Detailed Rationale

CRISIL Ratings has reaffirmed its ‘CRISIL AA-/Stable’ rating on the long-term bank facilities of Green Infra Corporate Solar Ltd (GICSL).

 

The ratings continue to reflect the strong managerial and financial support that GICSL derives being part of the Sembcorp Energy India group. The company benefits from the scale and diversity of assets, strong revenue visibility, and long-term power purchase agreements (PPAs). The ratings also factors in the continued support expected from Sembcorp Industries (SCI), and criticality of Sembcorp Energy India in SCI’s overall business portfolio. Ratings remain constrained by exposure to risks inherent in operating renewable power assets and exposure to merchant prices for 30% of thermal power capacity of Sembcorp Energy India group.

Analytical Approach

For arriving at the ratings, CRISIL Ratings has combined the business and financial risk profiles of Sembcorp Green Infra Ltd (SGIL) and its special-purpose vehicles (SPVs), including GICSL and Sembcorp Energy India Ltd (SEIL). That is because all the entities, collectively referred to as the Sembcorp Energy India group, are engaged in the power generation in India, have a common management, and are all critical to the group. The group has a track record of supporting renewable group entities, and after debt servicing in each SPV, the excess cash flow is largely available for use across the group. (Refer to annexure for a list of the group’s entities).

 

Further, CRISIL Ratings has factored in the support philosophy of the ultimate parent, Sembcorp Industries Ltd, to arrive at the rating of the Sembcorp Energy India group, since it is critical and strategic to the former.

 

Please refer Annexure - Details of Consolidation, which captures the list of entities considered and their analytical treatment of consolidation.

Key Rating Drivers & Detailed Description

Strengths:

  • Management and financial support derived from ultimate parent, Sembcorp Industries:

SCI, currently operating in diverse segments such as energy, water, and urban development, is present across 15 countries. It has capacity of over 13,000 MW of gross power generation, and close to 9 million cubic metre of water treatment per day in operation and under development. With total assets of over SGD 23 billion, SCI is listed on the main board of the Singapore Exchange. It is 49.5% owned by Temasek, a Singapore government-held entity.

 

SCI has supported its assets globally and in India during adverse situations. For instance, it provided support for thermal power assets in India. CRISIL believes the Sembcorp Energy India group is critical to the business of Sembcorp Industries and shall benefit from managerial and financial support from the parent, if required. Any deviation from this will be a key rating sensitivity factor.

 

  • Support derived from being part of the Sembcorp Energy India group

GICSL enjoys strong managerial support from the group. It benefits from the group’s demonstrated track record of execution and ramp-up of projects, and support offered to SPVs in the renewable portfolio, for instance, aid extended to wind power projects on account of stretch in receivable profile of certain projects. The group is likely to maintain adequate liquidity to meet any exigencies or shortfall. Any deviation from the policy of support will be a key rating sensitivity factor.

 

The group derives its strength from its diverse portfolio of commissioned capacity of 2,640 MW thermal power and 1727 MW wind and solar power as of March 2021. It has operational assets in Karnataka, Rajasthan, Gujarat, Maharashtra, Madhya Pradesh, Tamil Nadu, and Andhra Pradesh. Of the total portfolio of 4,367 MW, the group draws strong revenue visibility from long-term PPAs for around 60% of capacity with over nine state distribution companies (discoms), Bangladesh Power Development Board, and Solar Energy Corporation of India/ PTC (apart from various group captive consumers).

 

  • Strong revenue visibility of GICSL

GICSL has 212.5 MW operational wind power projects, spread over Rajasthan, Madhya Pradesh, Gujarat and Maharashtra. These projects have strong revenue visibility, backed by long-term PPAs with state discoms, at tariffs ranging from Rs 4.15/ kWh to Rs 5.92 kWh over the tenor of the agreement.

 

The projects also benefit from generation-based incentive schemes, as they have achieved commercial operations prior to March 31, 2018. Besides this, there is adequate liquidity, for debt servicing during adverse conditions, to be kept as a part of the transaction in the form of one quarter DSRA (debt service reserve account).

 

Weakness:

  • Exposure to risks inherent in operating renewable projects

Cash flows of renewable power projects are sensitive to the plant load factor (PLF), which depend entirely on wind and solar patterns that are inherently unpredictable. This could impact the group’s debt servicing capability.

 

  • Exposure to counterparty risk and merchant price movements for thermal power unit

The Sembcorp Energy India group has 2,640 MW of coal-based thermal power plants. It has long-term PPAs for 1,320 MW, on net generation basis, of this capacity. Sale of power generated from the balance untied capacity on a short-/medium-term basis, exposes this capacity to volatility in merchant rates. Until the capacity gets tied up in a long-term PPA, quantum of power sold at a rate exceeding the variable cost of generation, will remain a key monitorable.

 

A large proportion of the long-term PPAs for thermal power capacity are with discoms of Andhra Pradesh and Telangana, and with Bangladesh Power Development Board. The group has been managing any irregularities in payments from any of the counterparties for thermal capacity through working capital bank debt. Though implementation of the payment security mechanism by way of issuance of letter of credit (LC) should benefit power generating entities, including the Sembcorp Energy India group, the extent of the benefit and its impact on the receivable position are monitorables.

Liquidity: Strong

The Sembcorp Energy India group has strong liquidity. Cash flow available for debt servicing is projected at over Rs 3200 crore over fiscal 2022, against yearly long-term debt obligation (including principal and interest payment) of around Rs 2,000 crore in fiscal 2022. CRISIL believes the Sembcorp Energy India group has sufficient liquidity to cover its debt obligation, with consolidated cash levels of above Rs 1000 crore as of September 2020. Further, support can be sought from SCI, if required. Additionally, for the thermal projects, fund-based limit was utilised at an average of about 75% for project 1 and around 45% for project 2 during the twelve months through February 2021. Equity portion of investments of around Rs 600 crore in fiscal 2021 and 2022 is expected to be met out of accruals and cash balances.

Outlook :Stable

CRISIL Ratings believes GICSL will sustain its credit profile over the medium term, backed by steady growth in revenue and profitability, continued support from the Sembcorp Energy India group, and better operating performance of the consolidated Sembcorp Industries group.

Rating Sensitivity factors

Upside factors

  • Improvement in the credit profile of Sembcorp Energy India group
  • Commissioning and ramp up of renewable portfolio of Sembcorp Energy India group’s under-construction portfolio, such that more than 75% of the portfolio outperforms the P90 PLF on a sustained basis

 

Downside factors

  • Weakening of credit quality or support philosophy of Sembcorp Industries towards the Sembcorp Energy India group
  • Pressure on GICSL’s credit quality, owing to sustained weaker than P90 performance or stretch in receivables

About the Company

GICSL is a majority held subsidiary of SGIL that has a portfolio of 212.5 MW operational wind power projects. These projects are spread across states of Rajasthan, Madhya Pradesh, Gujarat and Maharashtra.

 

SEIL was incorporated in 2008, as Thermal Powertech Corporation of India Ltd, as an independent power producer in India. Sembcorp Industries (a Singapore-registered company) through Sembcorp Utilities, acquired a controlling stake in July 2014. SEIL has a portfolio of 2640 MW operational coal-based thermal power plants in India.

About Sembcorp Industries

Sembcorp Industries, 49.5% owned by Temasek, is a leading energy, water, and urban development group operating across five continents. It has around 13,000 MW of gross power capacity and close to 9 million cubic metres of water treatment per day in operation and under development.
