Japan Energy Challenge 2019

5-8 August 2019, London

What​ ​we​ ​do

Japan Energy Challenge provides a series of energy innovation programmes aimed at helping international energy sector companies demonstrate their products with their first major customer in Japan - the world’s most dynamic and exciting energy market. While our activities are ongoing, our central event is our annual Venture Competition held in London. As part of JEC2019, we also are hosting a Startup Pitch Competition to promote promising ventures in the pre-seed/seed/Series A stage.

We aim to be the fastest and best option for these promising companies to begin unlocking the massive opportunity in the area. We succeed when our network members find clients, pilot projects, sales opportunities, and funding to help bring their products to Japan.

Our Programs for 2019

Why​ ​Japan?

For innovative energy sector companies starting their global expansion, Japan is a massive opportunity that cannot be ignored.

With over 900 TWh of annual electricity consumption, Japan is the fourth largest consuming nation in the world. It’s also in a period of rapid political, industrial, and technological change.

In March 2016 - one month before liberalising - Japan’s electricity market size was $150B. Nearly two years later, the market is highly competitive with the former incumbents and dozens of new entrants fighting for market share and new technologies that will give them an edge.

In 2015, Japan became largest procurer in the world of smart-metering solutions. Every household - nearly 80M in total - is expected to have a smart-meter installed by 2025.

These advancements have made Japan a hotbed of change and opportunity. However, entering the market from overseas can be challenging. The Japan Energy Challenge is a program designed to select promising technologies and match them with companies in the Japanese energy sector who are looking to innovate.
