Mindanao grid which is dominantly
being populated with coal plants is now bracing for immediate energy mix
rebalancing – with the aid of government and industry players.
In the assessment of Joseph C. Nocos,
vice president for business development of Alsons Energy Development
Corporation, rebalancing the grid’s energy mix must be set “against the
backdrop of the load profile.”
As reckoned on estimated peak demand
of the system or grid, requirement for baseload shall be set at more or less
50-percent; then mid-merit shall account for 30-percent; and 20-percent shall
be allotted for peaking capacity.
And taking off from that, he said
that the other critical step would be “to see what technology is appropriate
for that type of a mix.”
Nocos opined “whatever the load
profile dictates should also be influenced by the ratio among coal, gas and
renewable energy plus we also have to consider what is already in place.”
He stressed that it is also
paramount to factor in as to “how long it would take for the market to absorb
or digest all of the existing capacities.”
For Mindanao grid, in particular,
Nocos noted that the ideal mix would be to have a baseload that would be
between 50-percent to 65-percent.
“The Agus plants will continue to
provide capacity and energy to the grid, mid-merit as well will be
well-provided in Mindanao,” he said.
Nocos expounded “given the
preponderance of coal capacity that we expect to have in the next 2-3 years, I
think our baseload requirement would be well-provided for.”
For peaking supply, he noted that
diesel plants will continually soak up that function in the system – even when
Mindanao has already achieved fully its power supply solutions.
