Abstract: . . .  3,995 223 0 0 0 0 0 It is evident that the policy measures enacted over the past decade and the favourable response of the sugar industry in implementing energy saving measures has had a positive incidence on bagasse saved. It is observed from the table above that Beau Plan, Constance and Britannia saved an increasing amount of bagasse over the years to benefit from the relief granted on export duty payable but did not invest in bagasse power plant. On the other hand, the other factories, after having invested in energy conservation measures in the factory, went into energy cogeneration. DRBC erected a power plant in 1997, Belle Vue in 1999, MDA in 1997 and Riche en Eau as from 1994.

Table 5 shows the electricity generated by source over the years 1970-1998. Table 6 shows the impact of policy and fiscal measures on bagasse energy generation.
