Globally, Europe has the highest capacity of power generated from offshore wind energy. Amongst the European countries, Denmark, the UK and Germany have been pioneers and are currently leading as the largest power producers from offshore wind energy. Danish assistance has been in high demand to help countries shorten their implementation time for offshore wind turbine projects. In 2019, India entered into a bilateral agreement with Denmark to develop an offshore wind market and related technical capabilities. According to a document published by the Danish government, their authorities have specialised technical knowledge that can help Indian authorities establish framework conditions for the rollout of offshore wind power.
Denmark’s Offshore Wind Energy Sector
The Danish Government has set a target of reducing greenhouse gas emissions by 70%, as compared to 1990 levels, by 2030 and having 100% of Danish energy supplied through renewable sources by 2050, apart from achieving net-zero emissions by the same time. The scarcity of proper onshore sites and the abundance of shallow waters with wind resources drove its move to offshore wind, in the early 1990s,. In Denmark, there is a strong symbiosis between energy and industrial policy because of many leading offshore wind energy companies having Danish roots such as DONG, Vestas, Bladt, Siemens Wind, etc. India must achieve such a symbiosis in its offshore wind policies so that the industry can be successful in the long term.
Denmark’s ambitious targets coupled with their evolving policies in terms of bureaucratic procedures, environmental safety, and finance, among others, have driven the growth of the offshore wind energy sector since the 90s. This analysis looks at each of these segments.
Consent Procedures: The Danish Energy Agency (DEA) has been a single point of access to all offshore wind energy companies when it comes to issues related to permits. Meaning, the DEA grants all permits which include permits from other appropriate government authorities such as the Danish Nature Agency, Ministry of Defence, and the Danish Maritime Authority. This is the one-stop-shop and has been adopted not only in Denmark but in many other European countries. Such a method ensures rapid and un-bureaucratic application processing and ease of doing business. This also avoids a lot of confusion.
Grid Connectivity: The financing of the grid connection for offshore wind farms depends on how it is established:
- Enterprises can follow the Government’s action plan for offshore wind development wherein the DEA will invite bids to tender for pre-specified sites or
- Enterprises can follow the ‘open-door principle’ wherein independent applications can be made for any site and upon complete assessment by the DEA, it will invite bids to tender for the site, given that the results of the assessment are positive.
In the first case, the grid operator will finance the connection, including step-up transformers. Such socialisation of grid costs is an attractive feature for project developers in Denmark.
However, in the second case, the responsibility falls on the developer. We may also expect costs of any necessary grid reinforcement to be borne by the developer. The three private offshore wind farms established in Denmark, following the ‘open-door principle’ – Samsø, Rønland, and Middelgrunden – have had no notable problems. These projects are, however, within 3km of the coast, which would imply that the grid connection costs were not exorbitant.
Environmental Assessment: In Denmark, an extensive environmental assessment takes place before the construction of an offshore wind farm. The DEA provides companies or enterprises a license to conduct preliminary studies, including environmental (Environmental Impact Assessment) and technical (ground investigation) studies, either directly after a tender (first process) or following the receipt of the first satisfactory planning documentation (second process).
For instance, in the case of the Anholt farm, one of the largest offshore wind farms with a capacity of 400 MW, the project team performed an extensive environmental assessment that included the impact on marine animals in the area and their habitats, noise calculations, air emissions, and the potential risk to ship traffic. Using data from other wind farm projects like Denmark’s Nysted Wind Farm, and undergoing their analysis, the Anholt project team projected only minor, insignificant affects.
Financial Incentives: In Denmark, they support offshore wind farms through a feed-in tariff system, which is set through a competitive auction process. Power off-take in Denmark is largely managed through the DEA. There is no renewable purchase obligation in place in Denmark, but electrical power from renewable energy has priority access to the grid. In some cases, the owner may choose to sell the electrical power to utilities or other power suppliers through a Power Purchase Agreement (PPA). If the power price drops to zero or negative, there is an oversupply of electricity – then renewable projects do not receive any support. Hence this motivates generators to curtail output and help supply-side grid management.
De-risking the development process: The Danish Government undertakes geotechnical studies, wind resource assessment, and environmental surveys before a site being leased. The lease areas are then auctioned off to the lowest bidder. This hugely benefits developers as the site is effectively de-risked, leading to a lower tender price. If this were not the case, the developers would have to include risk provisions and contingency, owing to uncertainty regarding the ground conditions. Further, de-risking a site would increase willingness to plan and bid for the sites leased.
Simply put, the Danish offshore wind energy policies developed by the DEA and the Government have evolved over the years to tackle situations as they occur. This has led to sustained growth in the sector and has succeeded in powering close to 50% of the country’s electricity demand. Besides successfully developing its sector, it has been an outstanding example to many countries in Europe such as the UK and Germany. The UK has adopted the one-stop-shop model to ease procedural difficulties. Germany has adopted the open-door procedure of establishing offshore wind farms.
India’s Offshore Wind Energy Sector
The offshore wind energy sector in India is in its nascent stage. Its 2015 National Offshore Wind Energy Policy shows that the Ministry of New and Renewable Energy (MNRE) will act as the nodal Ministry for the development of Offshore Wind Energy in India that will monitor offshore wind energy development in the country. It will also work closely with other government entities for the use of maritime space within the Exclusive Economic Zone (EEZ).
The Ministry has set a short-term target of 5.0 GW of offshore wind installations by 2022 and a long-term target of 30 GW by 2030 which, according to government documents, is expected to give the confidence to project developers in the Indian market. Over 95% of commercially exploitable wind resources are concentrated in seven states – Andhra Pradesh, Gujarat, Karnataka, Madhya Pradesh, Maharashtra, Rajasthan, and Tamil Nadu. But the land resources required for onshore wind projects are gradually becoming a major constraint. This could very well cause an increase in the market-determined tariffs of onshore wind energy in the future. Offshore wind power, however, offers a viable alternative in such a scenario. The Indian government, like Denmark, has to make policies to the best of their effort that will bring confidence to developers and de-risk the development of the sector to further encourage developers.
Although India has a huge potential in the renewable energy sector, the developers’ issues remain unresolved. For instance, Gujarat and Tamil Nadu have most of the high potential sites off their coasts to develop offshore wind energy. But a major concern for offshore wind developers would be the problem of grid integration. The two states already have a high degree of solar and wind renewables integrated into their power grid. By adding on power generated through offshore wind energy, they will face a significant hurdle with the evacuation and integration of this additional power. Without proper renewable energy storage systems, there is also the added burden to maintain an equilibrium between the supply and demand of power generated through the variable sources as otherwise, there will be a great deal of wastage and an unnecessary surge in the prices.
Adding on to the problems faced by developers, benefits such as accelerated depreciation were recently withdrawn and as a result, investments have slowed down. Thus, project developers not only want accelerated depreciation to be reintroduced, but they also want assurance from the government that such fiscal benefits will continue for the long-term. If these fiscal benefits are reintroduced, developers will feel more optimistic about their prospects in the sector. Further, it would also encourage small developers to invest more in the sector.
Another area that is causing considerable angst for the wind project developers in India is the delay in realising the payments due to them from the state electricity boards. These delays affect the cash flows, thereby threatening the viability of many of these projects. Such experiences will make offshore project developers cautious in venturing into making large investments into the sector.
In terms of policies that Indian policymakers can adopt from Denmark are the one-stop-shop and an open-door procedure of establishing offshore wind farms. Having the MNRE as a single point of access would make the bidding and tendering process more efficient. This is because a developer has to coordinate with various departments such as the MNRE, the ministry of defence, the ministry of external affairs, nature and wildlife, etc before they can start producing in an offshore wind farm. It would also benefit to have an open-door procedure, but only in the long term. Initially, though, the government should identify possible sites and work on de-risking the development process to encourage more participation in the bidding process.
Conclusion
In line with its Paris Agreement commitments, India is working to ensure that by 2030, 40% of its power generation capacity will come from non-fossil fuel sources. Currently, renewable energy makes up 36% of India’s power capacity through mainly small and large hydro, onshore wind, and solar energy. Producing power through offshore wind energy will be a welcome addition to the existing sources.
During the RE-Invest 2020 conference, the MNRE Joint Secretary announced that the Indian government is looking into setting up structures for power purchase agreements and offshore wind auctions. Thus, to successfully implement its plans, it will require further offshore wind resource data and analysis to identify viable project sites and, revive industry demand for this market.
