Optimal Load Dispatch Model for an Electricity Grid – linear programming (LP) model
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.

Model for Calculating Power Plant Emissions and outsourcing emission calculations
Calculating Power Plant Emissions for sale and outsourcing emission calculations
A spreadsheet model for calculating power plant emissions has been developed by your energy technology selection expert.
The calculation procedure is straight forward. The user inputs the ultimate (elemental) fuel analysis (%C, %H, %S, %O, %N, % moisture, % ash), excess air ratio (% excess air of % excess O2 in the flue gas) and a flue gas material balance will yield the wet and dry gas analysis of the flue gas (%CO2, % H2O, %SO2, %O2, %N2). Products of partial combustion (e.g. CO) and NOx (NO2, N2O) are not covered by this model since they are a factor of dissociation reactions and require complex equilibrium models.
If the fuel has substantial Sulfur and it needs to be removed (scrubber, limestone addition), the model will calculate the minimum sulfur removal efficiency that needs to be attained by the equipment to meet environmental standards (as %SO2, as ppm SO2, as mg SO2/normal cubic meter, as gram SO2 per kWh, etc).
Please email me your exact problem, input data and expected outputs to be calculated so I may be able to respond to your needs. The cost of the model and any customization works would have to be negotiated based on your specifications.

Feed-in Tariff Calculation Models for sale – biomass, cogen, mini-hydro, wind, solar and ocean thermal energy conversion (OTEC)
Feed-in Tariff Calculation Models for sale – biomass, cogen, mini-hydro, wind, solar and ocean thermal energy conversion (OTEC)
A project finance model for calculating feed-in tariff to be paid to renewable energy developers to recover their cost of capital, generation cost and provide for reasonable profit using the DCF IRR method has been prepared for the National Renewable Energy Board (NREB) of the Philippines.
Thus, given the renewable energy (RE) capacity expansion plan (capacity, generation), an estimate on the annual budget to be paid to RE developers could be prepared.
The FiT model calculates the first year tariff and the levelized selling price (tariff), levelized cost of energy and generation (LCOE), and levelized profit, which is similar to the proforma income statement presentation.
The user simply updates an input sheet to enter the case input data and converges the model by pressing a macro that will vary the first year tariff so that the interplay of revenue (FiT) less generation costs (fixed O&M, variable O&M, fuels and lubes, regulatory costs, depreciation, interest on loan) will result in an equity discounted cash flow internal rate of return (equity DCF IRR) equal to the minimum investor returns.
Interested consultants, regulators, project developers may request for demo (protected) excel copies for their appreciation of the inputs, calculation procedures, reports, graphics and summaries, and once they are convinced that it is useful, they may place an order at the ENERGY DATA page of this blog, and remit payment via PayPal for the desired model.
Alternatively, you may place an order via email and I will provide you with my bank details to remit the payment via wire transfer. Once confirmed that my PayPal or local bank account has received payment, I will then email two (2) excel (in xls format) file copies for your file.

Feed-in Tariff Models for Renewable Energy – biomass, cogen, mini-hydro, wind, solar and ocean thermal (OTEC)
Feed-in Tariff Models for Renewable Energy – biomass, cogen, mini-hydro, wind, solar and ocean thermal (OTEC)
Renewable energy feed-in tariffs for biomass, biomass cogen, mini-hydro or run-of-river hydro, wind, solar PV and ocean thermal energy conversion (OTEC) have been calculated using a project finance model prepared for the National Renewable Energy Board (NREB) by Marcial Ocampo – your favorite energy technology expert.
Using standard assumptions of supplier FOB, the all-in capital cost is calculated. The summary sheet of the model then summarizes the assumptions and results.

How to reduce electricity cost in the Philippines – response to latest MERALCO price increase
How to reduce electricity cost in the Philippines – response to latest MERALCO price increase
The largest distribution utility in the Philippines, MERALCO, recently reflected in the power bill of each residential, commercial, industrial, public building and street lighting consumer classification, the previous month’s rise in WESM prices.
I for one was also hard hit (my power bill increasing from P4,000 to over P7,900 last month), with the explanation of its MERALCO President, Mr. De Jesus, who said, the generation charge reflected the increase in the rise of WESM prices, the spot market of electricity producers. From a previous month of just over P5.14/kWh, the average WESM price jumped to over P6.70/kWh in view of the use of more expensive oil-fired power plants to replace hydro plant capacity that were temporarily lost as a result of a prolonged drought nationwide. Some plants are also undergoing preventive maintenance in preparation for the May 10 elections.
These events will not be the last, and will continue to persist, unless the country improves its generation mix. As I’ve said in previous blogs which was quoted by renowed Philippine Star Columnist Boo Chanco, “no amount of optimization of our existing generation mix will result in any substantial reduction in electricity tariff unless we introduce a significant quantity of nuclear electricity”.
The newly appointed Energy Secretary Ibazeta, who recently replaced Angelo Reyes, clearly emphasized to keep the nuclear power option open as a means to provide a long-term solution to the country’s high power cost.
The following blog will clearly illustrate the potential cost reduction with the entry of a 620mw nuclear power plant into the country’s generation mix, which will product electricity at a constant rate of around 2.50 Pesos per kWh.
Alternatively, the short-term solution is to construct more “clean technology” circulating fluidized bed (CFB) coal-fired power plants that is capable of generating electricity in the order of 50, 100, 200, 300 MW at costs far cheaper than oil-fired, natural gas-fired and geothermal power plants. As I’ve shared before, clean coal will be the transition fuel and power generation technology that will carry the world, including us, while we move towards renewable energy sources.
Happy Reading.
