for Namibia’s very first Battery Energy Storage System (BESS).

The funding covers the construction of a 58 MW / 72MWh BESS plant at the Omburu substation near Omaruru. About a fifth of the total cost of the project will be covered by NamPower. Their contribution will be used for the construction of the transmission interconnection, as well as for various tariffs and taxes not included in the financing under the bilateral agreement.

“Once commissioned, NamPower will be able to use a combination of various applications that have been identified for the Omburu BESS, namely peak shift, energy arbitrage, emergency power supply, ramp speed control and reactive power control, ”the partners said.

This battery will be the largest such system in southern Africa to date.

Having a battery storage facility will allow NamPower to actively participate in electricity exchanges between the 12 members of the Southern African Power Pool.

Since it will also improve grid stability, it opens the door to foreign investment in more renewable energy projects.
