The document summarizes field trips taken to six different energy companies in the Philippines. Company 1, Trans Lift Port, manufactures and repairs ship equipment and uses DC welding. Company 2, One Subic Power, uses diesel generators which are expensive but flexible. Company 3, Benguet Electric Cooperative, provides power for Baguio and Benguet province. Company 4, Mirae Asia Power Corporation, is a 20 MW solar farm in Ilocos Norte. Company 5, Burgos and Bangui Windmill Farm, uses wind turbines with gearboxes and direct drive systems. Company 6, Agua Grande Hydropower Plant, was built in the 1970s but now only generates 1 MW for Pagudpud

3. COMPANY 1: TRANS LIFT PORT
 They are engaged in manufacturing, designing and repairing
ships equipment's.
 Always observed safety in the working area. Always wear
your personal protective equipment to avoid unnecessary
injuries and always follow the rules and guidelines of
operating the machines.
 Their DC arc welder is much better to used compared to AC
arc welder because the flow of current is strength or linear
while the ac is sinusoidal and as the result DC is more solid,
more strong and cleaner than AC.
 Other machines are energize by 440 ac voltage.

4. COMPANY 2: ONE SUBIC POWER
 They are using diesel as the source of energy. diesel
is more expensive compared to coal or any other
source of electricity and as a result the per KWh is
also expensive but aside from this disadvantage,
using diesel can also easily provide electricity
compared to coal because the coal takes time to heat
and generate.
 They used SCADA to monitor the level of diesel if it is
full or near to empty and also monitor the temperature
and operation of the whole system.
 The one Subic power plant is a reserved generation.
They can provide up to 116 MW of power that they
lend to NGCP for reservation in times of power
shortage.

5. COMPANY 3: BENGUET ELECTRIC COOPERATIVE
 Benguet electric cooperative deliver electric power to
the entire city of Baguio and Benguet province.
 They have two kinds of supply that is 220 V for the
standard voltage required by the NGCP and 110 V for the
old appliances and devices. Also they have connections
which are line to line and line two ground.
 They are the cheapest electric utility company in per
KWh.

6. COMPANY 4: MIRAE ASIA POWER CORPORATION
 The Mirae Asia Power Corporation started to operate in February
2016.
 The Mirae Asia Power Corporation is a solar generating company
that provides electricity in Ilocos Norte, it can generate up to 20
MW of power, 69 kV single circuit transmission line.
 Mirae Asia Power Corporation is a solar powered generation
company. It is composed of 20 array of solar panel connected in
series parallel connection. The solar panels can tilt up to 12
degrees. They are using polycrystalline type solar panel and it
consist of 64,800 solar panels all in all.
 Mirae power corp. used supervisory control and data acquisition
(SCADA) for monitoring the operation of the system. From solar
array it is connected to the array box generating dc power after that
it will pass through the Inverter and step-up transformer to become
ac power and produce 33 kV. Then to the MV Switchgear and step-
up transformer to produce 69 kV the to the transmission line.

7. COMPANY 5: BURGOS AND BANGUI WINDMILL FARM
 A windmill is a structure or machine that converts wind into
usable energy through the rotation of a wheel made up of
adjustable blades.
 The windmills in Burgos use gears to control its speed while in
Bangui they are using direct drive. In the nacelle of the windmill
you can see the generator, gear box if applicable and etc.
 From the time that the speed of the windmill reaches 3 m/s the
generator will start to produce electricity. If the speed of the
windmill reach 25 m/s it will stop automatically to avoid
damaged of the equipment. The transformer and converter are
located inside the body of the windmill and all the cables. The
windmill has the ability to locate the direction of the wind
because of the sensors that are place at the tip of the nacelle.
The windmill has the ability to tilt its blade to avoid damages
and to maximize the wind speed.

8. COMPANY 6: AGUA GRANDE HYDROPOWER PLANT
 Agus Grande Hydropower Plant is a mini hydro generating
plant that produce 4.5 MW of power which can supply 17,000
households in Pagudpud, bacarra and pasuquin during the time
of the former president Marcos at present time it only
generates 1 MW which is now suppling only the entire
Pagudpud. The power plant was constructed during the time of
former President Marcos.
