The Energy Regulatory Commission’s (ERC’s) approval of the application of GNPower Ltd. Co. for a retail electricity supplier’s license which was awarded on July 19, 2006 was marked as “another step forward” towards the full deregulation of Philippine power industry by introducing competition at the retail level.

Back when I was still working for the Senate Committee on Energy, it was around the early half of 2005. The issue on the sale of Masinloc Power Plant in Zambales exploded when the winning bidder, YNN Pacific Consortium, was found out to be under-capitalize, no experience in power industry, incorporated only around 4 months before the bidding, and according to Joker Arroyo then, to specific office (the company staying in the listed address in SEC was a manpower services office).

Amidst the rising cost of fuel in the world market and the implementation of EVAT that resulted to a tremendous increase of oil products such as gasoline, (http://philippineenergynews.blogspot.com/2006/05/oil-prices-up-by-p050.html), Energy Companies still have the opportunity to gain profit that is even more higher than the previous quarter of the year and getting higher and higher every year, while in contrast, the oil prices is also getting higher almost every less than a month.

Many thought that it is a loss for MERALCO if it gave-up its large consumers with a power consumption of 1 MW or more (and allow them to have a freedom to choose its own power supplier) since a big chunk of its consumers are industrial and commercial users which utilize power of more that 1 MW.

Last week, one of our clients sent us some questions about the output of our Distribution System Loss Segregator (A.K.A DSL Segregator), which currently, on the second stage of its development.
Here is one of their observation;
One of their feeders has around 1,800 KVAR of shunt capacitors installed in three parts of the primary distribution line. Initially, base on the output of the Segregator, energy losses at the primary line is around 460 Kwh. However, when they removed the capacitors, they noticed that the energy loss decreases to 390 Kwh. This is disturbing because the effect of that change is opposite to what should be expected, that is, increase the losses because the capacitor that was removed was intended to supply Kvar that helps in decreasing losses in the line. Thereby, according to them, removing capacitor compensation should go back into a higher loss system.
Does this mean that the DSL Segregation Software is inaccurate on its computation? Read the rest of this entry »

I’m wondering whether a capacitor compensation is an advisable option to improve the voltage security of a transmission system with continous power demand and supply fluctuations, especially for a radial system, with both dispersed synchronous generators and wind power plants.
