Basilan Strait Energy

From Philippines
Jump to navigation Jump to search
  • Author: Franklin H. Maletsky
Basilan Strait: Electric power generated from these power generators can power the provinces of Basilan, Sulu, Tawi-Tawi, Zamboanga City and even all of Mindanao and the Visayas islands.

The distance between The island of Basilan and Zamboanga City is approximately 24 kilometers. The seabed at the basilan strait is not that deep. Mostly only about 100 to 150 feet deep.

These Tidal or Sea Current generators can be installed at the sea bed of the Basilan strait. With floating (anchored) platforms to mark the location of the generators.

The platforms can also be built big enough to hold a standing windmill, rooftop solar panels, and enclosure for an OTEC system to generate electricity. These renewable source of energy installed in the Basilan strait can supply energy for the entire island of Mindanao, Sulu and Tawi-Tawi. Whenever additional energy is needed new platforms can be installed. Electricity can be even be supplied to islands in the Visayas region.

Without energy prosperity can't be achieved. Without prosperity there is no peace.


  • Zamboanga City: The city’s power requirement as of 2015 is 90MW but the supply (May 2015) reaches only 66MW leaving a deficit of 24MW which is equivalent to 6 hours rotational brownouts and blackouts daily.
    • SeaGen S 1.2MW system is capable of delivering up to 20MWh of electricity/energy per day. Installing two of these in the in the basilan straight will more that cover the differential.
    • The city depending on the budget can add as many systems as they want. Since there is no cost for the fuel to produce the electricity. It is all free and provided by nature.
    • 5 of these systems installed will make Zamboanga City independent from NAPOCOR. The city can actually graduate from being a consumer into being a supplier of electricity for the other nearby provinces by simply adding more systems.
  • Province of Basilan: by adding extra turbines in the basilan strait all the power needs of Basilan can be met. Even the far flung barangays will benefit from power generated from the sea.
  • One platform (4 combo) energy generators with a capacity of 3.5 Megawatt capacity will cost approximately 320M pesos as of 2016 costing. Building the 1500sqm platform with proper anchors will cost approximately 80 million pesos. The combined cost of of the generators and platform will be about 400 million pesos. Political elbow grease might drive up the cost a little bit, but it will be all worth it. A 3.5MG will produce about 60 MWh of electricity per day.
    • Two platforms will generate more than enough energy to help power Basilan and Zamboanga. New industries can be invited into the area and there would be no worry as to where the power will be coming from to energize these industries.

The city of Zamboanga and the province of Basilan can form a joint venture to create this "underwater power generators" and be the main supplier for the entire mindanao and even some islands of visayas. The fuel to power the generators is free (wind and sea current). The basilan strait is vast, therefore whenever extra generators are needed, there will always be room. Basilan and Zamboanga will then be able attract manufacturers and other industries to the area. The companies moving in do not have to worry about about buying backup generators. The sea current in the basilan strait is perpetual and strong.

One of the greatest plus will be that all the streets will be well lit at night giving the citizens an extra feeling of security.

Instead of relying too much on Diesel fuel and Coal to generate the majority of Philippine's Electrical energy Supply, we can concentrate more on renewable and sustainable source of energy such as: Hydro Power, Solar Power, and Wind Power and thermal energy conversion. We have too many black outs.

A tidal stream generator is also referred to as a tidal energy converter (TEC). A Tidal Energy Converter (TEC) is a machine that extracts energy from moving masses of water like rivers and seas. Energy can be extracted 24/7 non-stop.

The tidal stream generators can be located between the port of Zamboanga City and the two islands of Santa Cruz. These two islands are only 4 kilometers away from the port of Zamboanga City.

Or with the cooperation of governments of Zamboanga City and the province of Basilan the generators can be located behind the sta. cruz islands (between basilan island and the sta. cruz islands) away from future tourist traffic. The body of water between Zamboanga and Basilan is called the Basilan Strati.

Renewable Energy for Zamboanga City and the province of Basilan in the Basilan Strait

Tidal stream generators draw its power from sea currents, as much the same way as wind turbines gather energy from the wind.

The ideal place for the installation of this system is to put it within the Basilan Strait. Specifically between the Islands of Sta. Cruz of Zamboanga City and the island of Basilan.

The sea current that flows from the Sulu Sea (north) to the Celebes Sea (south) is strong enough to support the technology of the Tidal Stream Generators to produce sustainable electrical power for the City of Zamboanga, its neighboring provinces and the rest of Mindanao.

The distance between The island of Basilan and Zamboanga City is approximately 24 kilometers.

These Tidal or Sea Current generators can be installed at the sea bed of the Basilan strait. With floating (anchored) platforms to mark the location of the generators.

The platforms can also be built big enough to hold a standing windmill, rooftop solar panels, and enclosure for an OTEC system to generate electricity. Unlike dams or fossil fuel powered generators, the source of power for these windmills, solar, OTEC, and underwater turbines is unlimited. The water level of the dams can go down during drought and the price of fossil fuel is always fluctuating. The power from the wind and the sea is constant and free.

The local fishermen of the area who frequent the basilan strait say that the deepest part of the strait is about 70 meters deep. During the ice age this basilan strait was above sea-level.

A semi-submerssible type floating offshore wind turbine foundation call the WindFloat operating at rated capacity (2MW) approximately 5km offshore of Agucadoura, Portugal.
Locating wind farms out at sea can reduce visual pollution whilst providing better accommodation for fishing and shipping lanes. In addition, the wind is typically more consistent and stronger over the sea, due to the absence of topographic features that disrupt wind flow.

The best location for these floating energy farms will be between the Sta. Cruz Islands and the Basilan Island.

Energy can be extracted 24/7 without disruptions. There is no cost for fuel. Mother natures provides the fuel source for free.

Multiple energy producers can be utilized for every platform.

  • Bottom part will be the Sea current turbines.
  • The windmill can be installed on top of the platform.
  • Immediately below the windmills will be the solar panels which will also provide as a rooftop shelter for the platform.
  • Within the enclosed area of the platform will be the maintenance room and the generator for the OTEC (Ocean thermal Energy Conversion) system.
  • Each platform can be 1,500 square meters wide for stability and for housing capacity of OTEC, Solar panels and windmill.

This will be the first of its kind in the world. The combination of 4 systems and all utilizing renewable energy.

Power (Electricity) from: Verde Passage: Between the Main island Luzon and Mindoro

Located between the island of Lubang and the municipality of Calatagan, Batangas.

The same type of construction can be done at the Verde Passage. The combination of windmills and tidal generators. It will be environmental friendly and will not disturb the rich marine life at the verde passage.

The Verde passage is an excellent location because the distribution of electricity can be economically done for the Visayas and Luzon.

Enough electricity can be produced from this palo verde passage(strait) to supply most of Visayas and Luzon.

Renewable and Sustainable Energy

Renewable and Sustainable energy is the provision of energy such that it meets the needs of the present without compromising the ability of future generations to meet their needs.

The energy source will not be tapped out. As the future generation would be requiring more power to run their daily lives more generators can be installed. The energy output will depend entirely on the number of units installed.

Technology

The technology developed by MCT Marine Current Turbines works much the same as a submerged windmill, driven by the flow of water rather than air. Tidal flows are more predictable than air flows both in time and maximum velocity and it is therefore possible to bring designs closer to the theoretical maximum. The turbines have a patented feature by which they can take advantage of the reversal of flow every 6 hours and generate on both flow and ebb of the tide. The tips of the blades are well below the surface so will not be a danger to shipping or be vulnerable to storms.

Because the blades are relatively slow moving (15 rpm)and there are only two, it is considered unlikely that there will be adverse environmental impacts on fish or other aquatic life, and a monitoring project has been set up in the Strangford Lough project to confirm this.

Two approaches are being followed, one for relatively shallow waters, up to 30 metres (98 ft), and the other for deeper waters. In shallow waters, the turbines are suspended on a tower which extends above the surface of the water and enables the turbines to be lifted clear of the water for maintenance purposes. But since the number of sites around the world where this is possible is finite, they are also developing fully submersed systems which will take advantage of larger scale, but will also be able to be brought to the surface for maintenance.

How Electricity is Generated

Most of the electricity in North America is produced in steam turbines. A turbine converts the energy of a moving fluid (liquid or gas) to mechanical energy. Steam turbines have a series of blades mounted on a shaft against which steam is forced, thus rotating the shaft connected to the generator.

  • Coal, petroleum (oil), and natural gas are burned in large furnaces to heat water to make steam that pushes on the blades of a turbine. Coal is the largest single primary source of energy used to generate electricity in the North America.
  • Hydropower, the source of most electricity generated, consists of a process where flowing water is used to spin a turbine connected to a generator. There are two basic types of hydroelectric systems: one where flowing water from a reservoir is used, and the other the force of the water current applies pressure to the turbine blades.
  • Nuclear is a method in which steam is produced by heating water through a process called nuclear fission. When atoms of uranium fuel are hit by neutrons they fission (split), releasing heat and form a chain reaction releasing heat that spins a turbine to generate electricity.
  • Wind Power is derived from the conversion of the energy contained in wind into electricity. Wind power turbines are similar to a typical wind mill.

Currently there is only one technology that does not use turbines to generate electricity, that is Photovoltaics. Photovoltaics (PV) is a method of generating electrical power by converting solar radiation into direct current electricity using semiconductors that exhibit the photovoltaic effect. Photovoltaic power generation employs solar panels composed of a number of solar cells containing a photovoltaic material.

Materials presently used for photovoltaics include monocrystalline silicon, polycrystalline silicon, amorphous silicon, cadmium telluride, and copper indium gallium selenide/sulfide. Due to the increased demand for renewable energy sources, the manufacturing of solar cells and photovoltaic arrays has advanced considerably in recent years. Solar photovoltaics is a sustainable energy source.

How many homes can a megawatt power?

An average U.S. household uses about 10,000 kilowatt-hours (kWh)or 10MW of electricity each year. A watt is a unit of power, or energy per unit time, so it's the rate at which energy is being used. A kilowatt-hour (or 1000 watt-hours) is a unit of energy, so 10,000 kWh or 10MW is how much total energy each household uses over the course of a year.

This means that each household, on average, uses energy at a rate of about 1 kilowatt (1000 watts, which equal to ten 100-watt light bulbs).

One megawatt is equal to one million watts, so for one instant, one megawatt can power 1000 homes.

A better question to ask is how many homes can a megawatt-hour (MWh) provide with energy for one hour? If one home needs 1 kWh of energy for one hour, then 1 MWh of energy can sustain 1000 homes for one hour.

A 1 MW power plant produces 1000 kilowatts of power as long as it's operating at full capacity. So it produces 1000 kilowatt-hours of power each hour it operates, or 24,000 kilowatt-hours per day, or 8,670,000 kilowatt-hours per year (8,670MW).

To sustain 1000 homes, each consuming 10MW of electricity per year we need power plant than can produce 10,000MW per year. To properly sustain 1000 homes, one must operate a power plant with a capacity of 2MW.

Generation capacity often measured in Megawatts, or MWs, which refers to Millions of Watts. A Watt is a unit of power, referring to one joule per second (J/s) - the amount of energy generated in a second. A 100 MW power plant generates 100 million joules of electricity per second.

Generation capacity is also measured in Kilowatt-hours (kWh) which refers to the amount of energy used. A kWh is exactly 3.6 Megajoules - 3.6 million joules.[2] One watt-second is one joule. When an electric utility refers to electricity usage of X kWh per year, it means that the company's customers used X times 3.6 million joules of energy TOTAL for the year.

How much of our electricity is generated from renewable energy?
Last Updated: June 27, 2012
U.S. power plants used renewable energy sources — water (hydroelectric), wood, wind, organic waste, geothermal, and sun — to generate about 13% of our electricity in 2011.

Most Renewable-Generated Electricity is from Hydropower Renewable energy sources provided about 13% of total U.S. utility-scale electricity generation in 2011. The largest share of the renewable-generated electricity came from hydroelectric power (63%), followed by: wind (23%), biomass wood (7%), biomass waste (4%), geothermal (3%), and solar (<1%).

  • The United States Is Second in Renewable Electricity Generation

China leads the world in total electricity generation from renewable energy due to its recent massive additions to hydroelectric capacity, followed closely by the United States, Brazil, and Canada. However, the United States produces the most electricity from non-hydroelectric renewable sources; about 70% more than Germany, the next largest producer of non-hydro renewable electricity.

Energy Needs of the Philippines

Economical growth in any developing country depends on the availability of energy. This is true when it comes to the Philippines. Provinces and municipalities with not enough electrical supply do not develop as fast as those with readily accessible energy source. When electricity first came to the Philippines and generators were built all throughout the provinces, the people did not suffer from "blackouts".

But with the ample supply of electricity comes progress and development and progress generates more demand for electricity. Once the demand becomes greater than the supply, the power companies went into the "allocation mode" or simply blackout. Now (2013), the Philippines is suffering from this allocation.

To meet the need for energy from the citizens, the government in conjunction with private industries built several electric plants to generate electricity base on fossil fuel. The Philippines continues to import around half the coal and 75% of the oil it consumes to generate the power it needs.

The Philippine government is actively trying to entice local and foreign companies to invest in Energy. However, changes in policy and governance need to be made as pointed out in this report.

More government incentives are necessary to peak the investment interest of locals and foreigners. The government introduced the feed-in tariff (FIT) rates, however as mentioned in this report the f-i-t is not attractive enough.

FIT (Feed in Tariff)

SOURCE: http://www.erc.gov.ph/

Feed-in Tariff - Concept and Basis
Pursuant to the renewable energy development policy mandated by the RE Law and outlined in more detail in the FIT Rules, an RE Developer2, who (i) elects to participate in the Feed-in Tariff System, and (ii) meets the qualifications under the FIT Rules, and such other eligibility guidelines promulgated by the ERC (“FIT Eligible RE Developer” or “RE Developer”), shall be eligible to A Feed-in Tariff (“FIT”), which is a guaranteed payment in Philippine Peso per kilowatt-hour (“Php/kWh”) for emerging renewable energy it generates and actually delivers to the distribution and transmission network as metered at the high-voltage side of the step up transformer at the RE Plant3 side, excluding any generation for its own use, for a period of twenty (20) years from its Commercial Operation Date4 (“COD”), subject to the terms and conditions specified in the FIT Rules and clarified further by these Guidelines.

Should the payment of the FIT require a differential above the prevailing cost recovery rate for eligible RE Generation, then a uniform charge will be determined and collected from all grid connected consumers. This uniform charge shall be called the Feed-in Tariff Allowance (“FIT All”) and is described in more detail below. The FIT All shall approximate the total payments required to be made to all Eligible RE Developers under the Feed-in Tariff system based on forecasted values and shall be without prejudice to the actual entitlement of each RE Developer to receive the amounts payable to it for the actual energy delivered or exported to the relevant Grid under the Disbursement mechanism in Part 3 of these Guidelines (i.e., Actual FIT All Differential), as adjusted to ensure such payments are timely made, in accordance with these Guidelines. A basic schematic showing how the FIT All is collected from consumers and disbursed to eligible RE Developers is shown below.

Electric consumption of the Philippines

The rich and the big companies and off the grid barangays will benefit tremendously from Solar panels (photo voltaic). However, most Filipinos can't afford solar panels. They completely rely on the electrical grid. That is why the Ocean(sea) currents or tidal wave generators will benefit the majority of the population.

Most of the barangays in the Philippines are connected to the grid but with limited power. Tourist areas and Resorts use their own portable generators to generate power. With energy generated from the ocean the Philippines won't have to rely heavily on foreign oil for power.

Wind Energy

Currently we can only provide you with links:

Vertical axis wind turbines.jpg

GALE VERTICAL AXIS WIND TURBINE

The GALE™ line of vertical axis wind turbines has specific design considerations that make it a versatile and environmentally friendly product.

Some key benefits that have helped GALE™ blow past other wind turbine products:

  • Produces up to 50% more electricity on an annual basis versus conventional turbines with the same swept area
  • Generates electricity in winds as low as 4 mph (1.5 m/s) and continues to generate power in wind speeds up to 130 mph (60m/s) depending on the model
  • Withstands extreme weather such as frost, ice, sand, humidity and wind conditions greater than 130 mph (60 m/s)
  • Non-polluting through a sealed unit design with no gearbox
  • Easy on the eyes and ears being the only soundless wind turbine with non-reflecting surfaces to eliminate shadow strobing effect
  • Compact design reduces harm to wildlife - such as bird strikes

OTEC - Ocean thermal Energy Conversion

This plant is in Bataan Philippines. Originally designed to be a nuclear plant when construction started in 1976. The project was discontinued. This plant is an excellent candidate for the OTEC program.

Ocean Thermal Energy Conversion (OTEC) uses the temperature difference between cooler deep and warmer shallow or surface ocean waters to run a heat engine and produce useful work, usually in the form of electricity. However, the temperature differential is small and this impacts the economic feasibility of ocean thermal energy for electricity generation.

The most commonly used heat cycle for OTEC is the Rankine cycle using a low-pressure turbine. Systems may be either closed-cycle or open-cycle. Closed-cycle engines use working fluids that are typically thought of as refrigerants such as ammonia or R-134a. Open-cycle engines use vapour from the seawater itself as the working fluid.

OTEC can also supply quantities of cold water as a by-product. This can be used for air conditioning and refrigeration and the fertile deep ocean water can feed biological technologies. Another by-product is fresh water distilled from the sea. Demonstration plants were first constructed in the 1880s and continue to be built, but no large-scale commercial plants are in operation.


The bataan plant, which was in the process of commissioning at the time of the EDSA revolution, has not been fired, although nuclear fuel was delivered to it storage facilities. Maintenance has continued, with the integrity of the plant and ancillaries being ensured.

Background: The Bataan Nuclear Power Plant was completed in 1984, whilst construction commenced in 1976. It is a Westinghouse light water reactor, that uses pressurised water as it heat exchange medium between the reactor and the steam generators. Its design thermal capacity is 1876MW(t), whilst its rated power output is 621MW(e)1. The technology that is incorporated into the plant is essentially early seventies, but has been modified to incorporate more recent safety devices, such as those recommended by the US Nuclear Regulatory Commission, after evaluation of the Three Mile Island incident.

The Philippine government made feasibility studies to convert this plant into fossil fueled generator but all the plans failed.

I think OTEC will work for this plant. it will not be as costly as fossil fueled plants.

Biomass Turbine Generators

Biomass is the organic matter produced by plants. Also it refers to other organic wastes like animal waste, food-processing by-products etc. Everything that is biodegradable is biomass. The solar energy trapped by these plants can be converted to electricity or fuel.


Biomass Steam Turbines from GE

Here is what GE is marketing:

Biomass Steam Turbines

To help customers reduce carbon emissions and improve fossil plant cycle efficiency, while meeting Renewable Portfolio Standard(RPS) targets, GE developed a line of biomass steam turbines that provide high performance with a small footprint. GE's biomass steam turbine product line offers a compact, high efficiency solution for the 60 Hz and 50 Hz markets that offer a wide range of footprint and efficiency options for ratings up to 250 MW.

Giant King Grass is suitable as a fuel for direct combustion (burning) in 100% biomass electricity-generating power plants. Today, biomass power plants are fueled by agricultural and forestry waste such as corn stover, wheat straw, rice husks and wood waste. The price of agricultural waste has increased dramatically in China and India due to market demand, and in many areas, growing Giant King Grass as a dedicated energy crop is less expensive and more reliable than using waste. Agricultural waste is seasonal, because it is only available after the food crop such as corn is harvested. The corn stover must be gathered over long distances because the yield is quite low, then dried, baled, stored and utilized as fuel until the next agricultural waste crop is available. Reliability, consistency and cost of biomass fuel are the major issues facing biomass power plants today. A dedicated Giant King Grass plantation co-located with a power plant is a cost effective and reliable solution to producing clean electricity.>>Read More

A more detailed description of biomass turbines:

Cogon Grass can be used as a replacement fuel for this type of generator. Cogon Grass just as Giant King Grass is renewable.

Biogas generator from biomass

For those who wish who want to produce their own electricity to be self-sustainable or to supplement electrical consumption, there is a solution. You can build your own biogas generator. The fuel to power this generator is readily available. The grass clippings, food waste livestock manure, or any organic waste can be transformed into renewable biogas energy.

Cogon and Grass used for Biogas Generator to Produce Natural Gas

As cogon and grass decompose, methane and carbon dioxide are created. The methane produced can be captured and stored via various types of containers. Biogas is flammable gas and is composed mostly pf methane and carbon dioxide, which are formed when organic materials decomposes anaerobically. This method of producing biogas helps reduce global warming and pollution.

How many homes can a megawatt power?

An average U.S. household uses about 10,000 kilowatt-hours (kWh) of electricity each year. A watt is a unit of power, or energy per unit time, so it's the rate at which energy is being used. A kilowatt-hour (or 1000 watt-hours) is a unit of energy, so 10,000 kWh is how much total energy each household uses over the course of a year.

This means that each household, on average per hour, uses energy at a rate of about 1 kilowatt (1000 watts, which equal to ten 100-watt light bulbs).

One megawatt is equal to one million watts, so for one instant, one megawatt can power 1000 homes.

A better question to ask is how many homes can a megawatt-hour (MWh) provide with energy for one hour? If one home needs 1 kWh of energy for one hour, then 1 MWh of energy can sustain 1000 homes for one hour.
