FOUNDATIONOnshore wind developers on the Scottish mainland have moved deutsche-windtechnik.cominto emerging markets too.New technology such as energy storage and demand-sideresponse present new opportunities for onshore wind projects toincrease the services they can offer the grid.Delegates at Scottish Renewables Annual Conference, held inEdinburgh in March, heard a new type of power purchaseagreement could provide new routes to market for onshore windprojects at all scales.An increasing focus on energy costs combined with a desire frombusinesses to ‘green’ their supply chain is providing a strong pushto engage more directly with generators, while the move from fixedsubsidies to a more competitive market for generators has meantany certainty in the project finance stage is welcome.Corporate PPAs are increasingly being seen as a way to bridge thegap between these parties, securing benefits for both.Early corporate PPA movers in the UK include Marks & Spencer,whose multi-award winning “Price Guarantee Agreement” was arelatively simple form of contract for difference, and latterlymajor corporates including BT, Nestle, McDonalds, HSBC,Lloyds, and Nationwide.While this type of contract could become more popular for anindustry increasingly working in a post-subsidy world, the numberof corporates able to engage in the market may also limit the size ofthe opportunity.The requirement for more wind power is clear. The ScottishGovernment’s draft Energy Strategy, which is out for consultationuntil the end of May, contains an ambitious target first suggestedby Scottish Renewables: generating the equivalent of 50% of thecountry’s total electricity, heat and transport demand fromrenewables by 2030.Doing that, the Scottish Government’s figures show, would requiresignificant new deployment of renewable electricity generation –capacity which could be met not only by new onshore wind sites butalso by the repowering of existing ones with more powerful turbines.So while offshore wind sites in Scotland’s Forth and Tay estuariesstill awaiting the outcome of an appeal against a judicial reviewwhich saw their consents challenged on environmental groundsand the UK Government’s moratorium on onshore wind remains,there are grounds for hope.And while corporate PPAs, energy storage, the ScottishGovernment’s draft Energy Strategy and the potential harvesting ofthe islands’ wind resource don’t provide answers on their own,together they show that the appetite for wind energy in Scotlandremains as strong as ever. Scottish Renewables’ Onshore Wind Conference and Storage and Systems Conference are being held in Glasgow on June 20 and 21 respectively. www.scottishrenewables.com/events for more details.

PES ESSENTIALCan bidders in the recent andupcoming German tenderprocess, for offshore windpower, enforce the award?Words: Linda Blunk in cooperation with Blanke Meier Evers Project developers of offshore wind power have concerns, even anxieties, which mirror their apprehension about a basic injustice which just took place during the tendering process pursuant to the new German Offshore Wind Energy Act (WindSeeG).Linda Blunk This apprehension has already led to In the realm of offshore wind energy there numerous legal inquiries which focus on the were also numerous bidders with scant following question: Is the tendering chance of success who were in competition procedure pursuant to the WindSeeG with handful of bidders with good unconstitutional, more specifically, can a prospects.

According to Transition Period this model, bidders compete for the building of a specific wind park, prescribed There are numerous examples in German by the Federal Grid Agency jurisdiction, where tender results have been (Bundesnetzagentur) at a site pre-examined set aside by a court. For example, by the Federal Maritime and Hydrographic Landgericht Köln (Regional Court, Cologne) Agency (Bundesamt für Seeschifffahrt und recently ruled in favour of a utility company, Hydrographie). However, this central model providing energy, water and waste disposal, will apply only after a transition period, due that had alleged that the tender process to the long lead times needed for planning had been ‘opaque and discriminatory’ and approval procedure. because at an early stage a certain bidder (“ENWOR”) had been favoured, thus During the transition period, for wind farms robbing other bidders of their chance of that will be commissioned between 2021 success and stage managing the process. and 2024, there will be a different model. www.peswind.com 13

This model corrects any imbalances arising from locations with strong or weak wind speeds, by introducing a correcting factor that lowers or raises the bidding price. Lowering it for a project location with sluggish wind and raising it for a location enjoying strong winds. A similar concept hasn’t been put in place for the offshore auction system, although offshore projects are subject to a much larger number of price factors than onshore projects. To sum up, there must be grave misgivings whether the transitional tendering procedure can be deemed fair and non-discriminatory. There are even serious indications that it violates constitutional law because even before the publishing of the tendering results the probable winner of the bidding process could have been predicted.

Niels Noordeloos: “There are three stages in wind energy. The first one is investigation. In the investigation phase, we offer our clients geotechnical and geophysical surveys, as well as logistic support. In the second phase, construction, we deliver guard vessels, ERRV (emergency response and rescue vessels), logistic support and above and below water services. Then comes the operation and maintenance (O&M) phase. This third stage is highly underestimated but takes about twenty years. In the O&M phase we offer above and below water inspections from our vessels. Above water inspections are executed by using drone technique and rope access. Below water inspections are executed by using an inspection class ROV and, if so required, divers.” OPS is always searching to combine offshore and onshore tasks to realise the most efficient project possible. Niels Noordeloos: “For example, we have sailed out with our vessels to an offshore wind farm, where we inspected above water by using a drone and at the same time used the ROV for below water inspections. Both drone and ROV came back on deck and we sailed to the next location.” A full inspection in one run. OPS is one team working as a multiple service provider for all three stages. “That means one contract, one legal party, less office hours and just one vocal point of contact for a complete project.” Toolbox at sea Niels Noordeloos is ambitious and very outgoing. He is a firm believer in the power of collaboration. “Working together on beautiful projects, that’s all I really want to do. I’m really looking forward to working with new clients and offering them what we like to call our ‘toolbox at sea’. No matter what stage you are in or what is needed, everything is in there. It’s what makes us the most efficient, cost reducing and safe choice for every company looking for a partner in wind energy. ‘Their business, our service’, that’s my motto.

For nearshore wind farms this was less of an issue. However when offshore wind farms began to be situated sometimes two or three hours sail at high speeds from port this added significant delays to operations and requisite weather windows. The cable lay vessel also posed a problem, as the inter array cable installation solutions which were swift enough to undertake the cable lay work efficiently tended not to have the tonnage capacity to take sufficient cables offshore requiring the need for repeated trips to and from port. Alternatively, those ships which could take sufficient cables and cable protection systems tended to be slow and expensive. A particular set of requirements took shape, for subsea cable installation on offshore wind farms, in far from shore, harsh environments. It required a task specific cable lay vessel which could work unaided in conditions up to 3m significant wave height, while staying offshore for long periods without the need to return to port to collect cables and/or personnel.
