INTERRUPTIBLE LOAD PROGRAM

ILP Implementation

4October 3, 2014

Process being finalized is to utilize stand-by generation of

contracted Contestable Customers to relieve system demand

duringYellow and Red Alert Situations

ACTIVITIES TO BE UNDERTAKEN

ILP Preparatory Activities

16October 3, 2014

� Confirm compensation rate approved by the ERC against embedded

generation costs

� Identify preferred operating hours and sustainable operating period

� Identify personnel to be contact point upon enrolment to ILP

Why Participate?

17October 3, 2014

� 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
