The National Grid Corporation of the Philippines (NGCP), operator of the three main power grids of the country has declared in its website a negative 197 mw (-197 mw) system reserve for the Mindanao grid, this even after the huge 255 mw – Pulangi Hydroelectric Plant is back on stream last April 8, 2012. After all the hype about the full rehabilitation of Pulangi IV HEP, it appears that it did not change the power outlook for Mindanao. For how else could you possibly explain this? The National Power Corporation (NPC) has declared that Pulangi HEP can now generate its rated capacity of 255 mw during peak hours and together with NPC’s other power plants, including its IPPs, NPC can supply the Mindanao grid almost 1200 mw. Yet, NGCP in its website has declared only 1079 mw as system capacity. With a peak forecast demand of 1276, the Mindanao grid is short of 197 mw. These figures however raise more questions than answers.
First, when NGCP declares a system peak requirement of 1276 mw, does this already include the required 100 mw of contingency reserve? Is the 1276 mw the peak energy requirement of the grid or is already inclusive of the 100 mw contingency reserve? This is important because a declaration of load deficiency of 197 mw spells doom to consumers as this will result to a corresponding curtailment of the EC’s/DU’s contracted demand, forcing them to maximize its nomination of its TMI contract which will in turn cause our electric power bills to skyrocket!
It is my view that the 100 mw contingency reserve should not be factored in the determination of system peak requirement. It is just a reserve capacity that NGCP is mandated to secure by the Grid Code and does not actually represent as an energy requirement of the grid. Now, on the assumption that the 100 mw is included in the declaration of 1276 peak system requirement and we in fact take that away, total peak requirement will only be 1176, with a shortfall of only 97 mw. With lesser shortfall comes lesser TMI and therefore lesser cost!
Second, it is now high time to look into the nomination of NPC’s hydroelectric plants. Sources from NPC are saying that its power plants, including IPPs, can actually generate 1190 mw, enough to supply its contracted demand of 1186 mw and is also more than enough to supply the 1176 system peak requirement, assuming we take away the 100 mw contingency reserve requirement. And so, we ask: how much really of NPC’s 1190 declared capacity is actually dispatched, considering that NGCP is saying that system capacity is only 1079 mw? Is NPC over-stating its capacity? Is NGCP not dispatching enough of NPC’s declared capacity? These are the questions that I think the government and its regulators should look into. It would also be wise for electric power consumers and CSOs to work in concert and lobby for transparency. This is so because if NPC’s declared capacity is not maximized, then we are wasting millions of pesos worth of untapped capacity that simply goes down the drain, cascading down to the mouth of Agus river by way of unwanted spillage of water from NPC’s dams. And if not actually used, shouldn’t someone pay for the lost opportunity worth tens of millions per month? Simply look at the huge variance between NPCs declared capacity of 1190 mw and NGCP’s declared system capacity of 1079 mw. In term of its monetary value, how much is 111 mw lost opportunity per day?
Third, we already know that with Pulangi IV HEP back on the grid, the government’s generating capability will almost equal only its contracted demand. Unfortunately, the contracted demand does not actually address the total energy requirement of the ECs/DUs. Meaning, despite Pulangi IV’s rehabilitation, the electric cooperative’s actual demand is still un-answered to the tune of about 30% forcing it to nominate TMI. In the end, we consumers will still have to pay for the added cost from TMI’s expensive capacity; and woe to the ECs/DUs which do not have additional contracted capacity, e.g. ILPI.
In the case of ILPI which does not have any contract with TMI, it had not declared rotating brown-outs yet due to the assigned allocation from Treasure Steel. But when the assignment is done after one month, where will ILPI get additional capacity? When will its contracted MEGC capacity come on the stream?
Beg Iligan, beg.
When all else is said and done, it is still business as usual for the traditional electric power industry players, while, we, the consumers, bleed blood. Indignant.
