Frequently Asked Questions

Small wind energy refers to wind turbines installed at lower heights, typically between 15 to 30 meters, designed to generate electricity for on-site consumption. In India, especially in coastal regions like Gujarat, small wind turbines can operate efficiently at wind speeds as low as 3.5 m/s, making them suitable for industrial and commercial applications without requiring large infrastructure.

Gujarat is one of the most suitable regions in India for small wind energy due to its 1,600 km coastline and consistent wind speeds above 5.5 m/s. According to the National Institute of Wind Energy, the state has strong wind potential at lower hub heights, making it ideal for decentralized energy generation.

Solar energy generates power only during daylight hours, while wind energy can generate power throughout the day and night. For factories operating multiple shifts, wind energy complements solar by providing electricity during evening and night hours, resulting in a more balanced and reliable energy supply.

Solar power alone cannot efficiently support a 24/7 factory because it does not generate electricity at night and its output decreases during monsoon periods. Factories with continuous operations require a hybrid approach, combining solar with wind energy to ensure consistent power generation.

A wind-solar hybrid system combines both energy sources to maximize power generation. Solar produces energy during the day, while wind generates power during night hours and monsoon seasons. This complementary generation increases the overall capacity utilization factor and improves return on investment.

Capacity Utilization Factor (CUF) measures how efficiently an energy system generates power compared to its maximum possible output. A higher CUF indicates better performance and higher energy output. Hybrid systems in Gujarat can achieve CUF levels of 35 to 40 percent, significantly higher than solar-only systems.

Industries in Gujarat can reduce electricity costs by ₹3.50 to ₹5.00 per unit by switching to wind or hybrid systems. For a typical manufacturing unit, this can result in annual savings of ₹20 lakh to ₹40 lakh depending on energy consumption and system size.

The average cost of installing a small wind turbine in India is approximately ₹80,000 per kW. Although this is higher than rooftop solar, the higher energy output and better CUF make wind energy more cost-effective over the long term.

Wind energy projects qualify for accelerated depreciation under Section 32 of the Income Tax Act. Businesses can claim up to 60 percent depreciation in the first year, significantly reducing taxable income and improving project returns.

A PMA direct-drive wind turbine uses a permanent magnet alternator and does not require a gearbox. This reduces mechanical failures, improves reliability, and increases uptime to over 98 percent, making it more suitable for industrial applications.

Yes, renewable energy projects can be financed through structured loans covering 70 to 80 percent of the project cost. Many financial institutions in India offer green financing, and the energy savings generated by the system often cover loan repayments.

The payback period for a wind-solar hybrid system is typically under four years, depending on system size, energy consumption, and financing structure. Accelerated depreciation and rising grid tariffs further improve returns.

Electricity tariffs in Gujarat have been increasing due to rising fuel costs, infrastructure investments, and regulatory adjustments. The average annual increase is around 5 percent, which significantly impacts long-term industrial operating costs.

Delaying installation results in lost savings due to rising electricity tariffs. Each year of delay can cost industries ₹5 lakh to ₹8 lakh in unrealized savings, which cannot be recovered later.
