NEDO Demonstration Project in India
◘ The project is under the energy dialogue joint statement between India (Planning Commission) & Japan (METI) governments.
◘ NEDO is sponsoring for EMS demonstration Project for Telecom Tower in India
◘ “NEC and PIXELA” are the trustee of NEDO. Two companies provide necessary technology for the Project.
◘ Demonstration Project; Execute the verification of EMS for diesel fuel
reduction of Telecom Tower with partner Tower companies, VIOM and GIL.

Objectives of this Demonstration project
◘ Evaluate energy efficiency improvement, i.e. fuel and
CO2 reduction, with our EMS/LiB and Photocatalyst coat.
◘ Evaluate the costs of installation, operation and
maintenance, to examine OPEX type business model.
◘ Evaluate LiB performance
under the Indian environmental
condition.

Key features for energy efficiency
◘ Combination of Li-Ion battery
and Server-Client model Energy
Management System (EMS).
◘ EMS manages the lowest cost
power source selection and
energy efficient charge to LiB.
◘ EMS remote server realizes
centralized monitoring and
analysis of operation data and
send energy control parameter
to EMS controllers.
◘ Photo-Catalyst Coat reflects
sunshine efficiently and mitigates
temperature rise in the shelter.

Power Generation Efficiency of Diesel Generator
▌ Power generation efficiency of DG is better with higher load.
▌ High rate charging characteristics of Lithium-Ion battery is suitable
for high load power generation of DG.

Expected Benefits- Fuel Consumption Reduction
▌ Simulation result of fuel consumption of Lead Acid and EMS/LiB.
▌ PV is not included in this simulation.
▌ At off-grid area, almost 40% of fuel consumption is reduced.

Demonstration sites selection criteria for EMS/LiB
Expected OPEX reduction (w/o PV)
Grid Availability (Hours/Day)
▐Sites will be selected based on
their grid availability.
▐As shown in right side figure, fuel
reduction with our EMS is bigger
in poor grid area.
▐Five categories of grid availability.
Off grid: no grid availability.
Poor grid (1): grid is active about
3 hours per day in average.
Poor grid (2): grid is active about
6 hours per day in average.
Poor grid (3): grid is active about
9 hours per day in average.
Average grid: grid is active about
16 hours per day in average.
▐Select 4 sites for each category.
▐10 indoor and 10 outdoor sites.

The role of Photocatalyst Coat
KEY POINT;
• Reduction of the temperature rise of shelter by reflecting more than 85%
of sunlight.
• High reflectance can be maintained for more than 10 years by the
surface cleaning function.
• Pixela photocatalyst coat resists crack by wide temperature change.

Demonstration Site Distribution
• The effect of EMS and Photo-
catalyst coat are planed to be
verified at 60 sites.
• Area and site will be selected
based on climate and
grid availability.
