CHALLENGES TO BPC

High costs of delivery and low tariffsRural Electrification – US$ 2,000 per household excluding generation and transmission costsTariff average Nu. 1.15 per unit/2.875 US cents (against LRMC of Nu. 2.30/5.75 US cents – now LRMC higher with recent increase in export tariff from Nu. 1.50/3.75 US cents to Nu. 2.00/US cents 5)

Conflict between social (RE and grid security) and commercial mandates
