Rikiya Abe (Ph.D.) is the CEO of DG Capital Group Corporation. The company, along with its subsidiaries, produces grid-forming inverters (DGR) using digital grid technology and operates AC main grid with grid forming that supplies synchronizing force and inertia.  DGR also provides primarily renewable energy sources with a duplicated DC sub-grid redundant to the AC grid. They also design small wind turbines and DC generators. These were established to incorporate renewable energy sources into power systems with many constraints. Dr. Abe also serves as the representative director of the non-profit Digital Grid Consortium, which promotes digital grids through educational activities and consulting. With years of experience as an electrical engineer at J-POWER, a Japanese wholesale electricity company, Dr. Abe dedicated his research and development efforts to the concept of digital grids as a specially appointed professor under the direct control of the president of the Universityof Tokyo since 2008. In 2012, he founded WASSHA, which provides renewable energy in un-electrified areas. Furthermore, he established the Digital Grid Company in 2017, constructing a private market for energy and environmental values in Japan, facilitating transactions between many power generators and consumers.
