ILP Implementation De-loading Compensation De-loading Compensation=Incremental De-loading Rate × De-loaded kWh + Maintenance Cost ₱18,365 De-loading Compensation
=
(₱9.71/kWh x 1,831 kWh) Incremental De-loading Rate x De-loaded kWh
+
₱585.92 Maintenance Cost
Where: (₱43.26/L x 0.34 L/kWh) Generation Cost of Fuel x Fuel Consumption Rate Generation Cost of Fuel ₱9.71/kWh Incremental De-loading Rate

= =
Generation Cost of Fuel is the average price of diesel from Caltex, Petron & Shell the city or municipality where the ILP CC is located as of the end of the previous calendar month Fuel Consumption Rate is 0.34 L/kWh (2,305 kW – 474 kW) x 1 hour Baseline kW – Metered kW 1,831 kWh x ₱0.32/kWh or ₱23,548 per month, whichever is lower

Why Participate?
Shortage in 2015 will result to Automatic Load Drop (ALD) / Manual Load Drop (MLD) Scenarios for all those connected to the grid Enrolment to ILP will ensure prior notification for any ALD/MLD scenario during Yellow and Red Alert grid situations Operation of stand-by generation capacity will be compensated via ILP approved rate

IMPLEMENTATION ACTIVITIES
Implementation Activities
RESA, MERALCO and ERC discussions on-going for the implementation of ILP on the retail supply segment via re-declaration process of RES volume to MERALCO DOE support being provided to allow for re-declaration of RES volume in the WESM Review of tax applications on-going to determine possible assistance to be requested involving impact of ILP transactions to both the RES and participating ILP
