How to use the advanced (regulator) ocean current and tidal current power plant project finance model

(Lord God, bless my website and my readers that they will contribute to my charity fund for the jobless, sickly, needy, homeless, hungry and destitute. God Bless you all my friends for reading my blog and ordering my project finance models. Amen.)

Finding an easy-to-use project finance model for an ocean current and tidal current 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 tidal current power plant. From the preliminary design and cost estimates, the top management would want to know if the business idea of going into tidal current 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) = 2,473 $/kW (target cost)

EPC cost portion = 1,112 $/kW (computed by model)

refurbishment cost = 5% of EPC cost on the 10th year (overhaul)

fixed O&M cost = 86.19 $/kW/year (target cost) = 203.36 ‘000$/unit/year (computed by goal seek)

variable O&M cost = 2.40 $/MWh (target cost) = 15.89 ‘000$/MW/year (computed by goal seek)

general admin cost = 500.00 ‘000$/year (target cost)


Thermal power plant inputs: (not used in tidal current)

Gross heating value of tidal current fuel = 5,198 Btu/lb

Plant heat rate = 13,500 Btu/kWh (25.28% thermal efficiency)

Cost of tidal current fuel = 1.299 PhP/kg = 1,299 PhP/MT


Lube oil consumption rate = 5.4 gram/kWh

Density of lube oil = 0.980 kg/Liter

Cost of lube oil = 200.00 PhP/Liter

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:
