COMPARISON STUDY FOR COST OF POWER PRODUCTION

COMPARISON STUDY FOR COST OF POWER PRODUCTION

 

Solar Energy:

Assuming a solar panel site is installed at $900,000., and it operates at 10 to 15% efficiency.  Using the highest efficiency of 15%, an installed Megawatt of electrical output would be $6,000,000., per Megawatt of production.  The installation price is a low estimate and the output efficiency is a high estimate.  Solar panels use approximately 4 acres of valuable land per megawatt.

($900,000./15%=$6,000,000.)

The life expectancy appears to be 20 to 25 years, with an 80% production near the end of the life expectancy.  The efficiency when taken over one year could be less than 50% of the 15% efficiency, this would double the installation cost to $12,000,000., with a maintenance cost of 1% to 3% of the installation cost per year depending on location.  Therefore the depreciation of the installation will be between 5% and 8% of the installation costs per annum, or $300,000., to $480,000., per year.  Concentrators of solar rays to increase efficiency are known to kill or injure wildlife such as birds and insects, and are under scrutiny and subject to restrictions in California. 

 

Windmill Energy:

Assuming a windmill is installed at $2,000,000., and it operates at 34% to 37% efficiency.  Using the highest efficiency of 37%, an installed Megawatt of electrical output would be $5,405,405., per Megawatt of production.  The installation price is a low estimated installed price, and the output efficiency is a high estimate.   The decommissioning costs are expected to be $200,000., average, and operating and maintenance costs are extremely high.

($2,000,000./37%=$5,405,405.)

Wind turbines are known to kill and injure a substantial number of wildlife, such as large and small birds and bats every year.

 

GEM Turbine:

The GEM Turbine is installed at an estimated cost of approximately $1,500.000. to $2,000,000., per Megawatt of power output, site dependant. Low maintenance costs are due to the use of a limited number of 20 to 40 year environmentally friendly bearings with heavy metal components in the Turbine construction. 

The GEM Turbine will require new bearings every 20 to 25 years as per manufactures claims.  The easily accessed generators will require regular maintenance according to manufacturer specifications.  This results in very low operating and maintenance costs as the generators operate above the water.

The GEM Turbine has built in design protection to accommodate aquatic life and is environmentally friendly, with low noise pollution, slow speed, high torque, durable design.  GEM does not anticipate the mortality of any wildlife, but can produce substantial amounts of power due to its high efficiency.   The environment is paramount in the GEM Turbine design.
