In connection with the replacement of our 36-year-old gas engines, 4 pieces, we have made a market survey, where we have obtained information/data, as well as prices from 6 gas engine suppliers in Denmark for comparison.In addition, some mandatory requirements have been set for, among other things, the size of the generator set, services including electricity and heat output, as well as for regulatory requirements for emitted emissions and noise The following gas engine suppliers have been questioned during the market survey. JenBacher INNIO, Samsøvej 31, 8382 Hinnerup,Bergen Engines Denmark – Amalienborgvej 39, 9400 Nørresundby.MAN Energy Solutions SE, Stadtbachstrasse 1, 86153 Augsburg,Wärtsilä Denmark A/S, Kystvejen 100, 9400 Nørresundby DK,Zeppelin Danmark A/S, Øresundsvej 9, 6715 Esbjerg N,Deutz Nordic, Norddigesvej 6, 8240 Risskov – Denmark. The following requirements have been set for the new gas engine:Max number: 1 generator set with 10.5 KV output for ‘Griddet’Max contract price when purchasing 1 new gas engine/generator set: 7.5 Mill.kr. max 2.999 KWHeating power: a minimum of 3.5 MW and no more than 5 MW.Noise must comply with the applicable rules for the location – here reference is made to Brønderslev Municipality – Environment and Technology. Justification for the above 4 points.There is only room for 1 pc. gas engine in the machine room, therefore limitation to only 1 pc. new gas engine. The choice of delivery of 10.5 KV is that we can thereby save service and maintenance on the current 0.4/10 KV transformer, as there is no longer a need for it.To keep a reasonable price cap, it has been decided that the max contract price when purchasing a new gas engine/generator set must be limited to 7.5 Mill.kr. The size of the engine as we have set a requirement of max 2.999 KW will be characterized as a B-Installation, whereas if the engine is above 3 MW - it will be characterized as a C-plant, which will give an increasing cost of approximately 1 mill.kr. A less heat output than 3.5 MW will have a negative impact on our deliveries to our customers, therefore we have chosen a minimum of 3.5 MW heat output. A heat output of more than 5 MW will have a negative impact on our operations due to Accumulation tank capacity. For emission requirements for new gas engines, see Order No 1535. NOx: emission, dry flue gas 15% O2: ≤ 95 mg/nm3.CO: emission, dry flue gas 15% O2: ≤ 190 mg/nm3Conclusion of the market investigation.JenBacherJenBacher is the only engine manufacturer that can match the requirements. Be it on price, emission requirements, size, as well as electricity and heat output. This is a JenBacher J620 of 2,999 KW of electricity, and 3.5 MW of heat, as well as 10.5 KV.Moreover, it has been found that JenBacher is the only engine manufacturer that can supply a clean gas engine, all other engine manufacturers use modified diesel engines that are converted to gas operation.Bergen Gas Engine The smallest gas engine at Bergen Engines Denmark, is 9.4 MW, see the following website: https://www.bergenengines.com/engines/bergen-b3540v/Since their smallest 9.4 MW gas engine is too large, we can ignore this supplier. MAN Energy Solution SEThis engine manufacturer cannot supply a gas engine of 3 MW, the least they can supply is of 7 MW.Wärtsilä Denmark A/SDenne engine manufacturer cannot supply a gas engine of 3 MW, the least they can supply is of 6 MW.Their proposal is on a Marine model where the manufacturer will use it as a test rabbit for optimization equipment/parts, I see as a disruptive element and therefore not usable for our purposes. Zeppelin Denmark A/SDenne engine manufacturer can supply gas engine of 2.5 MW, which is too little from the perspective of the requirements we have set. Zeppelin tried to sell us 2 pcs. 2.5 MW, this requires extra costs for e.g. new foundation, 2 pcs. new flue gas exchangers, all in all this solution would exceed Max contract sum for the purchase of new gas engine of 7.5 Mill. Our requirements about max number of 1 new gas engine must be complied with, as we do not have the space for 2 gas engines of this size with associated flue gas exchangers. In addition, excessive noise problems may occur during operation. Deutz Nordic - MWMDenne engine manufacturer cannot comply with the emission requirements set, therefore we disregard this manufacturer.Requirements for NOx: emission, dry flue gas 15% O2: ≤ 95 mg/nm3The gas engine from Deutz Nordic can only produceNOx: emission, dry flue gas 15% O2: ≤ 500 mg/nm3
