Demand-Side Management in Visayas: Why Another Route?
Wholesale Electricity Spot Market (WESM) proposed Visayas Supply Augmentation Auction (VSAA) Program which was approved by the Energy Regulatory Commission (ERC). The VSAA is aimed for demand-side management (DSM) in Visayas where interruptible load of embedded generators will be auctioned just like a competitive market. Please see approved proposed VSAA.
There have been reports that Visayan Electric Co. (Veco) has been practicing (DSM) by having interruptible contracts to its consumers. See this link: Veco, firms to sign power deal.
My question is this: Veco has a working DSM model system. Was there a study providing benefits of a market based DSM compared to the existing practice? Is there a need for a market based DSM that would add another fraction of peso to the rates being charged?
With ERC's approval, market based DSM will go through WESM instead of having Veco and its consumers taking directly. There might be added cost to that. You can say this is only Veco, how about the other distribution utilities? Well, the Veco model works as reported, why not adapt the model that works fine.

Demand Side Management in Visayas: Making It Work
As Visayas is having power problems, demand side management brings new opportunities to alleviate need for investments in new generation.
Inquirer reports...Ten major commercial establishments in Cebu let go of at least 174,847 kilowatt hours (kwH) of power from the local power grid over the past two weeks, allowing more electricity to be used by residences.
The “deloading” from the power grid was made by firms which relied on their own backup generators during periods of peak demand for electricity in Cebu.

Now You're Talking
The Institute of Integrated Electrical Engineers of the Philippines Inc.(IIEE), a group for local electrical engineers warned electric grid operator National Grid Corporation of the Philippines against employing foreign nationals as engineers to run the country’s power distribution network.

This is one concrete benefit of having a professional organization looking out for the welfare of its members. To IIEE, mabuhay!

Interruptible Load Application in the Philippines
Power drops 30 MW

A 30-megawatt (MW) power shortage last Tuesday forced a mall and hotel in Cebu City to rely on its own generator sets for one hour and reduce its demand on the Visayan Electric Co. (Veco). [ Read more ]

Philippines' Earth Hour: Success or Failure
One way to evaluate if the Earth Hour in the Philippines is successful or not is to compare the megawatt (MW) demand on March 21, 2009 and March 28, 2009. The Earth Hour was on March 28 at the time of 8:30 pm to 9:30 pm. We choose March 21 since this day is another Saturday which is the same as March 28. Inquirer reports that RP shone in dim during that hour. Philippine Star wrote that RP had record power savings during the event.
The facts say otherwise. The graph below describes the demand in Luzon and Visayas regions for March 21 and 28, 2009. The data were taken from Wholesale Electricity Spot Market (WESM) website. Comparing the demand curve of March 21 and 28 during the Earth Hour, we observed that there was more power utilization on March 28 than March 21. I am not sure where Inquirer and Philippine Star got their data.
