Task 15 – Case Study – Paradip Port Substitution of Cooking Fuel Project – India

Paradip Port Substitution of Cooking Fuel Project – India

This is the 6th article in a series highlighting the case studies of DSM Task 15, Network Driven DSM. This Task demonstrated that DSM can be successfully used to support electricity networks in two main ways:

1) by relieving constraints on distribution and/ or transmission networks at lower costs than building ‘poles and wires’ solutions, and

2) by providing services for electricity network system operators, achieving peak load reductions with various response times for network operational support.

The Paradip Port Substitution of Cooking Fuel Project was initiated and funded by the Paradip Port Trust.

The Trust was set up by the Government of India to administer the port of Paradip, an autonomous body under the Major Port Trusts Act, 1963.  The Trust purchases electricity in bulk from the Grid Corporation of Orissa Limited (GRIDCO) and then supplies electricity directly to its employees for household use.  The Trust supplied electricity to its employees at a subsidized average flat rate of INR132 per month and had to bear an annual loss of around INR31 million.

The objective of the Paradip Port Substitution of Cooking Fuel Project was to reduce system peak demand by introducing LPG as a domestic cooking fuel through replacing electric stoves used by Trust employees.  The project was targeted at cooking in the residential sector because this activity comprised approximately 60% of the electrical usage in each household.  Almost 90% of the 3,592 households in the residential facility provided by the Trust used electric stoves for cooking, adding 3 to 4 MW to the electricity demand.

The maximum contract demand of Paradip Port under its supply contract with GRIDCO was 7.5 MVA.  The peak demand often reached 9 to 10 MVA, resulting in penalty charges.  The industrial load did not exceed 4 MVA at any point in time but the domestic use exceeded the contract quantity by 2 to 3
MVA during peak periods.  Because electric stoves were the largest contributors to the peak demand, replacing these with LPG cooking stoves would result in considerable electricity and cost savings.

Description of Project

The replacement package offered by the Paradip Port Trust included both stoves and LPG cylinders.  An LPG cylinder bottling plant, with assured gas supplies from Paradip Port, was also established in the area to ensure an adequate supply of LPG cylinders.

The Trust offered its employees the following incentives to move from electric stoves to LPG stoves:

  • 100% subsidy on purchase and installation of an LPG stove;
  • 100% reimbursement of the cost of the LPG cylinder;
  • reduction in the flat rate electricity tariff from INR132 to INR80 per month;
  • a limit on electricity consumption under the flat rate tariff fixed at 108 kilowatt-hours per month; consumption above this limit to be charged at the full price of INR3.37 per kilowatt-hour.

As the two-part tariff was introduced, meters were installed to monitor the electricity consumption by individual households and to enable accurate charging for electricity consumption.

The Paradip Port Trust was the main stakeholder responsible for the financing, procurement, implementation and monitoring of the project.  The housing department of the Trust was responsible for the entire project.  The major investment in the project was the procurement and installation of the LPG stoves and electric meters in individual households.  The entire cost was born by the Trust and was recovered through electricity and cost savings.

The end-users in this project were employees of the Trust and thus directly connected to the project implementor.  Therefore, it was relatively easy for the Trust to create awareness, and market and control the project.  The Trust motivated the end-users in the stove replacement project through various awareness programs.


The Paradip Port Trust replaced a total of 2,874 electric cooking stoves with LPG stoves.  The morning peak was reduced by 2.3 MW and the evening peak by 3.2 MW.  The project resulted in ongoing annual savings to the Trust of INR15 million.

The total implementation cost for the Paradip Port Substitution of Cooking Fuel Project was INR19.7 million.  The additional cost of running the project was identified as INR200,000 per year.  The entire cost was born by the Trust and was recovered through electricity and cost savings.  A detailed breakdown of the implementation cost is shown in Table 1.
