As a Federal Installation, Fort Buchanan is subject to various regulations requiring energy conservation, to include:

Executive Orders, Energy Policy Act and Army Regulations for Energy Conservation /Facilities Management. These

Executive Orders established energy conservation goals to reduce consumption intensity by 40% total by the end of FY 2020

and 26% for water, through the end of FY 2020. Meanwhile, it also establishes Federal sustainability goals for the

reduction of greenhouse gas emissions (GHG) by increasing to 15% of renewable energy generation by FY2020 .

The Fort Buchanan Energy Conservation strategy seeks to support the mission by ensuring energy security and

modernizing its infrastructure while conserving energy and controlling utility costs whenever possible. The Federal Energy

Management Program (FEMP) designed thru the Energy Savings Performance Contracts (ESPC) a process to help federal

agencies improve energy efficiency in their facilities and reduce their energy costs, as mandated by the Energy Policy Act of

1992 and executive orders.

Wind Turbine Project 1. The Fort Buchanan ESPC project thru the proposed 10 Energy Conservation

Measures (ECMs), will install photovoltaic arrays, solar water heaters, water

conservation fixtures, lighting systems, high-efficiency ventilation and air

conditioning systems, building envelope improvements and wind turbines.

2. Wind Power Generation: This ECM installed two (2) GEV MP Wind Turbines

to reduce electricity purchased from the utility company with a renewable

emission-free source.

3. The GEV wind turbines will generate a Total Net Annual Energy Production

amount of 1 million kWh annually, an estimated annual savings of $178,500.00

in relation to electricity purchase actual costs.

4. GEV MP wind turbines are light, easy to transport and can be assembled by two

technicians without recourse to heavy lifting gear (cranes, etc.): only a telescopic

forklift truck is needed.

5. To facilitate the assembly and maintenance, or in the event of cyclonic alarm, the

GEV MP wind turbines can be easily lowered with the use of a tower measuring

55 meters high, thus canceling the risks of destruction of the

equipment.

Wind Turbine model GEV MP-32/275 specifications are: Hub Height; 55m (180’5”) tubular tower Rotor Diameter; 32m (105’) Rotor Rotation Speed; 2 speeds, 31 and 47rpm The GEV MP is two-bladed Materials of the blade, Glass fiber vinyl-ester resin composite Length of the blade; 15m (49’) Lowest point of the blade from the ground is 39m (127’)

Advantages of Wind Turbines

There are several advantages of wind power

generation on the basis of which it is oriented to

be the future of energy revolution. The most

prominent advantage of wind turbines is that they do not

pollute the environment as is the case by the use of carbon-

based fuels. Likewise, wind turbines do not generate

radioactive waste like nuclear power plants do. While the disadvantage of conventional sources of energy is

that they are exhaustible, wind energy is not subjected to any such problem. The cost is a factor that also works

in favor of this source of power as the investment incurred on development and operation of these turbines is

earned back within six to nine months of operation. More importantly, the raw material in this case, i.e. the

wind, comes absolutely free of cost and the only investment incurred is on development of infrastructure and

operation. Wind energy is certainly safe for humans as well as nature. No by-products are generated through

this form of electricity, therefore it does not contaminate the air, soil, or water resources in any possible

manner. This renewable source of electricity and energy does not require mining, or transportation, or other

unnecessary and wasteful resources in order to get the job done. In its place wind energy can be harnessed and

sent directly to the source of need, as long as the source is within the range of the turbine.

The Energy Policy Act of 2005 (EPACT 2005) and Executive Order 13423 direct Federal Agencies to

utilize renewable energy to the extent that it is both economically feasible and technically practicable to

offset current energy usage. Meanwhile, it also establishes Federal sustainability goals for the

reduction of greenhouse gas emissions (GHG). The Fort Buchanan Energy Conservation strategy seeks to

support the mission by ensuring energy security. The Federal Energy Management Program (FEMP)

designed, thru the Energy Savings Performance Contracts (ESPC), a process to help federal agencies

improve energy efficiency in their facilities and reduce their energy costs. The Fort Buchanan ESPC was

awarded in December 2011 and it eliminates the upfront cost to the Government, while it gets paid from

the savings generated by the incorporation of ten different Energy Conservation Measures (ECM),

including renewable energy and water conservation.

Fort Buchanan

The ESPC Energy Conservation Measure (ECM

10.1)enables the installation of ground, canopy and

roof mounted Photovoltaic (PV) electricity

generating systems with a maximum production of

renewable energy of approximately 6 Megawatt;

and involves the installation of 21,824 solar panels.

These projects support the Army's goal of

producing at least half (50%) of its utility energy

requirement from renewable energy sources by

2025. This power will be fed into the Garrison

power distribution system, which will offset

electricity purchased from the local utility company with renewable, emission-free,

solar energy. PV cells use semiconductor technology to convert sunlight into

electricity. This technology produces energy without producing pollutants or

greenhouse gas emissions that would, otherwise, be produced from fossil fuel burning

power generation facilities. With ample sunlight and high utility costs, Fort Buchanan

-Puerto Rico is a preferred location for solar energy.

Solar Photovoltaic principles Sunlight is composed of photons (discrete

units of light energy). When photons strike

a PV cell, some are absorbed by the semi-

conductor material and energy is transferred to electrons,

this is known as the Photovoltaic Effect. With their new-

found energy, the electrons can escape from their associat-

ed atoms and flow as

current in an electrical circuit. PV cells are the basic building

blocks of PV modules. They are made of semiconducting

materials (materials with the ability to conduct an electric current),

typically silicon and treated with special additives. Approximately

half a volt is generated by each silicon PV cell. When modules are

fixed together in a single mount, they are called a panel and when

two or more panels are used together, they are called an array. PV

arrays require no care other than occasional cleaning of the surfaces

if they become soiled, they must be kept clear of debris, and other

sources of shading to operate efficiently. PV cells are connected in series, so shading even one cell in

a module will appreciably decrease the output of the entire module.*
