What is ESCO?
ESCO is acronym of Energy Service COmpnay. This is a company which is ready to execute energy conservation projects on performance basis. i.e. the revenue model of the ESCO is based on the energy saving performance of the equipment supplied by ESCO. This company is confident about the equipment & has domain knowledge of the applications, which makes it confident about energy saving predictions.
As the energy saving is the key concern from the environment & competitiveness perspective , lots of inventions in the technologies target energy saving as one of the major objectives .In this process , everyday , we come across new technologies which claim energy saving . However, the customer is hesitant to go for this technology due to two major reasons:
- 1. Higher investment cost
- 2. Lack of confidence on the technologies & also lack of trust with the technology vendors.
This aspect results into huge loss of energy saving opportunities.
So, there is a need of an entity, which creates this confidence & trust about technologies. In India, at present there are approx... 150 ESCOs registered with BEE (Bureau of Energy Efficiency), with less than 25 active. On the contrary, China has more than 5000 ESCOs, which had been instrumental in changing the Energy Efficiency scenario in China in last 10 years.
Realising this, Govt. of India has taken initiatives to promote ESCO & has offered few benefits for ESCOs to sustain.
How does ESCO work?
There are two prevailing models of ESCO business.
01. Performance sharing model
The supplier invests in the project& accepts performance based revenue per month for the contractual period. This model suits to the energy user , who does not want to invest for some reason
The energy user invests in the equipment. However, the supplier guarantees the performance by accepting to pay per month, if the energy saving in the month is less than the committed value. Vice versa, if the energy saving is found to be more than the committed one, and then the energy user will pay the difference to the ESCO.
Types of ESCO
Based on the competencies of the company, the ESCOs can be classified as follows ..
01. Product based ESCO
These companies are manufacturers of an energy saving product. So, such product ESCO companies offer their product on ESCO model to increase the sale of their products
02. Finance based ESCO
These companies are basically financing companies having access to some funds. As they foresee a better return from ESCO business model, they want to invest in it. They normally tie up with energy auditors or manufacturers of energy saving products to confirm the energy saving before entering into the contracts
03. System ESCO
These are the companies which have domain expertise of a particular field such as HVAC, Lighting, Paper mfg., pumping. They are aware of various ways to reduce the energy consumption in a process , which can be just a process change or intervention by multiple technologies of energy saving .SO, they will not only offer a product but will take responsibility of all the system related changes in a process.

Small HVAC ESCO
Energy consumption on HVAC is a major pain area for all types of industrial & commercial establishments. Small HVAC systems are defined as individual / isolated air conditioners working at different areas in an installation.
Major technologies used are:
01. Refrigerant additives for effective heat transfer
02. Optimised control of compressor
03. Occupancy control
Large HVAC ESCO
Large HVAC system is defined as an HVAC installation where the centralised chillers are used.
Major technologies used are:
01. High efficiency chillers
02. Effective heat transfer
03. High efficiency AHUs
04. Optimisation of heat transfer in fresh air
05. Insulated roof paints
06. Occupancy sensors
