OIL Green Energy Plans 5,000 TPD Integrated CBG and Waste-to-Energy Projects Across Haryana

September 01, 2026

OIL Green Energy Limited (OGEL), the wholly owned subsidiary of Maharatna CPSE Oil India Limited (OIL), signed Memoranda of Understanding (MoUs) with four municipalities in Haryana in August 2026 to develop integrated Compressed Biogas (CBG) and Waste-to-Energy projects across the state. The MoUs were signed in Nuh in the presence of Haryana Chief Minister Nayab Singh Saini, Union Minister Rao Inderjit Singh, senior state ministers, Members of Parliament, and officials from the Haryana government and OIL/OGEL.

It is important to be precise about what this milestone represents: these are signed MoUs for four proposed facilities, not projects that have begun construction or entered operation. Collectively, the four projects are designed to process 5,000 tonnes per day (TPD) of municipal solid waste and are expected to produce 70-75 TPD of CBG alongside 50 MW of green power once completed, figures that make the initiative a significant proposed addition to Haryana's waste-processing and clean-energy infrastructure.

What CBG and Waste-to-Energy Projects is OIL Green Energy Planning in Haryana?

The four proposed facilities will be developed across the Hisar, Ambala, Faridabad, and Gurugram urban local body clusters, with each plant sized to the municipal solid waste volumes generated in its respective cluster. The Hisar facility is proposed with a waste-processing capacity of 500 TPD, Ambala at 900 TPD, Faridabad at 1,600 TPD, and Gurugram, the largest of the four, at 2,000 TPD.

Each facility is intended to combine CBG production and waste-to-energy power generation on a single integrated site, processing the municipal waste generated locally rather than requiring waste to be transported to a centralised facility elsewhere in the state.

What is the Total Capacity and Expected Output of the Haryana Projects?

It is worth distinguishing clearly between the different capacity figures associated with this initiative, since they measure different things. The 5,000 TPD figure refers to the combined municipal solid waste processing capacity across all four proposed plants, the total volume of waste the facilities are designed to handle daily, not the volume of clean energy they will produce.

Separately, and downstream of that waste-processing capacity, the projects are expected to generate 70-75 TPD of CBG and approximately 50 MW of green electricity once fully operational. These CBG and power figures represent the anticipated output the integrated processing model is designed to extract from the 5,000 TPD of input waste, after recyclable and non-processable fractions have been separated out.

How Will the Projects Convert Municipal Solid Waste into CBG and Electricity?

The projects follow an integrated waste-processing and resource-recovery model. Under the integrated model described for the projects, incoming municipal solid waste is intended to undergo scientific preprocessing and segregation to maximise resource recovery. Recyclable fractions would be recovered, while wet and biodegradable material would provide feedstock for CBG production and suitable non-recyclable dry fractions would support the waste-to-energy component.

Only the non-recyclable dry fraction will be used to generate electricity through the waste-to-energy component. This three-way segregation is designed to maximise resource and energy recovery from a single waste stream, rather than sending all waste to biogas production or incineration.

What Infrastructure and Technology Are Required for Integrated CBG and Waste-to-Energy Projects?

A facility combining CBG production and waste-to-energy generation on a single site, at the scale proposed for these four clusters, requires several distinct but interconnected systems. Front-end waste segregation and preprocessing infrastructure, mechanical sorting, screening, and material recovery facilities, has to reliably separate recyclables, wet biodegradable waste, and dry non-recyclable waste at the volumes and speed a 500-to-2,000 TPD facility demands, since the quality of this upstream segregation directly determines how much feedstock is actually available for CBG production versus waste-to-energy generation.

The CBG production line requires anaerobic digestion capacity sized to the wet waste fraction, along with biogas upgrading equipment to purify raw biogas into pipeline- or vehicle-grade compressed biogas. The waste-to-energy line requires combustion or thermal processing equipment engineered for the calorific value and moisture content of India's mixed dry municipal waste, which differs meaningfully from waste streams in markets where waste-to-energy technology was originally developed.

Utility systems, power for on-site equipment, water for process needs, and emissions control for the waste-to-energy component, need to be sized for continuous operation at each cluster's specific capacity. And because these are four geographically separate facilities rather than one centralised plant, each site requires its own feedstock logistics and municipal waste collection integration tailored to that city's existing waste management infrastructure.

When Are the Projects Expected to Become Operational?

According to Haryana government officials, the four plants are expected to become operational by October 2028, a multi-year timeline consistent with the scale of civil construction, equipment procurement, and commissioning that four integrated facilities of this size would require. That timeline, however, should be read alongside Haryana's own history with waste-to-energy commitments.

At the same MoU signing event, Union Minister Rao Inderjit Singh referenced an earlier waste-to-energy agreement that had been signed but failed to materialise, urging state officials not to repeat that outcome. Separately, Haryana's first proposed waste-to-energy plant, planned for Bandhwari village on the Faridabad-Gurugram highway, with its foundation stone laid in April 2018 has still not begun operation years after receiving environmental clearance, according to local reporting.

These precedents do not predict the outcome of the OGEL-Haryana projects, but they are a relevant part of the context in which this fresh round of MoUs was signed, and they underscore why the October 2028 target should be treated as a stated goal rather than a guaranteed delivery date.

What Could These Projects Mean for India's CBG and Waste-to-Energy Sector?

The initiative is explicitly positioned by OIL as aligned with the GOBARdhan, the National Circular Bioenergy Scheme, as well as India's broader Waste-to-Wealth and circular economy objectives and its clean energy transition agenda. For Gurugram specifically, the project's stated aim of reducing landfill dependence carries particular local significance given the scale of accumulated waste at the Bandhwari landfill.

If the four Haryana facilities are executed as proposed, they would represent a meaningful test case for whether an integrated CBG-plus-waste-to-energy model, rather than standalone CBG plants or standalone waste-to-energy facilities, can be replicated at scale in other Indian states grappling with similar municipal solid waste management and landfill pressures.

Four Haryana municipalities have now signed MoUs for a combined 5,000 TPD of integrated waste processing capacity, a genuinely ambitious commitment, announced at the same event where a state minister warned against repeating a past waste-to-energy project that never materialised. Converting that ambition into 70-75 TPD of CBG and 50 MW of operating power by 2028 will depend on the engineering and execution discipline applied at each of the four sites, not on the scale of Saturday's announcement alone.

IMARC Engineering’s Perspective

The OGEL-Haryana MoUs represent a genuinely large-scale commitment to integrated CBG and waste-to-energy infrastructure, and the three-way segregation model, recyclables recovered, wet waste to CBG, dry waste to power, reflects a more sophisticated approach to municipal waste valorisation than many single-technology waste projects attempt.

At IMARC Engineering, we see the gap between a signed MoU and an operational facility as the stage where the technical and commercial viability of these projects will ultimately be tested, particularly given Haryana's own prior experience with waste-to-energy commitments that did not progress past the announcement stage. Facilities of this kind require feasibility studies that validate real waste composition and volume data for each specific municipal cluster, engineering design that correctly sizes segregation, anaerobic digestion, and waste-to-energy systems against that actual feedstock mix, utility and emissions infrastructure suited to each site and coordinated project execution across four geographically distinct locations simultaneously.

As India works to scale waste-to-clean-energy infrastructure, projects of this type will require policy support to be matched by detailed feedstock assessment, technology selection, environmental planning, utility integration, engineering, procurement, construction management and commissioning discipline. For the Haryana projects, these execution factors will be central to converting the MoUs into operating facilities within the stated timeframe.
