Simplified basic analysis and assumptions used to arrive at my figures. I am open to a challenge from anyone, who has not yet taken the time out to provide Jamaicans with some basis for the discussions regarding the 434 MW( not 360MW) plant being proposed by EWI.
LNG OPTION
| Installed Capacity (MW) | 434 |
| Rated output (MW) | 399.28 |
| Uptime /Utilization | 85% |
| # Days | 365 |
| Projected Run hrs | 7446 |
| Total Generated power (MWh) | 2,973,038.88 |
| Plant Rated Eff (CCGT) | 50% |
| Average Heat rate of LNG (MWH/m3) | 1.11E-02 |
| Total volume of LNG Req M3 | 537,160,924 |
| MMBTU of fuel required | 20,288,017.32 |
| Cost LNG US$/ (MMBTU) (Asia) | $ 15.00 |
| Total Fuel Cost /Annum | $ 304,320,260 |
| Fuel cost as a % of total cost | 85% |
| O&M Cost | 15% |
| Est total annual cost (Sub total) | $ 358,023,835.01 |
| Fuel Cost / KWH | $ 0.1024 |
| Total Cost per KWH | $ 0.1204 |
| Interest payment on loan | $46,423,767.88 |
| Total Annual Cost Incl Int Pay | $404,447,602.89 |
| Cost per Kwh | $0.1360 |
| EWI stated cost per KWH | $ 0.1456 |
| ROI > 6.6%( After tax) | 8.50% |
| Tax Rate | 33.30% |
| Total Generation Cost to meet After tax ROI | $497,985,833.77 |
| Sale Price to JPS (Minimum) | $ 0.1675 |
| Assumptions ( Best Guess) | |
| Plant Est Cost | $ 734,000,000 |
| Loan amount | $ 600,000,000 |
| Ave weighted cost of borrowing | 6.60% |
| Length of loan yrs | 30.00 |
| ROI > 6.6%( After tax) | 8.50% |
| Tax Rate | 33.30% |
Next I will look at the estimated pricing for electricity using HFO given this plant has dual fuel capability.
The $0.1675 represents the lowest possible price initial rate EWI would be able to sell electricity to JPS .
Missing from the analysis are the following
- The effect on inflation on the price of fuel
- The effect of the exchange rate on input cost
- Volatility of fuel price on world market.
- The effect of additional taxes by the GOJ
- Depreciation expenses.
- Time Value of money given this is a long-term capital-intensive project
- Other fees, legal, permit, EIA and other related cost.
This is just a basic analysis to try and get idea if the cost presented to us are a fair reflection of what it would actually cost to produce power , which would give a fair idea of how much savings the Jamaican consumer are likely to see.
