The contract recently awarded by E.ON Kernkraft GmbH has a volume of €11.25m ($16m). In the next few years, the replacement of emergency power systems in several German nuclear power plants is due; this also includes the Unterweser nuclear plant, which requires additional new emergency gensets.

The strategic significance of this order for possible follow-up orders is enormous, the firm said. Both emergency gensets are based on the MTU 16V 956 TB 33 engine and have a joint electric power output of 9400 kW. This equals the energy consumption of a small German town with a population of about 10 000.

Following the start signal, it takes the gensets less than ten seconds to reach their operating speed so that electrical power can be generated; after not more than 15 seconds, they accept full load. At Unterweser, they will supply safety-relevant consumers with energy in case of power failure.

The premium emergency gensets of MTU Onsite Energy fulfill, among other items, the stringent requirements of the German Nuclear Safety Standards Commission (KTA) for the operation of emergency power systems in nuclear power plants. This proof of operational reliability and safety had to be demonstrated in extensive trials under the supervision of Germanischer Lloyd.

What makes the gensets stand out in the first place is their exceptional reliability. Tognum is one of four providers worldwide whose emergency gensets are approved for operation in nuclear power plants.

For more than thirty years, several MTU emergency gensets have been in operation at the NPP Unterweser. As part of an extensive repowering programme, E.ON will first integrate new emergency power systems. To this effect, Tognum was awarded the contract for the two MTU Onsite Energy 16V 956 TB 33 gensets.

The specialist for propulsion and power solutions scored primarily with the excellent quality of its gensets as requested by the customer and the great expertise of its engineering personnel. The contract for two additional, smaller gensets is yet to be awarded.

“With its emergency gensets, Tognum contributes essentially to the safety of nuclear power plants, not only in Germany but also in China, for example, as our recent successes show”, explained Christof von Branconi, member of the executive board of Tognum AG and responsible for the business unit “Onsite Energy & Components”.

Only a few months ago, the Tognum subsidiary MTU Friedrichshafen, as part of a consortium, had sold emergency power systems with a total value of about €150m to Chinese nuclear power plants. “In our strategy to expand our business, emergency gensets for nuclear power plants represent an important mainstay”, added von Branconi.

Wärtsilä strengthens position in the eastern Mediterranean with power plant orders from Greece and Cyprus

Wärtsilä is boosting the power capacity of the Eastern Mediterranean islands with the award of two orders in Greece and Cyprus.

One order has been received to supply power generation equipment to the island of Lesvos belonging to Greece, and the other to Cyprus. The combined value of these orders is approximately €40m ($56m). These orders were taken into the order book during the first half of this year.

The contracts represent a total output of 72 MWe. The two new orders bring Wärtsilä’s power generating capacity in the region, either installed or on order, to more than 600 MW. Local electricity demand surges dramatically during the tourist season when the resident population of some 120 000 people is outnumbered many times over by tourists.

Wärtsilä’s decentralized power plants offer a flexible and highly efficient means of meeting these increases in demand, whilst at the same time creating low environmental impact.

The strict environmental protection norms of the EU require that the power plants are equipped with the best available harmful emission reduction technologies, and that they use very low sulphur content fuel oils. The Wärtsilä engines are equipped with the latest low emission technical solutions. Furthermore, since the Cyprus plant is located near the town of Larnaca, it is also equipped with a separate nitrogen oxides reduction system to remove most of the flue gas nitrogen oxides.

“There is a strong need to meet this seasonal demand for energy since it has such an impact on the local economy. The key requirements are for heavy duty units that can run on heavy fuel oil at full power during the five summer months while, at the same time, having the lowest emissions.” says Harry Lindroos, Regional Director, Eastern Europe, Wärtsilä Power Plants.

The state-owned Public Power Corporation has awarded turnkey contract for Wärtsilä to supply additional generating capacity to its power plants on the Greek island of Lesvos.

The contract represents an extension to an existing power plant, with the extra 22 MW capacity needed to meet the huge increase in demand that occurs during the tourist season.

The Electricity Authority of Cyprus (EAC), a public utility, has ordered a power plant with three Wärtsilä 18V46 engines, which will deliver over 50 MWe of energy.

The new plant is located in Dhekelia, near the town of Larnaca in Cyprus. The new plant is a turnkey delivery by the Danish contractor BWSC, and is scheduled for full operation in summer 2010.
