Smart grid costs (cumulative) to total ¥5,093bn in 2030
We have calculated the approximate costs required for electric power companies
to modify systems to accommodate a significant rise in the number of households
using solar-source energy. Excluding battery cell costs, smart grid costs are within
the range of normal capex. However, battery acquisition costs will be no small
burden for electric power companies. Although conventional wisdom assumes
batteries will be needed, we revisit this assumption and suggest that alternatives
for system stabilization should be examined.

Definition of smart grid for the purposes of this report
In this report, a smart grid in Japan is defined as “an electric power network
capable of accommodating a large-scale input of new energy.” Related costs are
capital expenditures for the network associated with this large-scale input of new
energy. Equipment required for Japan’s smart grid includes batteries, switchgear,
transformers, smart meters, and communication lines.
Increased solar generation volume, system augmentation necessary
The government is, from a policy perspective, supporting policies to promote the
spread of solar power generation to realize a low-carbon society. Electric power
companies have to purchase excess solar power generated by households.
Reverse power flow within the grid is already occurring (p. 2), and to the extent
that the volume of solar power generated by households and input into the grid
rises in the future, fluctuations in the electric power volume within the electric
power grid will be exaggerated by changes in weather and are expected to exceed
the capacity of the current system. The existing power supply system will have to
be modified.
Composition of smart grid-related costs (cumulative) as of 2030
Our calculation is as follows: (1) batteries, ¥2,512.1bn, (2) switchgear, ¥224.2bn,
(3) transformers, ¥742.6bn, (4) smart meters, ¥1,076.1bn, and (5) communication
lines, ¥538.0bn, for a total of ¥5,093.0bn.
Will batteries really be necessary?
Battery acquisition costs will be no small burden for electric power companies. It
is possible that these costs can be passed on through electric power rates.
Nevertheless, the question remains: will batteries really be necessary? We see
alternatives that deserve consideration, including: (1) closer cooperation among
the electric power companies. For example, when there are large amounts of
reverse solar power flow in the Kyushu region, some power could be transmitted
to regions with a large electricity consumption capacity, and (2) measures to
reduce power station utilization rates when large amounts of reverse current are
generated from solar power within a region.
Valuation and risk
We base our valuation on an EV/EBITDA multiple. In instances where multiples
declined markedly due to a correction in the electric power sector, we used
dividend yields. We use weighted averages in both cases for the five majors we
cover. Upside risks include: (1) the economy recovering more rapidly than
expected and (2) power demand from industry not declining as much as expected.
Downside risks include a dip in nuclear power utilization. (Details, p. 3.)
