■Background

In recent years, against the backdrop of the expanding adoption of renewable energy and the growth of the electricity supply-demand balancing market, interest in grid-connected energy storage facilities has been rapidly increasing.

On the other hand, for high-voltage grid-connected battery storage facilities, the barriers to new development are rising year by year due to soaring construction fees charged by electric utilities and the increasing difficulty of grid connection.

Amid these circumstances, many new operators are entering the low-voltage grid-connected energy storage facility market—which is relatively easier to enter—leading to intensifying market competition. Consequently, it has become essential not only to construct energy storage facilities but also to establish business models that balance profitability with operational efficiency.

■Service Overview

WQ provides a one-stop solution for low-voltage grid energy storage facility projects by combining the development and power generation application expertise we have cultivated in the renewable energy sector with advanced aggregation capabilities through partnerships with domestic aggregators.

Our services include the following:

* Various applications to electric utilities and grid connection procedures

* Procurement of equipment such as battery storage systems and PCS (power conditioners)

* EPC (Engineering, Procurement, and Construction) and grid connection support

* Implementation and operational support for aggregation services (aggregating distributed energy resources, such as solar power generation and battery storage systems owned by households and businesses, and managing and controlling them collectively)

* O&M (Operation and Maintenance) and ongoing operational support

Operators do not need to make separate requests to multiple companies and can proceed with everything from project launch to operation and maintenance as a single, integrated process.

*Note: This service is intended for EPC contractors, not investors.

■Value Provided by WQ

At WQ, we develop development frameworks for low-voltage grid-connected energy storage facilities that prioritize project profitability while taking into account market conditions and regulatory changes.
