Dereating: how Temperature and Elevation Affect Generators

/0 Comments/in , /by

Testing a generator derating ambient temperature

In certain environmental conditions, generators can suffer power losses. Preventing these will allow us to ensure the maximum efficiency of our equipment.

All engines and alternators are capable of offering 100% capacity when they operate in standard or not so demanding environmental conditions, but when they must function in environments with high ambient temperature or at a high elevation or altitude above sea level, their capacities may be reduced.

The engine manufacturers, for instance, usually guarantee a certain performance provided that some values are not exceeded (generally a temperature of 25ºC and 1000 m above sea level). If these values are exceeded, the user has to bear in mind that, very likely, the engine will not perform at its top capacity.

This loss of power in function of temperature and elevation is known as derating, and is something which has to be very much taken into account when it comes to sizing a generator.

 Generator dereating factor in conditions of altitude

Just as it happens to us human beings as we climb higher above sea level, the lack of oxygen and the low pressure affect the performance of the generator.

Elevation affects all kinds of engines, but this effect is more prevalent in atmospheric engines, which depend upon atmospheric pressure for the air to reach the cylinders adequately.  These losses of power may even occur at elevations below 1000 meters.

In the case of turbo engines, the turbine is capable of countering this air deficit. Therefore, generally, the power derating of this type of engines starts to occur at an elevation of 1000 meters above sea level and its effect is inferior to that affecting atmospheric engines.

The alternator also suffers at a higher elevation, given that with less air it tends to overheat. In general, the majority of manufacturers guarantee that the alternators will not lose power until reaching 1000 meters above sea level. At higher values, the average loss of power is generally of 3% for 500 m of elevation.

Generator performance at high temperatures

Generally, temperature affects generator engines starting at 40ºC. Above this ambient temperature: 

  • The air is already very hot and its quality is no longer optimal to generate good combustion when mixed with fuel. This generates loss of power.
  • The fuel may reach the engine at an excessive temperature, and combustion will not take place in adequate conditions. 
  • The efficiency of the cooling system will be diminished. As a result, if the radiator is not correctly sized, the generator can stop functioning due to an excessive water temperature. 

Generator derating ambient temperature

As far as the alternator is concerned, it is also affected by high temperatures. The majority of manufacturers guarantee the power of their alternators, as long as they operate at an ambient temperature of below 40°C. At higher values, the derating in an alternator is generally of 3% for each additional 5º C.

The importance of having foresight

Given all of the above, when sizing a generator, it is crucial to have a clear understanding of the environmental conditions under which it will operate, i.e.: the inferior and superior limits of ambient temperature and barometric pressure in the setting-up location, as well as the elevation above sea level at which the equipment will be located. 

With this clear information provided, we, the engineers, shall be able to foresee and counter the effects of power derating, selecting the most adequate engines and alternators for each equipment.

If your project will be carried out in extraordinary environmental conditions, we at GENESAL ENERGY can advise you and size your generator in such a way that your ideas never lack power.

/0 Comments/in , /by
The company expands its headquarters by 3,000 square meters in order to increase its production capacity.

Genesal consolida su crecimiento en 2019

Genesal Energy consolidates its growth in order to tackle a 2020 full of projects in Spain and in the demanding international market

The company continues its international expansion in strategic sectors and countries with personalized customer service as well as services like the Technical Assistance Service

Power plants, electric substations, DPCs, hospitals, airports, food and telecommunication sectors. Genesal Energy is present in all of these industries thanks to the versatility and high specialization of its equipment. With more than 25 years’ experience (this year the Galician company celebrates its anniversary) and with branch offices in Mexico and Peru, the company is closing 2019 with constant and controlled growth and with its mind on a new year full of projects. Because Genesal Energy’s objective is to continue growing internationally with a presence in new markets like the Asian giant Taiwan, but also nationally by increasing its production capacity with new installations adding up to 3,300 square meters at its central headquarters in Bergondo (province of A Coruña).

Here are some success stories and challenges for the future.

New rental product lines:

The search for new lines of business within an increasingly competitive market is one of Genesal’s commitments, and the rental line, with some excellent results at the end of the first year of its launch by the company is an excellent example. Reliability and robustness define these gensets destined for the rental market. Following the success of this product line and the official presentation in Mexico, where four generators were subsequently delivered, the company will continue its commitment to these rental products throughout the 2020 fiscal year. They are special products, custom made so as to make maintenance easier, and fitted with state of the art GPS systems for their immediate geolocation in case of theft.

Emergency energy for large health centers: Toledo Hospital (Spain) and Montero Hospital (Bolivia)

Electricity is vital in hospitals and its absence can have fatal consequences, which is why it is necessary to have state-of-the-art emergency generator systems. Among the projects carried out by Genesal in 2019, a special mention should be given to the supplying of four generators to the new hospital in Toledo which will open in the first semester of the year. They are four generators of 2250 and 2500 kVA which will function in parallel. Outside Spain, Genesal Energy offers a turnkey service to Montero Hospital (Bolivia): three 410-450 kVA generators, which are soundproof, one of them automatic, the other two in parallel with the air outlet on the upper side in order to fit in with the installation.

Gaining ground in the wind energy sector: from Los Llanos to Monte Cristi

This year Genesal has strengthened its presence in the field of renewable energy with a good number of wind farms in its portfolio. For example, in 2019, the company supplied emergency equipment for the substations in Oriche and Venta Vieja, in the province of Teruel, Montilla del Palancar (province of Cuenca) and in Serra das Penas (province of Lugo), and also for the wind farm in Los Llanos (province of Málaga), an installation for which we manufactured and delivered turnkey equipment. Internationally, we delivered a 100% personalized generator for the wind farm in Monte Cristi (Dominican Republic), whereas for the Agua Clara wind farm on the same Caribbean island, Genesal’s Engineering Department designed and manufactured a hurricane-proof generator for the whole park, which has 25 air generators, supplying power for 250,000 persons.

Biomass plants: the Viseu and Fundão stations

In Portugal there are two stations considered prime examples in the production of clean and renewable energy. They are the biomass plants located in Viseu and Fundão, repectively. Genesal installed special tailor-made equipment in both of these facilities.

More projects in Mexico: the combined-cycle power facility Topolobampo III

Genesal Energy’s strong presence in Mexico results in numerous projects, some of which are on a very large scale. Such is the case of the Topolobampo III combined-cycle power facility, whose founding in the municipality of Ahome was encouraged by the Mexican Federal Electricity Commission (CFE), and which will supply power to more than 2.5 million people. It will start operating in 2020 and the emergency power for it will be supplied by Genesal.

Tailor-made generators for the Saudi Embassy in Chad

The embassy of Saudi Arabia in Chad also uses emergency power from this Spanish brand. Concretely, the order consisted of three sets of tailor-made generators of two different powers: of 2 x 1.000/1.100 (ojo, en español, también está mal, sobra un 0) kVA, 2 x 1.500/1.650 kVA and 2 x 25-27 kVA respectively, supposed to work in parallel.

Bigger presence in Asia: entry into Taiwan

The growth witnessed in Southeast Asia over the last two years was strengthened in 2019 with the addition of a new market: Taiwan. Said country is one of the most powerful economies in the world and Genesal entered its market through several projects. In total, we have supplied the Government 13 generators. It’s our aim to continue to expand the market with new operations.

New year, new challenges

The good results obtained in the 2019 fiscal year, which has seen a constant growth, induces optimism once again. The company, after 25 years of presence in the energy sector, has now grown up and expanded its central installations in Bergondo (province of A Coruña) by 3000 square meters. The new space is meant to provide the necessary production capacity in order to tackle the new challenges by an orderly growth, given that Genesal Energy’s main aim is always the customer, who should never feel unsupported, the company states.

An example of this commitment to close attention and personalized projects -a hallmark of our company- is the boost received by the Technical Assistance Service (SAT) Department -now an indisputable benchmark in matters of remote management and multi-branding- a section which is closing the year with a steady growth and the modernization of its vehicle fleet, a process which takes into account the latest developments in ergonomics.

As far as the expansion plans are concerned, Genesal Energy will maintain its international vocation. In this regard, although Europe and Latin America are its main markets, the company pays very special attention to others, such as Qatar and Taiwan, as well as the African market, a real challenge for the energy sector.
