One example of this is the existence of a predetermined rate-setting formula in the GP&L licence, as administered by the OPM, and in the Electricity Sector Reform Act, although the PUC is vested with the authority to determine and approve public suppliers’ tariffs. Such inefficient use of scarce human and capital resources will invariably lead to ineffective decisions and conflicting practices. Therefore, the PUC and the Guyana Energy Agency do not appear to be afforded the level of autonomy that well-functioning and transparent agencies of this nature require. Solid biomass accounts for the remaining 16 per cent of primary energy supply.
