Energy Efficiency Solutions
Services designed to enable your business to lower energy costs and reduce environmental impact while maintaining or enhancing operational efficiency.






























1. High-Efficiency Chiller Replacement
We specialize in the supply and installation of high-efficiency chiller systems, serving as an authorized distributor for world-leading chiller brands such as Multistack and Haier. Our service covers various advanced chiller types, including flexible modular chillers and innovative Oil-Free Magnetic Bearing Chillers. This cutting-edge technology delivers significant energy savings and superior operating reliability.
2. Cooling Water-as-a-Service (CAAS)
This is an innovative, turnkey solution for cooling water supply. Under the CAAS model, we take on the full investment required to upgrade and optimize the client’s existing chiller plant for maximum efficiency. We then sell the cooling water based on usage under a long-term service agreement. This solution effectively relieves clients of significant Capital Costs (CapEx), converting them into predictable Operational Costs (OpEx).
3. Energy Audits and Retrofits
We provide comprehensive assessments through in-depth energy audits. This service clearly identifies areas of energy waste and opportunities for efficiency improvement within your building or facility. Following the audit, we propose the most suitable Retrofit plans, ensuring clients can achieve tangible reductions in energy costs and enhance the sustainability of their operations.

Frequently asked questions
What are the benefits of MEP Service?
Controlled carbon dioxide emissions making your building more energy-efficient, whether you are still at the development stage or are retrofitting a historical building.
Reduction in overall energy consumption, improving building performance through system components.
The utilisation of sustainable energy reducing the strain usually put on the power grid during peak periods by commercial buildings.
Conservation of water usage through strategies such as low-flow toilets and touch-free taps.
What financial options does KG SOLAR offer for large-scale solar projects?
KG SOLAR offers two main investment options (EPC):
Direct Purchase (Customer Investment): The customer purchases the solar cell system outright. Customers can choose to make a standard payment or opt for a solar loan/credit facility from leading banks to maintain financial liquidity and receive government incentives.
KG Investment (PPA – Power Purchase Agreement): KG invests in and installs the solar system for the customer. The customer benefits from using electricity at a lower rate than the utility provider’s tariff. Upon contract completion, the customer immediately gains ownership of the solar system.
Is installing a solar cell system truly worthwhile? How much can be saved and how long is the payback period?
It is absolutely worthwhile! If you are a factory or business that uses electricity 5-7 days per week, the electricity rate from the solar system will definitely be lower than the rate from the utility provider. You can save up to 500,000 – 1,000,000 THB per month*, with a payback period within 1 – 5 years*.
*Note: Electricity savings and the payback period for solar rooftops depend on the size of the installed system, the investment model, and the specific electricity usage profile of each factory/business
What was the initial starting point of K.G. Corporation Co., Ltd.?
The starting point for the company’s founding was in 1988 (B.E. 2531), initially operating a business related to Electrical Installation.
Subsequently, the business expanded and developed into a diversified corporate group that currently encompasses various sectors:
– MEP Systems (Design, Installation, O&M)
– Renewable Energy (Solar & Battery Solutions)
– M&E Engineering
– KG Trading
How does the company's system design support the application for Green Building Certification, such as LEED or TREES?
It can be done. We strictly design our MEP systems and Renewable Energy solutions with Green Building Certification requirements in mind, particularly concerning energy reduction, water management, and indoor air quality control. This helps our clients’ buildings achieve certification goals more easily.
Do KG Corporation's various services include support for handling documentation with government agencies and relevant authorities?
Yes, they do. For solar cell installation projects in the business and factory sectors, and for other KG services, documentation must be processed with multiple agencies, such as:
The Electricity Authority (Provincial Electricity Authority – PEA or Metropolitan Electricity Authority – MEA) for grid connection approvals.
Local/Government Agencies (e.g., local administrative organizations, municipalities) for construction or building modification permits.
The KG SOLAR team will manage and facilitate the preparation and submission of these documents to ensure the process is compliant and completed as quickly as possible.
