Global energy direction that aims to transition to clean energy to solve the global warming crisis

Combined with the volatility of fuel prices in the world market.

causing the proportion of electricity generation from renewable energy to increase

while electricity users turn to generate electricity for their own use with solar cells installed on the roof or Solar Rooftop to save costs

Thammasat University (TU) is another educational institution that promotes clean energy use.

By installing Solar Rooftop on various buildings within Thammasat University, Rangsit Campus, up to 44 buildings with a total installed capacity of 6.28 megawatts, resulting in some periods of electricity generated from the Solar Rooftop therefore exceeding the demand.

TU has joined with the Electricity Generating Authority of Thailand (EGAT) to bring a microgrid system and an electric power management system to help solve such problems under the TU EGAT Energy project, which is an innovative testing project that uses technology. To support energy services (ERC Sandbox) operated in conjunction with the Energy Regulatory Commission.

The goal is to test all four aspects of energy services, namely 1) to study the new electricity market structure, Peer to Peer 2) the new service fee structure, Net Metering Net Billing, 3) innovation of energy management systems in the microgrid (Micro Grid) and 4) energy storage systems.

Solve the problem of excess power with the energy management system

EGAT has implemented an energy management system for generating electricity from the Solar Rooftop of 8 buildings in the Social Science Learning Group, namely the Social Sciences Learning Building.

This is the area that uses the most electricity in the university.

by connecting to the energy storage battery installed by EGAT.

explained that the Energy Management System is an innovation developed by EGAT in the form of a Web Application to monitor the production and use of electricity from solar cells in real time.

This makes it possible to manage the production of electricity efficiently.

“Before this project, even the university had installed Solar Rooftop distributed throughout the university and supplied electricity to the building.

But they don't know how the energy produced in a day looks like, but when EGAT installs an energy management system, it will know immediately what form of energy use is currently available, both per room, per building and How much carbon dioxide does each group have?

and how much the cost can be reduced.”

When solar cells produce more electricity than the demand for electricity

The system will direct those excess electrical energy to be stored in the battery.

Including during the low cost of electricity (Off Peak) from 10 PM to 3 AM, the price of electricity is 2.61 baht per kilowatt-hour.

The system will automatically charge the stored electricity in the battery.

To bring the stored electricity to supply electricity to the building when the demand for electricity is high.

or during the period with high electricity costs (On Peak) from 14:00 to 18:00 hours, the price of electricity is 4.23 baht per kilowatt-hour.

Thus, it can help save electricity costs and strengthen the stability of the electrical system when the power produced from solar cells is lost.

Pilot electricity trading between buildings

In addition, EGAT has also brought the Peer-to-Peer Energy Trading platform, which is an electricity trading system between buildings, to be tested in this project.

When some buildings generate excess electricity from solar cells instead of storing them in batteries, they can be sold to buildings that generate less electricity than they need.

Including the ability to issue a receipt when the purchase of electricity is completed.

In order to support the new electricity market structure in the future, there will be more electricity trading between electricity users.

Reduce electricity bill 4 hundred thousand baht per year

Prof. Dr. Nattapon Sangaroon, Assistant Rector for Rangsit Center Administration for Quality of Life,

TU, revealed that the TU EGAT Energy project has made the university's energy management system more efficient.

It saves over 400,000 baht per year on electricity bills, especially by storing excess energy produced from solar cells to be used when needed.

This is in line with the approach to driving towards becoming a TU Smart City.

“Thammasat University is ready to be a model for educational institutions or other agencies that are interested in renewable energy.

by preparing to develop and establish a learning center for innovation in energy management of the university

which can respond to policy issues at both the organization, national and international levels

whether it is the United Nations energy-saving goal

Greenhouse Gas Reduction

Importantly, everything we do

is to contribute to society with sustainable use of clean energy.”

The TU EGAT Energy project is therefore another important step leading to the development of EGAT's Smart Energy Solution to meet the needs of various power users.

reduce energy consumption

Meet the trend of using electricity in the new era towards more efficient use of clean energy.
