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.

LiB module and Photocatalyst Coat

▌ Photocatalyst Coating sample

▐ LiB module sample (3.3kWh)

6 units per site for this demonstration


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.

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.





Average grid: grid is active about


▐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.
