Background
NEC showcased the capability of its EMC solution to one of the
large retail store chains in Southeast Asia
Challenges of the customer
The client spends significant sum annually on energy costs and
lacks visibility on the breakdown of energy usage. They require
an energy management system that can keep track of energy
consumption at the same time optimize their HVAC system which
consumes significant percentage of total energy cost
Solution
NEC provided an energy management & control system with
unique HVAC control features capable of taking inputs from
multiple temperature sensors and utilizing its intelligent control
algorithm. Tracking of energy consumption is provided through
EMC visualization software
Results
• Reduction in total energy consumption by more than 10%
• Reduction in HVAC consumption by 30% - 35%
Intelligently measure, monitor
and control energy consumption
NEC’s Energy Management products and consultation services combined with an extensive portfolio
of lithium-ion based energy storage systems position NEC as a leading Smart Energy solutions
provider in the APAC region — contributing to efficient energy use and lower greenhouse emissions. Energy consumption visualization and analysis
With ever increasing electricity prices and the driving need
to improve energy efficiency and reduce carbon footprint,
energy management & control has become an integral
part of every organisation today.

NEC Energy Storage
Photovoltaic
NEC EMC has an adaptive energy controller that is capable of
controlling both demand and supply of energy in order to reduce
customers’ energy costs and OPEX.
The controller can automate a variety of energy optimisation
applications, including peak shaving and energy efficiency
enhancement. Compared to the conventional peak shaving approach
it can achieve savings of up to 35% in HVAC consumption.
It synergizes with Starlight™ meters receiving inputs from meters
and directly interfacing with energy storage and generation systems.
Coupled with load profile and utility tariff data, the controller
calculates the most cost effective way to utilise generation and
storage, translating it into battery charge/discharge commands, while
regulating battery system usage – maximising the life of storage
assets.
NEC EMC works best with NEC’s Energy Storage solutions, featuring
advanced Lithium-ion battery technology robust enough to handle
large numbers of charge/discharge cycle.
Applications
Automated Meter Reading (AMR)
Meter data is collected in near real-time
at a central server, reducing the need
for manpower to take periodic readings.
Reporting and analytic tools allow users to
make sense of their energy consumption
and take positive steps towards improving
their energy efficiency, while still providing
a comfortable living environment.
Tenant Energy Management and
Portfolio Benchmarking
Utilities companies and property landlords
are able to monitor each individual tenant’s
energy consumption, and with integration
into their billing system, automate the
monthly billing process. The technology
also enables an analysis of energy
performance for each property, allowing for
energy forecasting and benchmarking.
Telecom Shelter Monitoring for
Telecom Operators
Operators can monitor the health of shelter
equipment and predict power consumption
trends. Real-time data combined with
forecasted profiles can be utilised to control
and optimise the use of grid power, diesel
generation, battery systems and renewable
sources – minimising the total cost of
energy to the operator.

Key Features of NEC EMC Solution
“NEC EMC manages the various energy sources within
the facility to optimize total energy cost at any given
time. The cost of energy is put into the controller so that
control decisions are evaluated from cost perspective.”
NEC Energy Management & Control (EMC) provides an end-
to-end solution for customers’ energy management needs. It is
capable of demand side management resulting in energy
savings by optimizing air conditioning, lighting and equipment
operations. On supply side management, it is capable of
managing different sources of energy such as utility grid,
battery systems (VRLA, Li-ion etc.), diesel generator set and
renewable sources.
NEC EMC gathers data through temperature sensors and
power meters, strategically placed in a facility that enables its
powerful controller to maintain equipment performance while
minimizing energy consumption.
The NEC EMC visualization software empowers users with
complete visibility of their energy profile, allowing them to
track, analyze and forecast their energy performance, as well
as make informed decisions and take action to reduce energy
use and lower costs.
