New Simplified Calculation Procedure for Levelized Cost of Energy (LCOE) and Feed-in Tariff

New Simplified Calculation Procedure for Levelized Cost of Energy (LCOE) and Feed-in Tariff

As part of the on-going technical preparations for the proposed mini-conference on the Mindanao Power Crisis this coming late August or early September 2010 and the main conference on “Energy & Climate Change”, the workshop coordinator, Mr. Marcial T. Ocampo, has prepared the simplified calculation procedure for calculating the levelized cost of energy (LCOE) and levelized selling price (tariff) for conventional and renewable energy resources.

The result of the simplified formulas using the US NREL formula for generation cost and the RP MTO formula for selling price were compared with the results from a full-blown project finance model and the variance between the two methods were minimal in most of the power generation technologies analyzed.

The input data came from the IEPR research summary of 2007 and from internationally published data on power generation technology by noted experts such as Paul Breeze and yours truly, Marcial Ocampo. More »

How to calculate overall thermal efficiency of combined cycle power plants – a sample CCGT presented

Calculating or predicting the overall performance of a combined cycle power plant, specifically a combined cycle gas turbine (CCGT) power plant is sometimes difficult for most design engineers. Your favorite energy technology expert again comes to the rescue – Engineer Marcial T. Ocampo – has derived the following equation to guide the design engineer and project finance modeler or business development engineer in predicting the overall thermal efficiency of the combined cycle.

Combined Cycle GT (CCGT)

GTs have at best efficiencies from 35% to 42%. Almost 60% of the fuel energy is wasted in the turbine exhaust of a GT. Capturing this waste heat in a heat recovery steam generator (HRSG) is the basis of the combined cycle (Brayton + Rankine). The HRSG produces steam that drives a turbo-generator to produce additional power.

Topics – Combined Cycle GT

• Operating Principle of a Combined Cycle GT
• Combined Brayton + Rankine Cycles
• Comparison of Various CCGT Configurations
• CCGT (Gas vs Liquid Firing)
• CCGT Energy Balance
• Examples of Gas Turbine Technologies
• Cost of GT Technologies
• GT and CCGT Plants in the Philippines
• Advantages, Disadvantages of CCGT
• Environmental Impact, Risks of CCGT
