ILP Mechanics in Meralco Area

ILP in MERALCO’s franchise area

1. Activated when NGCP issues a RED ALERT notice

2. Longer preparatory stage: Participants will be notified of possible activation even under YELLOW ALERT status

3. Initially for 1MW customers only.

4. “De-loaded kWh” will be based on the difference between an agreed baseline hourly load profile and actual hourly meter reading

5. Compensation for participating customers is the difference in rate between self gen rate and average Meralco rate.

6. Recovery of the compensation costs will be through the generation charge paid for by all customers in Meralco franchise as provided in approved ERC rules.

How you can help : sign-up to participate

Volunteer to de-load a certain amount of your demand

• Amount of your requirement that can be shifted to your generator

Choose a time slot

• Two options: 10am-1pm or 12nn-3pm

• Captures the peak demand that occurs from 12 noon to 2 pm

Agree on a baseline load profile

• As a reference for calculation of de-loaded energy

Designate 3 Contact persons

• Ensure proper communication and confirmation* at all times

* Basis for eligibility to compensation

Activation

16 May 2014 ILP Activation

• 8AM: Luzon grid on YELLOW ALERT based on NGCP advisory• Notified ILP participants of possible de-loading

• 1:25PM: NGCP announced RED ALERT from 1pm to 4PM due to the forced outage of Pagbilao 1 (375 MW deficiency)• Notified all ILP participants of de-loading from 2PM

to 4PM

• 2PM to 4PM: ILP activated• ~70 MW committed for de-loading from more than

50 establishments (e.g. malls, office buildings, etc.)

Activation

16 May 2014 ILP Activation

• Rotating Manual Load Dropping (MLD) had to be performed at 1:27PM to immediately restore system frequency in the grid

• Best effort for ILP was activation at 2PM

• Ensured continuous power supply to ~50,000 households

• Limited duration of rotating MLD

Compensation

Read

• Meralco Reads Meter

• Tags hours of ILP participation

Rate

• Determine Incremental de-loading rate

kWh

• Compare actual meter reading & baseline load profile

• Determine total de-loaded quantity for compensation

Pesos

• De-loading compensation = [Incremental de-loading rate x compensable kWh] + Maintenance Cost

Confirm

• Get customer confirmation and acceptance

• Customer issue invoice or statement of account

Pay & Receipt

• ILP participants receive compensation

• Customer issues receipt to MERALCO

Figures for compensation will be sent together with your bill

Compensation

Rule of thumb on De-Loading Compensation to ILP participant

• If an ILP participant de-loads 10 MW for 10 hours in a month, that participant will receive around ₱0.65 Million as De-loading Compensation

₱0.65 MillionDe-loading Compensation

=[₱6.3/kWh x 100,000 kWh]

Incremental De-loading Rate x

Compensable kWh

Compensation

Rule of thumb on the impact of recovering the De-Loading Compensation from end-users

• If 10 ILP customers de-load 10 MW for 10 hours in a month

• Add-on to the generation charge will be ₱0.0026/kWh

• ₱0.52 in the total bill of a residential customer consuming 200 kWh
