when I did 1 year OJT before at Nestle in Laguna (that was in the 90s) they had a huge diesel genset na mas malaki pa sa admin building ng business namin...

at that time, the logic then kaya nag genset sila.. was because of the power crisis that hit us post Aquino I admin... at that time... pupuwede daw sila mag generate ng electricity to sell outside.. however... they had a contract daw with Meralco... even if they use their own gensets.. they still have to pay Meralco (not sure ano yung technical basis.. baseload perhaps)... pero it was clear to me then that even if they have the capacity to do so, hindi pupuwede mag benta yung Nestle ng power to the area...

perhaps that was then... wala pa yung EPIRA noon...
