INTRODUCTION & BACKGROUND OF THE STUDY

A Diesel Power Plant (also known as Stand-By Power Station) uses a diesel engine as prime mover for the generation of electrical energy.

In engineering, a prime mover is an engine that converts fuel to useful work. In locomotives, the prime mover is thus the source of power for its propulsion. The term is generally used when discussing any locomotive powered by an internal combustion engine. The term is also applied to engine-generator sets, where the engine is termed the prime mover, as distinct from the generator.

In a diesel-mechanical locomotive, prime mover refers to the diesel engine that is mechanically coupled to the driving wheels (drivers). In a diesel-electric locomotive, prime mover refers to the diesel engine that rotates the main generator responsible for producing electricity to power the traction motors that are geared to the drivers. The prime mover can also be a gas turbine instead of a diesel engine. In either case, the generator, traction motors and interconnecting apparatus are considered to be the power transmission system and not part of the prime mover. An electric or battery-electric locomotive has no on-board prime mover, instead relying on an external power station.

This power station is generally compact and thus can be located where it is actually required. This kind of power station can be used to produce limited amounts of electrical energy. In most countries these power stations are used as emergency supply stations.

Operation

The diesel burns inside the engine and the combustion process moves a fluid that turns the engine shaft and drives the alternator. The alternator in turn, converts mechanical energy into electrical energy.

This type of electricity generating power station will probably be used a long time into the future, due to a need for reliable stand-by electrical source for emergency situations.

However, diesel power plants emit greenhouse gases that pollute the environment and also require frequent servicing.

DIESEL HISTORY

ORMECO CORPORATE BACKGROUND

Oriental Mindoro Electric Cooperative, Inc. (ORMECO) is non-stock, non-profit and service-oriented rural electric cooperative, duly organized under existing Philippine laws, rules and regulations. It was registered and incorporated with the National Electrification Administration (NEA) on February 16, 1973 covering six (6) municipalities in the northern part of Oriental Mindoro. The remaining nine (9) municipalities in the southern part of Oriental Mindoro were covered by the incorporation and registration of ORMECO II on July 15, 1977. On May 20, 1988 the two (2) coops were merged into what is now known as ORMECO.

After which the fourteen (14) municipalities and one city covered were re-districted into seven (7) districts. District 1 is composed of Baco, San Teodoro and Puerto Galera; District II is Calapan City; District III covers Naujan and Victoria; District IV consists of Socorro and Pola; District V comprises the towns of Pinamalayan and Gloria; District VI for Bansud and Bongabong; and District VII covers Roxas, Mansalay and Bulalacao. On June 26, 1988 ORMECO’s power plant was turned over to NAPOCOR in compliance with a memorandum of agreement executed by NEA, NAPOCOR and ORMECO.

POWER GENERATION AND DEVELOPMENT

At present, ORMECO sources its power from National Power Corporation, Global Business Power Corporation, (formerly MIRANT Philippines), and Dulangan Mini-Hydro Plant. A 25-MW Modular Unit, which is rented by NPC from AGRECO, supplies the main bulk of power supply needed by the province. Global Business Power Corporation (GBH) installed a 7.5 MW diesel power plant in Pinamalayan, Oriental Mindoro in order to provide reliable and efficient electric service in the southern portion of the province. Under the terms and conditions ORMECO buys power from GBH on a minimum off-take basis about 49 million kwh annually and ORMECO will pay a total fixed capacity fee and total energy fee plus cost adjustments arising from fluctuations in the price of bunker-C fuel and lube oil. As of the year 2006, 53% of the power requirement was supplied by NPC, 41% by GBH and 6% by the Dulangan Mini-Hydro Plant. With the increase in load of this booming province, we expect a great increase in power requirement within the ten (10) year period.

To this end, ORMECO continues its coordination and negotiation with different Independent Power Producers (IPP) to put up additional land based power plant on a short term basis and to invest on alternative sources of energy like wind and hydroelectric power for the long term power needs of the province. In so doing, the cooperative will be ensured of stable, reliable and affordable supply of electricity in the next years to come.
