UTokyo EEIS
Energy System Group

Our group conducts diverse research on energy systems — including power systems, climate change mitigation, and energy policy — from an electrical engineering perspective, with the goal of realizing a safe, secure, and prosperous carbon-neutral society. Energy is an indispensable part of our daily lives, and it is essential to achieve S+3E: Safety as a prerequisite, alongside Energy Security (stable supply), Economic Efficiency, and Environmental compatibility.

In recent years, regulatory reforms such as the liberalization of electricity and gas retail markets, the separation of power transmission and distribution, and the unbundling of pipeline operations have been accompanied by the emergence of new smart grid technologies leveraging information technology. At the same time, ensuring stable energy supply and economic viability in the aftermath of the Great East Japan Earthquake, as well as reducing greenhouse gas emissions such as CO₂, remain critical challenges.

Through cutting-edge research that addresses both these technological opportunities and societal needs, we are driving innovation in energy systems. We also take into account bounded rationality — including the socioeconomic impacts of energy transitions and behavioral changes among consumers in response to energy-saving measures — enabling us to respond flexibly and swiftly to the specialized electrical engineering challenges involved in realizing a carbon-neutral society.
