Wind Solar Hybrid projects

What if we told you that the average clean renewable energy delivered to large corporates can be increased by integrating wind and solar farms to provide a hybrid supply. Wind Solar Hybrid presents an opportunity to harness the complementary nature of solar power and wind power.

A Wind Solar hybrid plant generates power in a continuous pattern, with much less variability than a standalone solar plant (generates only during daylight hours) or standalone wind plant (generates mainly during evening/night).

The Wind Solar Hybrid solution ensures high Plant Load Factors (PLFs) and offers a highly efficient as well as stable energy source.


What is Wind Solar Hybrid (WSH):

The Hybrid power system combines power from solar panels and wind turbines to produce uninterrupted electric power, and the combined supply is wheeled by CleanMax to your respective facilities in a pattern that matches your base load.

Solar and wind power plants share the same evacuation infrastructure; hence the fixed costs and transmission charges are lowered and also the power becomes less susceptible to curtailment because of its regular generation pattern.

Corporates can utilise the non-intermittent power they need, equivalent to their base load, and pay for only power used, at tariffs lower than prevailing grid electricity tariffs.

* Example:

The below graph showcases the benefit of procuring power from the Wind Solar Hybrid Farm.

Let’s assume that this large corporate has a need for continuous & constant power load of 100 units throughout the year 24x7.

In this example, power procurement through solar plant alone can only cater to 60 units i.e. for every 100 units of electricity required only 60% of power can be substituted by Solar , while wind alone can only cater to 50 units i.e. for every 100 units electricity required only 50% of power can be substituted by Wind.

But the power procurement through a Wind Solar Hybrid farm can supply up to 75 units i.e. for every 100 units of electricity required 75% of the power requirement can be substituted by Wind Solar Hybrid Farm with little to no reliance on banking. In this example, the customer can achieve around 30% savings on their annual electricity bills versus 20% to 25% from wind or solar alone, due to the larger proportion of power supplied.

Frequently Asked Questions

A typical rooftop solar power plant may not be able to meet the substantial power demands of corporates due to space constraints. This is where utility-scale grid connected Open Access plants come in, which enable greater renewable power generation
Typically, two procurement models are used: third-party PPAs and captive or group captive models
Open access charges under a utility-scale renewable project vary with location and procurement models. Various charges under the Open Access mechanism include the following:
  • Transmission charges
  • Wheeling Charges
  • Transmission losses
  • Wheeling losses
  • Cross-subsidy surcharge (CSS)
  • Additional surcharge (AS)
  • Banking charges
  • Due diligence based on company locations
  • Understanding Open Access Risks
  • Due Diligence on the developer
  • PPA Negotiations

Contractual Challenges:

  • Tenor mismatch between PPA & loan
  • Contract enforcement
  • Contract standardization

Operational Challenges:

  • Grid curtailment risk
  • Performance risk

Regulatory Challenges:

  • Uncertainty around Open Access regulations and charges
  • Inconsistency in eligibility and operating criteria for Open Access
  • Exclusion from Open Access
  • The utilities point of view
  • Paper-based approval process

This is how Captive works:

In the captive capex model, the corporate buyer for a utility scale renewable project makes the upfront capital investment. The buyer owns the power generating asset and the solar power generated is used for the corporate buyer’s self-consumption. CleanMax constructs the plant and operates and maintains it over its lifetime.

Benefits

Hedge against electricity charges
Open Access charges from the grid are applicable, but unpredictable charges, such as cross-subsidy surcharge and additional surcharge, are waived off in captive and group captive projects.
Tax benefits
Under this structure, a corporate buyer who holds the asset on its balance sheet is also eligible to claim tax benefits through accelerated depreciation.
No technical experience needed
CleanMax will provide complete turnkey EPC solution while commissioning the plant with necessary regulatory approvals and due diligence. In addition, CleanMax will also operate and maintain the plant over its lifetime of 25 years.

Frequently Asked Questions

The corporate buyer must hold at least 26% of the equity while the developer arranges for the rest 74%. A Power Purchase Agreement (PPA) can be signed on mutually agreed terms between the developer and the buyer. In such a project, the O&M responsibilities are usually passed on to the developer

The corporate buyer should ensure that a Group Captive project is fully compliant with the spirit of the law, and with the Electricity Act and the proposed amendments to the Electricity Rules by following two simple guidelines:

  • Equity participation: A genuine equity contribution, equal to 26% of the equity cost, assuming 70/30 debt to equity ratio
  • Economic participation: Which means paid up equity share capital with full rights such as, value, share of profit/dividends, capital appreciation, voting rights, transfer of shares etc. should be applicable for all shareholders
Given the regulatory requirement for the lead captive buyer to own a minimum of 26 percent of the power generating plant, ownership must be transferred to another captive buyer or back to the primary investor if the PPA terminates or expires. Parties typically agree to a put/call option structure to transfer the shares upon expiry/termination of the PPA. If either the captive generator or the buyer is a non-resident or foreign-owned and controlled entity, then subscription/purchase of equity shares as well as subsequent transfer must comply with the Reserve Bank of India’s pricing guidelines.

This is how Group Captive works:

A variant of the captive model is the group captive model. Under the group captive model, a project is developed for the collective usage of one or many corporate buyers. CleanMax sets up a Special Purpose Vehicle (SPV) for group captive wherein the corporate buyer(s) holds only 26 percent of equity in a project and needs to collectively consume at least 51% of the power with the PPA. Here too, CleanMax will take complete responsibility for building, operating, and maintaining the project.

Benefits

Minimum investment and risk
The corporate buyer can avail open access benefits of a group captive project without being required to completely own the project. Here, CleanMax will bear 74% of the investment – with the corporate buyer holding at least 26% equity. This is done to meet the ownership criteria that will allow exemption of cross-subsidy surcharge.
Guaranteed savings on electricity
Even though the user is required to purchase electricity from CleanMax through a Power Purchase Agreement (PPA), it comes at much lower rates than prevailing grid tariffs, resulting in guaranteed savings on every unit consumed.
