“Generating for Generations with Sustainable & Responsible Manner”

Dr. P. Anbalagan

India’s Power needs are soaring, fueled by a growing population, rapid urbanisation, and ambitious economic plans. Meeting these demands while responsibly stewarding the environment and securing its energy future for generations to come requires a multifaceted approach. Energy is a key source of economic growth because many production and consumption activities involve energy as a basic input. While meeting the energy demands of the present generation, it is essential to consider the needs of future generations. Striking a balance between economic growth and environmental preservation is the hallmark of responsible power generation. This involves ongoing research, policy development and a commitment to adopt emerging technologies that align with sustainability goals.

Responsible power generation involves harnessing energy in ways that minimise environmental impact and prioritise long-term sustainability. Moreover, responsible power generation extends beyond the choice of energy sources. It encompasses efficient energy use, innovative technologies, and community involvement. Smart grids, energy storage solutions, and demand-side management play pivotal roles in optimising power consumption and reducing waste.

India set up a target of 500 GW of electricity from non-fossil fuel-based sources by 2030 and is aiming to have NET ZERO emission by 2070.

MAHAGENCO OVERVIEW:
Maharashtra State Power Generation Company Ltd (Mahagenco) was established in 2005 after the restructuring of the Maharashtra State Electricity Board (MSEB) and as on date Mahagenco has a total balanced power generation capacity of 13170 MW comprising Thermal power capacity of 9540 MW, Gas 672 MW, Hydro 2580 MW and Solar Power 378 MW. Mahagenco is the company with the highest power generation capacity among all State Power Generation Companies in the country and Mahagenco is the second largest power generation company in India after NTPC Limited.

The emerging scenario of the Power sector in India provides significant risks to conventional generators and at the same time provides ample opportunities of growth through integration of technologies with renewable power. Accordingly, Mahagenco has identified its areas of weaker area of various projects as well as existing plants activities which requires consistent improvements with corrective, preventive, predictive & innovative actions – Essential Renovation & Modernization, Spares & Resource Management, Coal availability and its competitive sourcing are the top priority elements. At the same time, Mahagenco is planning its O&M initiatives in order to achieve regulatory parameters and also to reduce disallowances to ensure full fixed cost recovery.

Mahagenco has an objective of building a ‘Green Maharashtra’ using non-conventional green energy and providing maximum and cheapest electricity to the people of Maharashtra. Considering the future need of green energy, Mahagenco is taking various measures to increase the capacity of Renewable Energy projects including solar projects. As per the Renewable Energy Policy of Government of Maharashtra, the following activities will be implemented in the next few years with the aim of developing various eco-friendly renewable energy projects and to meet the increasing demand of electricity in the state of Maharashtra.

Mahagenco is focusing on the RE bundling scheme as per guidelines of the Ministry of Power, Government of India. Bundling scheme is helpful to achieve a minimum 43.33 % share of RE energy up to 2029-30 by minimising thermal energy with renewable energy to reduce environmental impact. Accordingly, a minimum target of 1692 MW capacity has been given to Mahagenco up to 2025-26. In addition to bundling, MoP has issued a resolution dated 27.02.2023 regarding 40 % RGO for units commissioned after 1st April 2023. Accordingly, Mahagenco has planned to commission 2234 MW solar projects under bundling & RGO schemes by year 2026.Mahagenco will also make a foray into Energy Storage Solutions such as battery storage & Pump Storage plants, an emerging area which can play an important role in grid integration & balancing of variable generation sources.

Mahagenco is committed to green energy generation in line with guidelines from GoI/GoM from time to time for achieving the further goal of De-carbonization to minimise carbon footprint. The CMAGF scheme will help to reduce the existing load on agriculture feeders resulting in minimum distribution losses and day time reliable green energy to the farmers. Mahagenco Renewable Energy Limited is formed as a new RE Company which will further help to diversify the business of Mahagenco.

Mahagenco has undertaken a number of measures to control pollution, hazardous waste management, and ash utilisation. The aim is to meet the norms prescribed by the competent authorities and play the role of an environmentally responsible organization. The basic thrust areas for Mahagenco in this regard are environment protection, ash utilisation, community development, and energy conservation. Mahagenco believes in the up-lift and empowerment of the local communities in and around its project sites, especially with regards to their human development index.

Mahagenco strongly believes in conservation of natural resources through maximum recycling of resources. Towards this purpose, Mahagenco has ash water recovery systems, effluent treatment plants, and the like. Rainwater harvesting is also being practised to support water criticality. A Green belt has been developed by planting a large number of trees in the power station colony area of Mahagenco. Tree plantation is one of the most effective tools for elevation of deteriorated environmental conditions. All TPSs of Mahagenco meet the norm of minimum 33% tree plantation in open areas.

While conserving the environmental aspects, a sincere effort is being made by Mahagenco to bring the carbon footprint from its power stations to zero or negligible levels. The system of continuous monitoring of air quality has been installed at different places in the vicinity of thermal power stations.
