Wind Turbine Nacelle Market Growth Factors

Declining Cost of Wind Energy

Over the past ten years, there has been a dramatic decrease in the price of wind energy. Adopting higher and larger-sized wind turbines is the main factor contributing to the price decline. Previously, steel and aluminum-based components were the mainstays of the wind industry. If used to make big wind turbine blades, these materials are hefty and risk being broken. The wind industry has recently created more robust, lighter materials, including polymers and fiberglass composites.

Additionally, whereas in the past, the wind business mainly employed steel to construct enormous towers, today's wind towers are built of steel and concrete, allowing the producers to construct large towers. The gearbox for wind turbines now uses better bearing materials. In addition, there have been substantial advancements in the designs and production techniques during the past few years. These advancements have made it possible for producers of wind turbines to construct powerful wind turbines at a relatively reduced cost.

Market Restraint

Dearth of Technical Expertise

The electrical systems have the highest yearly failure rates of any fixed-base wind turbine component, exceeding 0.5 in some cases, with an average downtime of just under two days per failure, according to analyses of the failure rates of different components of the turbine. This is the outcome of numerous technical issues that also need trained experts. The need for experts and professionals is growing due to improved analysis methods for combined wind and wave loading present on FOWT installations, an adaptation of current manufacturing methods to enhance the performance of turbine blades, and optimization of power cabling connections for deep water offshore operations. A lack of technical expertise seriously hampers the offshore wind industry's progress.

Market Opportunity

Mounting Technological Advancement

Technological developments in the design of wind turbine components, like glass composites, to lower the cost of maintenance and installation will further extend lucrative opportunities to market players in the forecast period of 2022 to 2029. Modern glass composites construct smaller, cheaper, and more accessible transport and assemble components. These components are elementary to install and repair. Costs associated with installation and maintenance are thereby reduced, which will help the market grow.

Location of Deployment Insight

The onshore segment is the highest contributor to the market and is estimated to grow at a CAGR of 5.54% during the forecast period. When compared to offshore turbines, onshore wind turbine technology is more developed. Onshore wind turbines are generally less expensive and are built to operate at lower tolerance levels since they must withstand fewer environmental pressures than offshore turbines. Onshore wind turbine nacelles, however, are faced with difficulties, including abrasion damage from airborne dust and sand particles, and must employ unique designs to lessen the influence of environmental pressures. According to IRENA, a typical 2 MW onshore turbine has a nacelle assembly that weighs close to 2 tons. Most contemporary onshore nacelles use composites, despite previous ones using steel and stainless steel. They are frequently produced using glass fiber composites injected with resin to meet the demands of size, intricate geometrical design, and weight. Nacelles offer a secure working surface for maintenance employees as well as protection for the inner workings of the wind against external dangers such as precipitation, dust, UV radiation, and lightning strikes. 

Additionally, many significant OEMs have built nacelle manufacturing facilities in developing nations like India. In Chennai, Tamil Nadu, Siemens Gamesa has a nacelle plant, and Vestas has also announced plans to build a new nacelle and hub assembly facility there. In Daman, Gujarat, Suzlon has a nacelle cover manufacturing facility. These manufacturing facilities primarily produce onshore turbine nacelles because the Indian market is their primary customer, and the onshore sector dominates the Indian wind energy market.

Offshore wind power has expanded quickly, and as demand for offshore wind turbines has grown, nacelle design for offshore applications has been continuously improved. The size and mass of the nacelle are also significantly more prominent in offshore turbines because they are typically larger than their onshore equivalents. The core turbine assembly must be safeguarded, most notably by offshore wind nacelles during severe weather events, including cyclonic storms and rogue waves. At the same time, corrosion and other issues may result from the air's high humidity and salt content. 

As a result, offshore turbine nacelles must be manufactured with tighter tolerances and typically use materials suited explicitly for marine environments. The nacelles of offshore wind turbines are among the bulkiest parts of the overall machine. Many other alternative technologies, such as step-up-transformer-less systems, medium-frequency (in the range of a few kHz to MHz) power transformer-based systems, multilevel and modular matrix converter-based systems, and superconducting generator-based systems, have been proposed to achieve a compact and lightweight offshore wind turbine nacelle. Due to the increasing number of offshore wind projects, it is anticipated that the offshore wind markets in China, the US, and Europe will dominate the demand for offshore wind nacelles.

Turbine Capacity Insight

The less than 1.5 MW segment owns the highest market and is estimated to grow at a CAGR of 6.34% during the forecast period. Communities, companies, schools, clinics, single-family homes, farms, telecom towers, and a variety of equipment are often powered by wind turbines under 1.5 MW. Due to their low cost, low maintenance, and dependability as alternative energy generators, small wind turbines up to 0.1 MW in capacity have traditionally been used for remote small off-grid applications across households, farms, agriculture, and telecommunications. They can be installed quickly in a small space without additional infrastructure. 

People are increasingly looking for alternative energy sources due to rising energy costs, the accompanying need for decentralized electricity generation, and worries about climate change, which is driving up demand for wind turbine nacelles in this market. In places where solar power is not practical, small wind power devices, such as transportable micro wind turbines, can be a practical choice for power generation. The movable tiny wind turbines can be quickly deployed and are lightweight. At a wind speed of 18 km/h, it can generate 5 watts of output electricity.

Typically employed for commercial and utility-scale operations, wind turbines with a power output of 1.5 MW to 2 MW are deployed for onshore operations. Per installed MW of nameplate capacity, utility-scale wind turbines cost between US$1.3 million and US$2.2 million. The majority of commercial-scale turbines installed today are 2 MW in capacity and cost between USD 3-USD 4 million to install, according to Windustry. The Global Wind Energy Council (GWEC) estimates that 86.9 GW of installed onshore wind capacity will be added in 2020, reflecting a 59% year-over-year growth that will push the total amount of onshore installed wind capacity above the 700 GW threshold. 

After stagnation between 2016 and 2018, capacity additions started to increase. Onshore wind power generation has a significant cost advantage over offshore power generation. As a result, demand for wind turbine nacelle is expected to rise over the forecast period due to the increasing onshore wind turbine installation worldwide. In Gujrat, the Sulzon firm announced plans to build a 252 MW wind power facility. The project is scheduled to be completed by 2022. The company will install about 120 S120-140m wind turbine generators (WTGs) with a hybrid lattice tube tower and a rated capacity of about 2 MW each.
