6 Frequently Asked Questions about “Substation Energy Storage Project”
What is a power substation?
Electricity substations play a role in both stepping up the voltage of electricity for distribution on grid and in transforming it into lower voltages for delivery to end consumers. The Kawerau substation is one of 13 substations within the Bay of Plenty (BOP) region and is interconnected to the grid through both the 110 kV and 220 kV networks .
What is Asia's largest battery energy storage system for grid stabilization?
As Asia's largest battery energy storage system for grid stabilization, it has a power output of 978 MW and a storage capacity of 889 MWh. The completion ceremony took place on September 27 at the 154 kV Bubuk Substation.
How to build a substation?
Create the substation project with scheduled milestones and in-service date. Begin engineering & design of substation drawing package and deliverables. Perform a final design review meeting along with a pre-construction meeting. Finally construct, test, and implement new substation.
How many KEPCO substations are there?
It was carried out in phases and across KEPCO's six substations (Yeongju, Hamyang, Yesan, Yeongcheon, Shinnamwon, and Bubuk). The final and the biggest portion of the project – the 336 MW battery energy storage system at the Bubuk substation in the Nano Industrial Complex, Miryang-si, Gyeongsangnam-do – was switched on in July.
Will KEPCO build another 300 MW battery energy storage system?
The utility also plans to build another 300 MW battery energy storage system by 2028. Korea Electric Power Corp. (KEPCO) has completed construction of a large battery energy storage project in Miryang, Gyeongsangnam-do Province.
Is Bess a new energy storage technology?
Although other energy storage technologies are well established, BESS is considered as a new evolving technology which many utilities and system owners may not be familiar with. This Technical Brochure will provide a guide to how to implement BESS in a substation, both for existing and new substation projects.
