Buhari said he was disappointed with the services of the nation’ s power distribution companies .
He said his regime had spent N1 . 7 tn to supplement tariff shortfalls .
He said this could no longer continue.
Buhari said , “ Let me say frankly that like many Nigerians , I have been very unhappy about the quality of service given by the Discos, but there are many constraints including poor transmission capacity and distribution capacity .
“ I have already signed off on the first phase of the Siemens project to address many of these issues .
“ Because of the problems with the privatisation exercise , government has had to keep supporting the largely privatised electricity industry .
“ So far , to keep the industry going we have spent almost N1 . 7 tn , especially by way of supplementing tariffs shortfalls . ”
He said the hike in electricity tariffs would be based on improved power supply .
