The Hybrid Generator


The electricity market in Pakistan has been characterized in recent years by marked changes in the primary energy sources used for producing electricity. In the fiscal year 1990/91, hydropower still accounted for nearly 45% of all electricity generated in the country, but by 2001/2002 that share had dropped to only 26%. Simultaneously, the share of thermally generated electricity increased from 54% to 71%, most of that the increase is the result of capacity expansion since the early 1990s in response to power shortages and the resultant frequent power outages. Pakistan has little commercially exploitable oil of its own. Consequently, more than 55% of the country’s oil needs were met by imports in the fiscal year 2001/02, according to a report prepared by the Alternative Energy Development Board (AEDB) and Deutsche GesellschaftfürTechnischeZusammenarbeit (GTZ) GmbH

Though, Pakistan has fewer resources of fossil fuel but the use of fossil fuel in Pakistan is in the hike. It is used at various sectors including at local and residential sector and thus it is obvious that Pakistan is one of the lowest carbon producer countries in Asia but still, it is more affected and vulnerable to Climate Change effects. According to the report of the Global Climate Risk Index, Pakistan ranks fifth on global climate risk index.

Also, Pakistan has signed the Paris Agreement that emphasizes on to mitigate and limit CO2 emissions. The only way to decrease Carbon Dioxide and Green House Gas emission is to limit the use of fossil fuel.

With the advancements in technology and the volatility of worldwide the use of fuel and its prices, the production of energy from Renewable sources and battery-powered generators are on the rise.

A Hybrid Energy System may be defined as a system in which different energy sources (solar, wind, hydro, diesel generator, etc.), as well as energy storage systems, are interconnected to meet the load energy demand at any time. Given that the electrical contribution of energy, each source (taking individually) is dependent on the variation of the resources (sun, wind, water), and since the load energy requirement fluctuates, the main attribute of such a hybrid system is to be able to generate the energy at any time by optimally using each energy source, and storing excess energy for the later use in deficit generating conditions. The induced optimization problem is to compute the optimal size and operation control of the system with the aim of minimizing its initial, operation and maintenance as well as replacement costs while responding to the load energy requirements.

Principles of the Green Generator

A combination of a generator, movable solar panels and a battery pack ensures that energy is stored in the green generator so that the required energy can be provided at any moment, completely independent of the energy network and at any desired location.

The green generator is easy movable and positioning has the lowest fuel consumption and is functionally sustainable

The Green Factor

The most common and reliable way to utilize a hybrid generator is to combine it with a traditional diesel generator. Very much like a hybrid car, the generator acts primarily as a battery charger or power source when demand is higher, therefore greatly reducing the need for the diesel generator to be running. The reduction in the running time of the diesel generator reduces the emissions output of the generator over a course of a project. 

Hybrid generators may also be combined with renewable sources of a generator such as solar or wind to charge the battery. This could mean that in summer months or windy days, the generator is not required to charge the batteries at all, further reducing the project emissions. 
Case Study

To put the above in context, a customer of Power Electrics recently reduced their emissions by 24 tons when using a hybrid generator combined with a diesel generator over a period of 40 days. This is the emissions saving the equivalent of a small family car traveling 64,000 miles. 

 Along with the green credentials, a Hybrid Generator can reduce the amount of fuel used over a project, therefore reducing project fuel bills.

In summary, hybrid generators are able to provide dependable power which is emissions friendly, can reduce fuel bills, minimize noise on-site and provide a uninterrupted power supply.
