the reform established chubu electric Power's role as a
competition-neutral entity in the electricity wholesale and
retail market.
On the other hand, the number of distributed energy
resources (ders), particularly solar [photovoltaic (PV)]
generation, increased rapidly as a result of the feed-in-tariff
(fIt) scheme implemented by the Japanese government
in 2012. More than 30 gW (nameplate capacity) of solar
generation are already connected to the t&d network. this
renewable energy penetration causes some serious technical
problems such as the uncertainty of wide-area demand-supply balancing, voltage fluctuations, and two-way power flows
in local distribution networks.
t&d utilities must maintain and replace aging infrastructure such as transmission lines, substation transformers,
circuit breakers, distribution lines, and pole transformers,
march/april 2018

which were installed during the high economic growth
period after World War II. to cope with these issues, t&d
utilities need to establish new solutions, such as conditionmonitoring diagnosis and risk management techniques with
due consideration to the entire power network topology
required to optimize t&d equipment repair and replacement planning.
comprehensively addressing the three issues is quite
challenging for Japanese electric utilities, and cePcO is
exploring solutions using information and communication
technology (Ict).

Overview of CEPCO
currently, ten vertically integrated utilities including
cePcO dominate the Japanese electricity market. cePcO
is the third largest electric utility in Japan with 10.74 million
