How to use the advanced (regulator) petcoke-fired SUBCRITICAL power plant project finance model
Finding an easy-to-use project finance model for a petcoke-fired SUBCRITICAL power plant with built-in data is sometimes difficult as some models don’t have the sophistication of a regulator template model as well as the ease of using the model and viewing immediately the results of a sensitivity change in the inputs to the model.
This is now made easy because the Input & Assumptions worksheet (tab) has combined all the input and output information in a single worksheet and placing the reports in other worksheets such as Tariff Breakdown, Construction Period, Operating Period, Financial Reports and Levelized Tariff.
Following is a sample case study on a petcoke-fired SUBCRITICAL power plant. From the preliminary design and cost estimates, the top management would want to know if the business idea of going into petcoke-fired SUBCRITICAL power development, construction and operation is worth the effort – is it feasible and what are the economic and financial returns for risking capital.
Here are the inputs and outputs of the advanced template model from OMT ENERGY ENTERPRISES:
Here are the summary of inputs:
all-in capital cost (overnight cost) = 3,000 $/kW (target cost)
EPC cost portion = 2,034 $/kW (computed by model)
refurbishment cost = 5% of EPC cost on the 10th year (overhaul)
fixed O&M cost = 37.80 $/kW/year (target cost) = 3,452.00 ‘000$/unit/year (computed by goal seek)
variable O&M cost = 4.47 $/MWh (target cost) = 30.26 ‘000$/MW/year (computed by goal seek)
general admin cost = 311.00 ‘000$/year (target cost)
Thermal power plant inputs:
Gross heating value of petcoke fuel = 14,670 Btu/lb
Plant heat rate = 8,800 Btu/kWh (38.77% thermal efficiency)

Weighted Average Cost of Capital:
WACC = 10.80% p.a.
WACC pre-tax = 12.43% p.a.
WACC after-tax = 8.70% p.a.
Results of Financial Analysis:
First year tariff (Feed-in-Tariff) = 6.16152 P/kWh = 0.12250 USD/kWh
(at zero equity NPV)
Short run marginal cost (SRMC) and Long run marginal cost (LRMC):
SRMC = 1.77044 PHP/kWh (variable O&M + fuel + lubes)
LRMC = 6.16152 PHP/kWh (capital cost + fixed O&M + regulatory + SRMC)
Equity Returns: (30% equity, 70% debt)
IRR = 15.00 % p.a. (target returns)
NPV = 0.00 ‘000$
PAYBACK = 8.66 years
Project Returns: (100% equity, 0% debt)
IRR = 12.09 % p.a.
NPV = (2,424,999) ‘000$ (negative since IRR < 15.00%)
PAYBACK = 6.78 years
The above runs were based on goal-seek to make equity NPV = 0 (to meet equity IRR target of 15.00% p.a.).
You can perform sensitivity analysis and save the results in a case column (copy paste value).
You can breakdown the tariff ($/kWh) into its capital ($/kW-month) and variable cost recovery ($/kWh) portions.
You can prepare all-in capital cost breakdown showing interest cost during construction and does model the impact of project construction delays.
You can show the evolution of capacity and generation (degradation) during the operating period and show other revenues, expenses and balance sheet accounts as they change over time during operation years.
You can show the income & expense statement.
You can show the cash flow statement.
You can show the balance sheet.
You can show the debt service cover ratio (DSCR) as it computes the cash flow available for debt service.
It also computes the benefits to cost ratio (B/C) of the project.
Finally, it computes the other financial ratios such as:
