This study updates and takes stock of recent developments in bagasse-based electricity co-generation in the global sugar cane industry. It also assesses potential increases in power generation till the end of the current decade. A survey of installed cogeneration capacity in the sugarcane processing sector as well as existing development plans shows that bagasse-based production of electricity for export to the national grid is fast becoming a major activity of sugar cane mills. An increasing number of mills in a growing number of countries are already involved in or planning to start in the near future electricity production in excess of captive consumption. Indeed, since 2009 the number of sugar mills exporting energy to the grid has more than doubled, reaching 490, while the overall installed capacity has nearly doubled, reaching 12,644 MW. Furthermore, the available information on expansion potential allows us to project a more than 100% increase in the global generating capacity of the sugar cane industry by the end of the current decade. A possibility of bringing an additional, stable revenue stream leading to an increased competitiveness is particularly important taking into account the amplified volatility of the world sugar market and, hence, sugar export earnings of the sector. Crucially, bagasse cogeneration projects have short development periods as technologies used are proven and well established. It is also important to note that, following a substantial increase in sugar cane production, the amount of bagasse available for co-generation has also grown considerably in several countries.
The first part of the study is dedicated to examining the current status and global outlook for co-generation in the sugar cane processing sector. The second part analyses the current situation, co-generation potential and legal framework in individual countries. First, we focus on the industries where co-generation has already become a major activity (Brazil, Colombia, Guatemala, India and Mauritius). Then, the information available in the public domain on developments in 32 other countries in Africa, Asia, North, Central and South Americas as well as Oceania is also analysed.
