The Uttam Group presentation discusses current trends and opportunities in sugar cogeneration, highlighting the estimated potential of 7000 MW, with challenges addressed by integrating cogeneration with distilleries. Key trends include advancements in high pressure systems, multiple fuel-efficient boilers, and the implementation of advanced control systems for operational efficiency. The presentation also outlines the company's history and project execution, emphasizing its leadership in cogeneration solutions within the sugar industry.
Trends and opportunities in sugar cogeneration
- 1. www.uttamgroup.com Presentation on TRENDS AND OPPORTUNITIES IN SUGAR COGENERATION IREDA-MITCON BUSINESS MEET Pune, Maharashtra, 17 Oct 2013 Presented by Manoj JP Kumar Manager-Marketing, Uttam Group
- 2. www.uttamgroup.com CURRENT SITUATION • Current potential of bagasse based cogeneration is estimated at 7000 MW. In Maharashtra it is projected to be at 1250 MW • Challenges in sugar production is increasingly offset by integration of cogen with distillery. • MNRE initiatives as one of the main driving force for renewable energy and decentralized generation of power. • Sugar industry is inherently suitable for cogeneration • Technological, regulatory, financial and barrier characteristic to cooperative sugar factories preventing full realization of.

- 4. www.uttamgroup.com TREND 1 – HIGH PRESSURE SYSTEMS
- 5. www.uttamgroup.com TREND 2 – MULTIPLE FUEL, HIGH EFFICIENCY BOILERS • As the cogeneration outweighs the bagasse saving mode, the need for higher fuel goes up. • Coal become necessity in capacity enhancements and in offseason operations • Sugarcane procurement becomes challenge after certain capacity depending on the region. • Boilers are now technologically more suitable for higher capacity and multiple fuel firing. • Opens up a new field of resources utilization ie. in biomass based cogeneration
- 6. www.uttamgroup.com TREND 3 – CONDENSING TURBINES /AIR COOLED CONDENSER • Earlier back pressure turbines used to default options for sugar factories. • Now it is based on requirement. • Lower back pressure results in higher power generation per unit of steam flow. • Air cooled condenser is a viable option where the water availability is or will be a concern in future. • The varied requirement is suitable addressed by extraction in different turbine stages. • These extraction are also used for regeneration across different feedwater heaters.
- 7. www.uttamgroup.com TREND 4 – RO-DM PLANT • Higher pressure calls for stringent water quality requirements. • Deposit/scaling is serious concern which not only reduces the life of the boiler but it also reduces the heat transfer hence higher fuel to generate same amount of steam.

- 8. www.uttamgroup.com TREND 5 – PLANT DCS • As we move to integrated sugar mills the need for integrated control system goes up. • Manual intervention become supplementary measure to DCS. • Continuous control, monitoring system is required to improve the efficiency, availability and operations of plant. • Emergency handing • Optimization of cogeneration system and hence better return on investment.
- 9. www.uttamgroup.com TREND 6 - REMOTE PLANT OPERATION
- 10. www.uttamgroup.com TREND 6 - REMOTE PLANT OPERATION • Data acquisition through various DCS, data-logger and other third party applications. • The data is ported through intranet/web securely for global access of information. • Data can be accessed and recorded for targeted audience. • The data is presented is form of KPI and other advanced analytics which can reported to various stakeholders in most appropriate format.
- 11. www.uttamgroup.com TREND 7– IMPROVED PROJECT MANAGEMENT AND O&M • Turnkey mode /EPC mode has gained industry wide acceptability not only in private sugar plants but also in cooperative sugar plants. • As industry moves to “cogen mode”, efficiency and availability of plant became utmost important. It needs improved team for operation and maintenance. • Annual maintenance contacts is some of the solution offered by Industry. It not only improves the ROI of the plant but aslo enhances its life
