Why Philippine Electricity Reserves are always not adequate?
This is a question perennially asked by ordinary citizens, businessmen, investors, and now legislators. It is happening as if no one is minding the store.
Well, I have some ideas that will open our eyes on the real score.
We lack power reserves, the difference between peak demand and dependable capacity. The key word is dependable capacity, and not installed capacity.
Adequate power reserves are needed so that in the event that the largest single unit in the grid goes off-line, these back-up power reserves kick in with sufficient ramp-up rate to prop-up the supply immediately so that the grid remains stable and does not go into load-dropping mode to equalize supply with demand.

Short-Term and Long-Term Solution to the Mindanao Power Crisis
Mindanao needs temporarily for the next 5 years turbo-charged high-efficiency diesel genset units (4 x 50mw) in a power barge configuration. While it may appear expensive on a per kwh basis, it is operated only when there is a power deficiency, and its cost will be due to capacity fees (to recover capital costs for its 5-year deployment), operating & maintenance fees (to recover manpower, spare parts and admin fees) and fuel costs (pass thru fuel conversion costs).

Recent Orders from our Readers: Optimal Load Dispatch (LP) and Power Plant Emission Models
Your energy technology selection and business development expert/consultant would like to inform our other readers that a kind reader has donated and purchased my Optimal Load Dispatch (Linear Programming or LP model) that could be solved using the Solver tools built-in with MS Excel.
Likewise, I receive an urgent inquiry and interest on how to calculate power plant emissions: mass emission (kg/hr, lb/hr, tons/hr) and volume/mass concentrations (% volume, ppm volume, mg per normal cubic meter or mg/Nm3). More »
Optimal Load Dispatch Model for an Electricity Grid – linear programming (LP) model
An optimal load dispatch model for the Luzon, Visayas and Mindano island grids of the Philippines has been prepared by your energy technology selection and business development expert.
Using linear programming techniques, an optimal load dispatch problem has been prepared in an excel spreadsheet (xls format) which the user can modify and expand and update input data for his particular electricity grid to be analyzed.
This model is a must for regulators in order that future capacity expansion studies are optimized to minimize generation cost and therefore the cost of electricity. Power plant developers and investors will likewise benefit from this model in order that estimates as to the desirability of a new capacity investment will be made at the drawing board before the actual power plant is constructed. It will provide estimates on the level of dispatch a new power plant will expect given the existing power generation mix and incremental (variable) O&M costs.
