1. THE MAUI TO OAHU
INTERISLAND UNDERSEA POWER CABLE
The use of a submarine cable to interconnect remote renewable
generators to Oahu makes sense only if sufficient renewable
resources cannot be sourced on Oahu. In the preferred plan, it
appears that the 40% RPS1
goal by 2030 can be met with a
combination of additional wind, utility scale solar and biofuels,
without the need to import renewable generation from other
islands. Therefore, for purposes of this PSIP, the Companies2
have not considered HVDC submarine cables to access
additional renewable resources. If in the future, this key
planning assumption proves to be incorrect, an inter-island
cable could become feasible for this purpose. This planning
assumption does not preclude proposals for neighbor island-
sited renewable generation to serve Oahu through a submarine
cable, provided that such proposals are cost effective and
reliable, relative to other options available to Hawaiian Electric.

Development of the Smart Grid - No. 1 Priority
MECO ACTION PLAN – MODERNIZE GRID - MAUI
Smart Grid Purpose: To transform the existing grid into
a “smarter”, more efficient, more reliable grid that
integrates more renewable energy through the use of
various technologies and capabilities and provide more
information and options to customers with the overall
goal of reducing costs and improving service to our
customers. The initial Smart Grid deployments will be
functionally and/or geographically targeted, installing a
limited number of advanced grid technology components
to obtain and assess some of the high value benefits
expected from smart systems.

5. If these targeted deployments are successful in providing
the benefits that are anticipated and discussed in the
Smart Grid principal issue section, then these programs
can be expanded through the action plan period,
contingent upon Commission approval.
Scope: The MECO Smart Grid five-year action plan
includes Advanced Metering Infrastructure (AMI)
including Conservation Voltage Reduction (CVR) and a
Pre-Pay program.
Smart Grid Demonstration Projects
The Companies will continue to implement and support
the ongoing smart grid demonstration projects on Maui
leveraging outside funding from sources such as the U.S.
Department of Energy (DOE) and the New Energy and
Industrial Technology Development Organization
(NEDO) of Japan.
The utilities’ role is primarily to provide oversight and
project management support in 2014 and 2015 after
which the demonstrations will conclude.
New systems and capabilities that are developed through
these projects will then be assessed to determine if the
deployment should be expanded to obtain greater benefits
to the system and our customers.

“To best meet the broad array of energy needs, the actions the
Companies have developed are equally complex. Implementing
one action oftentimes affects another action. Understanding the
relationship among all of these actions enables the Companies
to not only mitigate the downside of taking one action at the
expense of another, but also to execute these actions in a way
that best meets the current and future energy needs of our
customers.”
