Case Study: synchronization of power generators - 2x 500kVA
What is the synchronization of power generators? You can read about it in the previous article. Now it's time to take a look at one of our recent projects related to the synchronization of power generators.
Problem: the generator set owned by the Investor generates too little electricity in relation to the current and forecasted production needs
Situation found: Volvo Penta 500 kVA generator set, current demand: 600 kW, development plans: 50% increase in production over the next 4 years
Investor's initial concept: to buy a new generator set with twice the power of the current one, sell a used VOLVO 500 kVA from 2013. (possibility of obtaining 40-50% of the price at which this generator was purchased)

It was assumed that the natural course of things is to replace old machines with new ones - newer, more efficient, working with more power (in this case: producing more power).
But nowadays, does the "replacement with new" generating set bring with it a higher economic and ecological value?
Let's assume, for the purposes of this article, that the Investor purchased a Volvo 500 kVA generator set in 2013 for PLN 120 thousand net with a small installation. At the moment, the Investor has the opportunity to sell this generator for approx. PLN 60 thousand. The current needs on the facility are 600 kW, however, forecasting rapid growth, the Investor wants to invest in a 1MW generator set. The current price of a 1MVA generator set is approx. EUR 100 thousand net, so significantly over PLN 400 thousand net. For the purposes of this article, let's take 460,000. Let's assume that it would cost 80,000 to install this genset along with an ATS system and a container enclosure or exhaust system at the generator room.
Let's assume that currently the generator set with the VOLVO 500 kVA engine costs PLN 150 thousand net. What percentage will the price of increasing the guaranteed power supply be reduced in the event that the Investor decides to synchronize?
Price of the generator set in case of replacement with a larger model: 460 - 60 (possible profit from the sale of a used generator set) = PLN 400 thousand net. Let's treat the price of the installation as a separate service.
Cost of the generator set: 120 (incurred in 2013) + 150 for the second same purchased in 2016 = PLN 270 thousand net. What is the price of installation and synchronization of power generators? Approximately it is the installation price of the 1 MVA generator set, without the costs related to the disassembly and transport of the used generator set. What percentage did the Investor save?
What economic and ecological benefits does the synchronization of power generators (aggregate-generator synchronization) bring to this target Customer?
Total cost is reduced by more than PLN 100 thousand in relation to the original plan.
The Investor plans to significantly increase production, and thus increase the demand for electricity. Further development of production will not disrupt the current energy plan and will not force the replacement of power generators. The synchronization cabinet designed and built by the PROtotypownia company can be freely expanded with another generator set (application of modular construction of synchronization cabinets).
The generator set and the ATS system have been adapted to the current needs of the production plant, so they do not require any personnel changes. Training in the operation of power generators and their synchronization was carried out at the price.
In case of lower demand for electricity, the Investor may, but does not have to, use both aggregates. Therefore, the ecological value of the solution increases (lower fuel consumption, lower consumption of machine parts, lower failure rate of power generators).
