Green Energy Consulting Co., Ltd. (GEC) is an advisory firm based in Japan, supporting decision-making at the early stage of infrastructure assets.

We work across solar PV, grid-scale battery energy storage systems (BESS), data center–related assets, and other infrastructure assets with similar early-stage structures.

By organizing key issues specific to the early stage—such as land, power, regulation, and stakeholder coordination—we help our clients reach a position where projects and conditions can be properly evaluated.
