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.
