Differentiating Single Versus Parallel Generator

A business needs an uninterrupted power supply and they usually depend on the generators for their power needs. There are two ways of getting the generator connected. There are many factors which a business needs to consider while making a purchase decision. Here are the factors which needs to be considered while making the choice of generator –

Reliability Issues

There are certain businesses which can’t afford to lose power even for a second. For example, hospitals can’t function without power as this would put the patients at risk. In such a case, the organization should opt for parallel generators as a failure of one generator would not impact the operations. Data Centres should also rely on Parallel Generators.

Cost Effective

Cost is a major concerned for the organizations as today our business is driven by Cost. As a matter of fact, it is very expensive to operate Parallel Generator and at the same time, the initial set up cost for parallel generators is very high. Along with this, maintenance cost for the parallel generators also touches the sky. Set up cost needs be equated with the cost of downtime in case of single generator failure and the decision should be based on the trade-off between cost and benefit

Performance Issues

If your business has high load requirements then it is better to go for Parallel Generators as the load can easily be distributed between the two generators without impacting the power factor of the transmission. Whereas Single Generators are sufficient if the business doesn’t have heavy machinery.

Expansion Plans

If the business is expected to expand in coming years then it is advisable to install parallel generators because it is difficult to install more generators in Single Generation system whereas it is much easier to add more generators to a parallel system.

Deviation in Load

If there is a large deviation in load then it is advisable to go for Parallel generators because of chances of failure of the single generator increase with variability in the load. It is possible to manage with a single generator if the machines do not put a heavy load on the generator. But the decision again needs to be mapped with the reliability issues.

Size of Generator and Space

This is another factor which decides the configuration of the generator. If your organization have space constraints then it would not be possible for you to install multiple generators. Hence in such a case, the only single generator would be an option for you.

Efficiency of Operations

This is another issue that comes into the picture while making a decision of installation of generators. Usually, parallel generators would be less efficient than a single generator as the fuel consumption will increase dramatically in the case of parallel generators. This could impact the profitability of business to a great extent hence operational cost should also be considered while making a purchase decision.

These were some of the factors which need to be considered before making a final decision about the configuration of generators.
