<Challenges Before Introducing Energy Storage> ■Challenge 1: Issues Related to Land and Trust Since the business entity was a foreign company, it was difficult to gain the trust of landowners and local stakeholders, making it challenging to proceed with land acquisition and project development. ■Challenge 2: Coordination with Multiple Stakeholders Numerous stakeholders were involved, including energy storage, PCS, EMS/communication, substation equipment, and construction companies. The coordination of specifications, delivery dates, and responsibilities became complicated. ■Challenge 3: Establishing a Business Framework in the Domestic Market Developing the project solely by a foreign operator posed high risks, necessitating the establishment of a business framework and contract scheme that included domestic companies. <What We Did (Scope of Response)> - Support for land-related coordination and negotiations - Establishment of a framework and contract scheme with domestic companies - Specification adjustments and procurement support with energy storage manufacturers - Coordination related to PCS, EMS/communication, and substation equipment - Design (basic and detailed design) - Construction (electrical, civil, and equipment) - Process management, quality management, and safety management - Oversaw the entire project as an EPC <Result> Achieved land acquisition, stakeholder coordination, and optimization of equipment specifications that were difficult for a foreign operator to accomplish alone. Successfully launched a project that generates stable revenue from idle land.
