The government of Barbados by its recent decision appears to be committed to the $250 million Cane Industry Restructuring Project (CIRP). The goal of the project is to integrate the existing sugar industry into the emerging renewable energy project Barbados has ambitiously undertaken to diversify energy needs. Barbadian taxpayers are always the last to be informed about the finer points of public sector projects. One question which keeps surfacing is what part river tamarind will play in the new enterprise. Tony ‘Kite’ Gibbs in a comment on another blog made the following intervention.
Permit me if you please to analyze the ‘facts’ surrounding the CIRP currently in the public domain and hopefully shed a little light on the burning issues.
-
25 MW of electricity generated, 65 MW of waste heat suggest an input of 85MW and system efficiency of 30%.
-
30,000 tonnes of sugar suggest 330,000 tones of cane and 100,000 tons of bagasse of which 33% will be used internally for process steam and electricity. 67% will be converted to electricity that will be exported to the grid.
This level of exported electricity from bagasse is equivalent to an average of 5.4 MW. This means that approximately 17MW will be required from river tamarind. To acquire 17MW of power from river tamarind requires approximately 150,000 tons of river tamarind.
Based on the best agronomic practices, it is possible to get 100 tons per hectare for fuel crops such as river tamarind with the proper plant spacing. These crops have a 3-5 year cycle. The best we can get from sugar cane currently is 20 tons per acre.
When BL&P looked at this project back in 2012, their costings were based on a reference or base price of BDS$10 per million BTU’s for locally produced biomass. This works out to about BDS$120 per ton. This means that bagasse and by extension river tamarind would be worth more per ton to the farmers that the $60 per ton they are getting for sugar cane.
Finally, for those who would listen this is not a cane industry restructuring project but first and foremost an energy project. Barbados no longer has a sugarcane industry.
