Rising competitors for wind turbine service income is forcing authentic tools producers to up their sport in one other necessary service for the tools they make — distant diagnostics.
This month, for instance, Siemens Gamesa Renewable Vitality (SGRE) revealed that its Mannequin-Based mostly Diagnostics system has been upgraded to work with machines of any make.
The system, which has been in operation since 2011 and makes use of as many as 500 predictive fashions to evaluate the probability of element failures, is already analyzing information from round 17,000 onshore and offshore generators within the SGRE fleet throughout 44 international locations.
“We at the moment are creating fashions for GE, Senvion or Vestas generators, for instance,” an SGRE spokesperson mentioned in an electronic mail. “Our goal is to cowl extra programs with much more superior fashions.”
The Mannequin-Based mostly Diagnostics system is an inner device that SGRE makes use of to enhance the worth of its full-service contracts. It really works by on the lookout for information alerts which were related to element failures up to now, anticipating faults and flagging when an element might should be fastened or swapped out.
SGRE estimates the device has flagged up 50,000 potential failures over the past 9 years and helped the corporate perform preventive upkeep to keep away from greater than 1,000,000 hours of turbine downtime.
This sort of diagnostic experience might help resolve a serious headache for the wind trade. Unexpected breakdowns price the sector round $eight.5 billion a yr, based on Wooden Mackenzie. They can even shorten the lifespan of generators by stressing elements indirectly associated to the failure.
“There is a mutual profit right here,” Henrik Pedersen, SGRE’s answer architect for diagnostic intelligence, mentioned in an interview. “We spend a bit bit much less on doing the service exercise for the shopper, and the shopper will get further power manufacturing.”
The battle for service contracts
SGRE believes the Mannequin-Based mostly Diagnostics system might serve to boost loyalty to the corporate’s full-service contracts, Pedersen mentioned. And there’s no doubt that the necessity to develop service income is a high-priority concern for many main wind authentic tools producers.
OEMs are providing prolonged service contracts as a means of shoring up income amid ongoing market strain to create cheaper generators with decrease levelized power prices.
Though competitors on this space is fierce, current analysis exhibits full-wrap operations and upkeep prices per turbine have risen by greater than 12 p.c over the past 10 years.
Nevertheless, for now, it stays unclear whether or not diagnostics programs equivalent to Mannequin-Based mostly Diagnostics can actually improve buyer loyalty — or whether or not they’re merely a means for OEMs to chop in-house prices in an more and more cutthroat market.
Giant asset house owners, equivalent to Enel Inexperienced Energy of Italy, generally want to handle operations and upkeep in home.
“OEMs’ capability for distant monitoring doesn’t affect Enel’s turbine buy selections,” mentioned Luigi La Pegna, head of world operations and upkeep at Enel Inexperienced Energy.
“Our technique is to carry out monitoring internally, leveraging our group’s technical experience and digital platforms. Enel’s ‘digital eyes’ are getting even nearer to property and native workers due to new rising applied sciences like good glasses [and] edge computing,” he mentioned in an electronic mail.
For a lot of, the main target is solely on efficiency fairly than the tech that delivers it.
“If I put myself within the sneakers of the client of generators, I’m not going to care in any respect about what know-how they’re utilizing with the intention to make it possible for I get the provision that I would like,” mentioned Jonas Corné, CEO and founding father of the asset administration software program developer Greenbyte, in an interview.
“What I would favor is that I simply get an hermetic contract that tells me I’ll get 98 p.c energy-based availability — and even higher, that I get 98 p.c revenue-based availability. In the event that they’re utilizing machine studying or no matter, that will not actually matter to me. I’d be on the lookout for safety.”
Independents reluctant to take the distant diagnostic plunge
The entry to huge mental property, turbine information and computing energy that OEMs have ought to, in principle, give them a transparent edge relating to service supply, mentioned Corné.
This doesn’t look like the case in apply, although, which is why unbiased service suppliers nonetheless occupy a big area of interest out there and there’s a rising development for asset house owners to convey servicing in-house.
“A telling level is that in the USA, a number of massive asset house owners depend on the power of operational practices fairly than digital know-how,” mentioned Daniel Liu, principal analyst for renewable power operations and asset administration at Wooden Mackenzie Energy & Renewables.
“What they’re actively signaling is that they don’t assume there is a use case with distant diagnostic programs.”
Corné, too, mentioned distant diagnostics are not a daily subject of dialog with wind farm house owners. That’s to not say they may not admire instruments to enhance the profitability of their property, in fact.
However the perceived cost-benefit of such instruments is low, and until they’re bundled in present full-service contracts, turbine producers might want to overcome asset proprietor considerations on price versus advantage of deploying digital evaluation programs for operations and upkeep.
“Basically, many asset house owners should not but keen to spend capital and refurbish present fleets with the infrastructure essential to comprehend the total advantages of digital evaluation,” mentioned Liu.
