ConsolidationThe slump of innovation investments seen in the wind industry back in 2013 is coming to an end. A healthier global market and replenished coffers have inspired a surge in new technology and product development. The global market downturn saw a 34% drop in patent filings in 2013 versus 2012. That same time frame also saw an industry-wide drop from 5.2 to 2.3% in average research & development (R&D) expenditure as a percentage of revenue. The full breadth of patent filings for 2014 will become public in July of this year,(1) but they appear to be trending upwards, with an 18% improvement over 2013 so far. In the meantime, an evaluation of the R&D spend signals a rebound back up to an industry average of 4.7% of revenue based on analysis of 2015 data.

Scale, global competitiveness and balance sheet strength have been core drivers behind recent deals in onshore wind. However, another by-product of these mergers and acquisitions is the combination of R&D resources.

This trend is important because of the ever-increasing cost associated with technology development, meaning that consolidation will result in a continued drop in levelised cost of energy (LCOE). In a maturing market, such as onshore wind in the past three years, the R&D investment and other non-recurring engineering costs for a new clean-sheet onshore wind turbine design are approximately € 120 million. An additional € 350–450 million is typically required for supply chain development and initial commercial demonstration.

The development programme for a new onshore blade could cost € 35–45 million in non-recurring engineering including the capital expense of the manufacturing tooling, testing and certification. A few companies attempted a switch from doubly-fed induction generators (DFIG) to permanent magnet generators (PMG) a few years ago, only to find the commercialisation costs of switching over their entire production and supply chain was too high a barrier without an appropriate order book to justify it. But pooling resources enables some of this stagnant product evolution to be more cost-effective with the newly expected global scale achievable thanks to the mergers.

Interestingly, this trend was started by the offshore wind sector. In the past five years, the industry has seen consolidation in the offshore sector partly due to the product development costs, but mostly due to the commercialisation costs presenting a steep barrier to market entry. Offshore product development will easily run into the € 150 million range, but the commercialisation costs including port infrastructure and manufacturing capacity, as well as supply chain development, easily send the total to around € 1 billion.

Companies without the ability to support such R&D and commercialisation investments either onshore or offshore will find difficulty competing in the new market environment with the combined companies who can.

This desire for technological differentiation and competitive advantage has proliferated to the rest of the supply chain as well with a series of recent technology and intellectual property (IP) asset acquisitions. The Vestas acquisition of the Modular Wind Energy (ModWind) technology and IP as well as the GE acquisition of Blade Dynamics speak to a need for re-invigoration of technology portfolios with assets of a certain maturity level.

The next few years are likely to see more of these type of technology focused deals, with an emphasis on three key areas. Companies at the forefront of materials and manufacturing technology, power plant control and data-enabled service providers are the highest priority targets.

Manufacturing technology is often overlooked when it comes to wind, but it represents one of the highest impact sectors of innovation in the industry. A shift towards metal–composite hybrid materials that take advantage of the strength of carbon, without the cost penalty, and incur only a modest weight increase versus carbon use, could shortly see their way into the blade, nacelle and perhaps eventually the tower. Additionally, additive manufacturing has yet to make a meaningful impact, but look for this to become more pervasive for subcomponent manufacturing of spar caps, shear webs, root elements and other structural components in the blade as well as other turbine components.

Overall, the design intent of the power plant control (PPC) system of the future is to increase annual energy production (AEP) and regulate wind turbine/wind park power output based upon demand and electricity price optimisation. The architecture of the PPC system of the future will deliver maximum output of price-optimised electricity while maintaining overall health of each turbine in the wind park. Certainly, the Internet of Things (IoT) will play an important role as an underlying platform on which the performance and price optimisation of the wind park will be evaluated and achieved.

For services, data analysis will be important, but data communication as well as visualisation of repair workflows will enable significant reductions in lost production time. The timely communication of service issues to the right level of technical skill will be key to identifying field issues and initiating suitable repairs. Tools which facilitate collaboration between on-site field technicians and remotely based engineers will enable faster diagnosis of turbine issues and faster implementation of solutions. A fully integrated platform which also feeds spares availability information will mitigate the downtime of the repair.

Joint ventures, partnerships, technology and IP licensing are poised to see a revival as the industry continues the path to cost parity and seeks the next level of technology.
