Below are examples of some of our installations on New Generators ranging from single unit standby generators, to multiple set synchronised standby generators and multiple set prime powered generators for exporting to the grid. We offer a full range of Automatic Transfer Switches, Fuel Tanks and control Systems to support our customers in finding the right solution for your needs.
A FW Power installation comprising of 2 x 509 kVA Teksan generators synchronised together with a common 3,000L bunded fuel tank. The system provides back-up for a well known distribution warehouse in Milton Keynes and operates as a synchronised pair of generators that loadshare upon mains failure. Each generator has the capacity to run the site thus providing additional security to the sites power supply. The generators were linked into the customers own Automatic Transfer Switch with additional outputs added for information required by the clients SCADA system.
The addition of the 3,000L bunded fuel cube allowed either generator to run on full load for over 24 hours. What is not clear in the photo is that the ground sloped sharply away from the generators and as such multiple variable thickness concrete pads were added to level the site whilst allowing for ease of future maintenance.
The picture above shows an FW Power installation of 4 x 580 kVA diesel generators used to export power into the national grid operating 24/7 and 365 days of the year. The whole system comprised of 8 identical generators with a further bank of 4 operating on the same site. Each generator has a Deep Sea 8610 synchronising system fitted enabling each bank of 4 generators to produce over 2,300 kVA into the grid if required. The whole project was supplied, installed and commissioned within 3 months of the initial phone call – something that no other generator company could achieve.
The generators have Motorised Circuit Breakers that close directly onto the live bus and are also electrically interlocked into the G59 relay to instantly open the breakers in the event of either a fault or if they fall out of synch with the mains.
The two images above show an FW Power installation of a 300 kVA diesel generator used for standby power at one of the UK’s leading distribution centres. The generator features an additional 600 amp connection box fitted to allow connection of the clients 300mm per phase armoured cabling. A Deep Sea control system provides for automatic starting via the customers Automatic Transfer Switch.
Teksan Generators was founded in 1994 and now operates from a state-of-the-art facility from which Generators are produced from 9 kVA to 2784 kVA and exports to over 100 countries.

*Image above shows the Perkins 6.354 produced from 1961 to the late 1990’s and a modern 2806 Series Engine.
Back in 1932 Perkins was established in Peterborough England and recognised the potential of providing off highway power using diesel engines. It expanded its range of power output and manufacturing facilities by purchasing Rolls Royce Diesels in Shrewsbury, L Gardner and Sons and Dorman Diesels in Stafford. A large supplier to Caterpillar since the 1970’s, Perkins was itself purchased by Caterpillar in 1998. Perkins is now a truly global brand having manufacturing facilities in the UK, USA, Brazil and China as well as a joint-venture in Japan.

Cummins is a global power leader providing engines for agricultural, defence, construction, automotive, marine and power generation. Its engine range covers 10 kVA to 3,750 kVA and spans 1.7 to 95 Litres displacement.
*Image above shows the Cummins Model F from 1921 and a modern QSK78 Diesel Engine.
In 1919 Clessie Cummins established the Cummins Engine Company in Columbus USA with the aid of banker William G lrwin. Cummins quickly outgrew William Irwin’s garage and set up a machine works on the first floor of a former cereal mill to take advantage of the ground breaking technology which Rudolf Diesel developed in the late 1800’s.
In 1929 Cummins introduced the single disc fuel system giving the ability to generate injection pressure in each cylinder which distinguished the company from all other commercially available fuel systems. By 1932 Cummins had started to dominate the truck market with the introduction of the H672 which would be a force in the market for the next 25 years and the engine would be seen on the road for the next 70 years. By 1955 Cummins had 51% of the US diesel truck market.
In 1956 Cummins opened up its first plant in Scotland called Shotts, shortly followed in 1959 by the opening of its Brazil manufacturing plant. Expansion continued in 1962 forging an alliance with Komatsu which marked its entry into East Asia. Also in 1962 Cummins entered the Indian market with the establishment of the Kiloskar plant. After rapid development in 1964 Cummins establishes a natural gas engine and then in 1965 opens up its production plant in Darlington, UK. In 1973 Cummins purchased Holset turbochargers and in 1976 reached sales of $1 billion.
Through rapid expansion over the coming years many new facilities were added including the Jamestown engine plant New York, USA and the San Luis Potosi plant in Mexico. By 1981 Cummins had established a licensing agreement in China and by 1986 Cummins had acquired Newage Alternators. In 1998 Cummins began production of its ISX series of emissions certified engines and in the same year launched a 16 cylinder QSK 60 engine followed by the 12 cylinder QSK 45 – these engines would go on to lead the way for Cummins to become one of the most successful high-speed high-hp engine manufacturers.
In 2007 Cummins partnered with the Beijing based Beiqi Foton Motor Company in a 50-50 joint-venture to produce light duty high-performance diesel engines and by 2009 had created the F3.8 which was Cummins first engine designed, developed and manufactured outside the USA – the engine would become available in Brazil and Russia with sales of 250,000 engines per year. The partnership with China enabled production to start in 2014 of the ISG 12 engine and would allow Cummins to gain entry into the Chinese mainstream heavy duty truck market. The engine would result in the fastest heavy duty volume ramp up in the company’s history.
In 2015 Cummins started to produce the QSK 95 engine capable of producing 5000 hp at the Seymour Engine Plant. In 2018 Cummins advanced its electrical power division and it unveiled the AEOS– a fully certified electrified heavy duty truck capable of pulling a 22 ton trailer.
In 2018 Cummins revenue reached $23.8 billion and employed 62,600 employees across every continent.

Founded in Marseille (France), Baudouin has been manufacturing engines since 1918 and has a diesel generator power range spanning 15 – 2750 kVA.
The Baudouin family (Eugene Baudouin) were foundry owners in Marseille during the 19th century. Eugenes son Charles, had an interest in mechanical engineering and in 1904 he unveiled a small experimental petrol engine attached to a canoe which he powered from Toulon to Algeria – 750 km away !! This was the first official Baudouin engine.
*Images show early Baudouin Engines.
By 1922 the company was manufacturing standard engines from 3 to 60 hp and by the end of the 1920’s Baudouin was ranked in the top three manufacturers worldwide for marine engines. Baudouin has always been at the centre of innovation – it was the first company to manufacture engines using individual cylinder heads which meant maintenance could take place on one cylinder without dismantling the others, giving considerable cost savings to owners. They were also the first engine to feature a rotation speed of 750 rpm almost doubling the speeds of previous engines. To capitalise on its success and its dominant position within the marine market, Baudouin extended its product range to include gearboxes, propellers and diesel engines and within a 10 year period it sold 22,000 of these engines.
By the end of the 1960s Baudouin was producing engines up to 680 hp at 1800 rpm. Such was Baudouins’ success that in the 70’s and 80’s it partnered with John Deere and Renault producing engines known as the “D” and “R” series. In 2009 Baudouin was purchased by Weichai Power who over a 10 year period have invested over €100m, boosted productivity and significantly increased the workforce in France. It developed a new range of V6, V8 and V12 engines and today has a presence in over 100 countries.

Leroy Somer Alternators:
Leroy Somer is a global leader in the manufacture and supply of alternators with powers ranging from 10 kW to 25 MW. Founded in France in 1999 Leroy Somer has two manufacturing facilities in France, 28 production locations throughout the world including Hungry, Poland, Romania, China and India and employs almost 10,000 people. Bought out in 2017 by the Nidec Group of Japan, Leroy Somer is now a global powerhouse for the manufacture of alternators and motors.
*Pictured left to right: Leroy Somer, Cummins Generator technologies (Stamford & AVK) and a Meccalte Alternator.
Cummins Generator Technologies:
Cummins Generator Technologies manufacturers alternators under the brand names of Stamford and AVK with a range from 7.5 to 11,200 kVA. Newage Stamford was founded in 1935 as the Northern Electric Wireless and General Engineering Company and changed its name in 1988 to Newage International. In 1973 it produced its first generator with a Permanent Magnet Synchronous Generator (PMG). It was sold in 1986 to Cummins UK and became known as Cummins Generator Technologies and was branded along with AVK SEG in 2001. In 2017 the name was changed back to Stamford AVK – Stamford being the brand name that most people throughout the world recognised. Stamfords main manufacturing locations are in China, Romania and India with an alternator technology centre in the UK which will add manufacturing capabilities in the near future
Meccalte is the largest independent producer of alternators from 1 to 5000 kVA. Established in 1947 in Italy, today it employs 1200 people and produces 500,000 alternators a year. Meccalte manufacturers in Italy, India, China and the UK.
Voltage Regulation – Automatic Voltage Regulator:
All three companies use electronic regulation of the voltage which centres around an Automatic Voltage Regulator (AVR). The AVR monitors the alternator output voltage against preset levels and adjusts the output from the AVR to the excitation field windings – this closed loop constant monitoring system adjusts the voltage output to changing load conditions. There are two ways to provide power to the AVR. The first method is to use a Permanent Magnet Generator (PMG) which is mounted on the common shaft at the rear of the alternator; the second approach is to have a dedicated auxiliary winding placed within the main stator – in this method the dedicated power source is isolated from any electrical effects that may occur within the main stator. The role of both systems is to provide a steady state voltage. Cummins and Leroy Somer use the Permanent Magnet Generator system whilst Meccalte uses the self excited system from the excitor stator field. From a performance perspective both systems are more or less equivalent.

Deep Sea Electronics provides the control system for all FW Power Generators. Its range covers basic manual start controllers to autostart/automatic mains failure (AMF) controllers through to full multiset synchronisation systems. Deep Sea also has a range of controllers for automatic transfer switches (ATS) and a range of battery chargers. It has become a leader in the UK and Europe for non-proprietary control systems allowing operators and engineers to easily interrogate the control system and to change parameters unlike in a proprietary system where the manufacturers and the Genset manufacturers closely control who is able to adjust the control systems which often results in both timely and expensive service call outs from the manufacturers for basic control panel interrogation.
