benefits to customers and opportunities for utilities comparable to traditional utility investments. Customers
have more choice today and they are
going to work with third party companies if they find a reason to do so.
Utilities must find ways to work with
all segments of the business.
• Keep employees coalesced on an easily consumable vision for Grid 3.0.
Hawaii’s vision is “smarting the
grid”—sustaining a diverse resource
portfolio; managing through grid
intelligence; awareness through education, training and new tools; resilient architecture/communications;
and tangible technologies.
• Build confidence in new ways of operating the grid by providing the tools
for engineering analysis of unusual
events as well as monitoring and verification of initiatives. This includes
supporting the education of the
upcoming workforce in using cutting
edge technologies such as micro-syn-chrophasors, smart inverters and battery storage control systems.

The infrastructure will, of course, be
more complex if consumers and utilities are paid to deliver value to the grid
in ISO or DSO markets or both (Figure

deliver price signals from the markets
to the customers, enable bilateral bids
into the market, support scheduling
and settlement, and consider customer
preferences and DER.
Technologies must be cost effective,
able to scale, and in some cases, perform in subseconds. This is a tall order.
Still unanswered are the questions of
how much this infrastructure will cost
and who will pay for it.
PREPARING FOR GRID 3.0
Utility practitioners Nakafuji (HECO)
and Nachmias (ConEd) provided some
advice to their utility peers on how to
navigate toward Grid 3.0. They said:
• Focus on envisioning the most likely
future scenarios and devote compa-
ny resources to planning efforts that
involve all parts of the organization.
• Look for ways to work with custom-
ers and third party providers to bring

such as energy, capacity and frequen-
cy support. Utilities will offer new
products and services to customers,
including storage, PV maintenance
and retail markets where consumers
can trade/sell their electricity.
GRID, RESOURCE AND MARKET
Whether a utility has DER in its
future or not, it will need an enabling
infrastructure. Not every jurisdiction
will integrate large amounts of renewables and other DER in the next several
years, however, utilities and grid operators in those areas are still pursuing
grid modernization. OATI’s Ipakchi
said the bedrock technologies for reliability and grid efficiency are distribution automation, volt/VAR management and automated switching. AMI
also is essential for customer service
and grid operations, he added.
With a greater penetration of DERs,
Ipakchi reiterated what HECO has
found—operators require technologies
that provide visibility and control over
a grid where DERs are now invisible.
In addition, they need secure infrastructure that can communicate with
disparate Internet of Things equipment
like smart thermostats, smart appliances, electric vehicles, storage and smart
inverters chosen by the customer.
A more resilient grid, a topic that
has gained a lot of attention since
Hurricane Sandy, also will require systems that can interact with microgrid
controllers at customer sites. In addition, utility scale renewables require
more advanced grid technology.
When stacking resources, there
is an even greater need for bringing together customer service (DR,
