METI Explores Measures for Faster Data Center Connections

A working group under the Ministry of Economy, Trade and Industry (METI) has begun discussions on accelerating grid connections for large-scale electricity consumers, including data centers and semiconductor plants. In some regions, a sharp increase in grid connection applications has put pressure on available capacity and extended connection timelines for large facilities.

The Agency for Natural Resources and Energy (ANRE) proposed to the working group that faster grid connection will be allowed if large facilities’ power intake can be restricted during transmission line contingencies or periods when power flows from transmission lines toward facilities (forward power flows) exceed the grid’s operating capacity. The proposal draws on the “N-1 inter-trip scheme” and non-firm connection arrangements used for generation facilities. Although these mechanisms would be difficult to apply directly to demand facilities, ANRE expects that some consumers would accept a degree of power intake restriction to connect sooner without waiting for grid reinforcement.

ANRE identified three issues for further discussion on this topic: whether power intake restrictions would be permanent or temporary, which parts of the grid system would be covered, and how costs would be allocated.

Earlier this month, the Council of Japan Growth Strategy, chaired by Prime Minister Takaichi, decided that relevant ministries and agencies would consider how to secure power infrastructure to accommodate rising electricity demand from such large facilities.

🔍 Shulman Commentary:

While METI sees that data center operators may be willing to accept power intake restrictions to get connected to the grid as soon as possible, data centers require uninterrupted energy supply. Operators would therefore need to secure alternative power sources during periods of restricted grid supply, potentially creating new opportunities for BESS and other on-site backup solutions. However, the commercial viability of these solutions would depend on the frequency and duration of restrictions.
