Power & Energy Solutions

The premier renewable energy publication

In February 2015, the Indian government announced its plans to almost quadruple its renewable power capacity to 175 GW by 2022 as part of the plan to supply electricity to every household in the country. This includes 60 GW from wind energy. Further, India made a commitment at COP21 to raise the share of non-fossil-fuel power capacity in the country’s power mix to 40% by 2030. Consequently, these plans and targets make the Indian market a unique fast moving and growing market where competitive companies can have great business opportunities. But, they also come with a complex and unstable legal framework where manufacturers find many obstacles on the way. Market developments In 2016, India set a national record with 3,612 MW of new installations, bringing the country’s total to 28,700 MW and consolidating its 4th position in the cumulative global rankings, according to the Ministry of New and Renewable Energy (MNRE) of India. India was among the top 10 countries in terms of renewable energy investment, according to UNEP & Bloomberg New Energy Finance. Also, India’s renewable energy sector held its position at the third spot for the second year in a row in the Renewable Energy Country Attractiveness Index (RECAI) released by

A new innovative approach to windfarms could, at last, make them more popular and community friendly. Bringing the benefits and the profits home to local communities. Daniel Dubbelhuis, Account Manager Netherlands at Lagerwey tells us how. Large multi megawatt parks in concentrated areas developed by and for the local community, anonymous big developers - ensure further anonymization of wind turbines. Local residents feel that they get saddled with a problem that they have not asked for, resulting in a growing resistance to on land wind turbines. The last 10-20 years have shown how not to develop wind projects. The parties ultimately end up in court, each trying to get their own way. In the meantime sustainable energy becomes a conflict between developers and local residents. Why do we develop both large and small wind farms in this way? Why with each project achieved do we create more resistance to wind power? Shouldn’t the sustainability aspect also be reflected in the relationship between all the actors in a project?

The latest UAV (unmanned aerial vehicle) technology allows swift, thorough inspections to assess turbines. Drones can be used either as part of routine reporting or for detailed inspections in preparations for rope access teams. This has many significant health and safety benefits for the technical teams in terms of assuring all anchor points are secure and preparing in advance for any repair work that will need to be done at height. Here, UAVONIC Ltd, shares the fundamentals of a typical aerial inspection and how wind O&M teams can benefit. UAVONIC works closely with inspection engineers to give the UAV Operators a good understanding of the wind turbine’s structure. So when on site with a client, pilots can understand the issues most commonly discovered upon inspection and what is required for the inspecting Engineer. When doing an inspection on a wind farm usually an inspection Engineer from the site would be present with the UAVONIC UAV team. There may be specific issues he is already aware of that he will want the pilot and camera operator to focus on, but all project plans will look similar consisting of the following scope of work:

Words: Thomas Arnold and Thomas Zirngibl, TÜV SÜD Industrie Service GmbH The recently revised TR6 Technical Guideline of the German Public Association of the Renewable Energy Sector (Fördergesellschaft Windenergie (FGW)) is designed to ensure the provision of reliable yield forecasts. Wind reports based on the Guideline play a critical role for producing reliable estimates of the profitability of a wind-farm project. In the past, turbines have often been shown to deliver lower energy levels than their reported estimates. The ninth revision of TR 6  now specifies methods that will help to produce realistic forecasts of actual on-site wind conditions. Wind speed and direction at the proposed site of a wind farm are critical factors in determining whether wind farm operation will be cost-effective over the long term. Previous practice has shown that measurements and evaluations of wind and weather data may be over-optimistic, favouring the stakeholders’ own interests. At least two wind reports issued by third-party organisations are therefore necessary to convince banks and investors of the profitability of a wind-farm project in order to secure financing. Independent accredited assessors are therefore commissioned to verify the yield forecast of a planned project. As these forecasts are always based on varying project-specific facts, figures

Words: Lindsay Roberts, Senior Policy Manager, Scottish Renewables Renewable energy is now our largest source of power and with over 5.5GW installed onshore, wind provides the lion’s share of that capacity. Can the Scottish and UK Governments work with industry and regulators to remove a series of barriers as suggested in a report by Everoze and explained here by Lindsay Roberts, Senior Policy Manager at Scottish Renewables? The sector has delivered hugely impressive cost reductions, leading some commentators to claim that it is already the cheapest form of new electricity generation plant on the market. It’s perhaps not surprising then that the appetite for further development remains undiminished, with another 7GW of capacity waiting in the wings. That pipeline, however, faces an uncertain future without a viable route to market. What is certain is that a successful future depends on our ability to reduce costs even further. Earlier this year (2016) Scottish Renewables commissioned energy consultancy Everoze to examine just how low the cost of onshore wind in Scotland could go and the steps needed to get us there.

The Race Bank Wind farm is being constructed by DONG Energy approximately 27 kilometres off Blakeney Point on the North Norfolk coast and 28 kilometres off the Lincolnshire Coast and Chapel St Leonards. It covers an area of 7511ha. Export cables bring the power from the wind farm to the substation onshore. These export cables run through the Wash and come ashore east to the mouth of the river Nene and approximately 6 km northeast of Sutton Bridge. The cables ashore run further in a southerly direction to the connections point at the existing Walpole Substation. The two export cables are both approximately 70km long and the two Offshore Substations (OSS) are linked with an interconnector of 4km. In March 2015 Jan De Nul was awarded a contract for the installation and burial of both export cables and the interlink cable.    Here we focus on the installation of the intertidal parts of the export cables and its special challenges. Environment The intertidal areas of The Wash compromise up to 10% of England’s saltmarshes and form one of England’s most important natural habitats. Mitigating any potential for the installation works to impact on these habitats is a key priority and measures to ensure that works

Words: Steve Sawyer, secretary general at GWEC The dramatic drop in price of solar and wind generated electricity, for solar in particular, has grabbed a lot of attention lately. Prices in the range of $US 0.03-0.04/kWh have come through in tenders from Peru to Mexico and Morocco to South Africa. It is almost to the point where in the big picture, price doesn’t matter so much anymore. As penetration levels begin to increase, the emphasis will be much more on how to integrate them into the power system, or rather to transform the power system to work with wind and solar’s particular characteristics. But when people are talking about wind, they are increasingly adding ‘onshore’, to distinguish it from its large, slow and expensive cousin, offshore wind. But maybe not for much longer. There has been a lot of positive news from the increasingly dynamic offshore sector of late. Until recently the best prices we had heard of for offshore was €103/MWh for the Horns Rev extension in early 2015, which was considered a very positive sign of things to come. However, just about everyone was surprised by the record low prices in the Dutch auction for 700 MW at the Borssele offshore
