What’s inside this report?
Japan's power sector is in flux due to liberalisation and overcapacity. This is challenging the utilisation of gas generation, which is less competitive than coal.
In April, Tokyo Gas announced a 10-year deal with Shell to supply LNG using a coal-linked pricing formula – a rare move that broke the mould of the typical oil-linked contracts that have been used for decades in the market.
In this insight, we unpack the significance of the deal for Japan’s power sector and for LNG.
Contracts that make use of coal-indexation, such as the Shell/ Tokyo Gas deal, could be an important step to enable gas to better compete with coal-based power generation.

Why buy this report?
While the details of Shell’s contract with Tokyo Gas have not been made public, we explore how the deal could have been structured.
We apply our deep understanding of commodity dynamics, local energy dynamics and power market design to consider:
- How could a coal-indexed LNG contract be priced?
- What LNG price is required for existing gas plants to displace new coal power plants?
- What carbon price is required for existing gas plants to compete against existing coal?
