MTO Ocean Thermal Model_10 MW.xls

Ocean Thermal Energy Conversion or OTEC is most adapted in deep waters near the equator where the temperature difference between the surface (30 deg Celsius) and a depth of 1 km (10 deg Celsius) located within 10 km from the shoreline.

This 20 deg Celsius thermal gradient is available throughout the year near the equator and diminishes up to 40 deg North latitude and South latitude, beyond which the OTEC is not technically viable for having a much lower thermal gradient. This provides a very high capacity factor of 92% and it only unavailable when it de-couples during a tropical storm and the OTEC power barge transfers to a safer cove to ride the storm.

This MTO first-year tariff model for OTEC makes use of the basic assumptions of the country’s RE regulator for rated capacity (16 MW), capacity factor (92%), plant own use (36%), and transmission line loss (0.364%).

It assumes an overnight capital cost, fixed and variable O&M, spare parts replacement cost, substation and transmission line cost and distance, access road cost and distance, project development cost, 12% VAT, working capital and contingency. VAT recovery is 70% on the 5th year.

Construction period is 48 months while operating period is 20 years. Cost of capital is 16% p.a. for 30% equity and 10% p.a. for 70% debt.

Exchange rate is 44.00 PhP/US$.

Incentives provided by the RE Law is applied such as the 7 years income tax holiday, after which a 10% income tax is applied. Property tax of 1.5% applied on 80% of book value. Local business tax is 1% while DOE 1-94 contribution is 0.01 PhP/kWh.
