Detailed Rationale

CRISIL Ratings has reaffirmed its ‘CRISIL AA+/Stable/CRISIL A1+’ ratings on the bank facilities of Thermax Onsite Energy Solutions Limited (TOESL).

 

The ratings continue to reflect the strong technological, managerial, operational and financial support the company receives from its parent, Thermax Ltd (Thermax; ‘CRISIL AA+/Stable/CRISIL A1+’). The ratings also reflect TOESL's healthy financial risk profile and stable business risk profile supported by long-term contracts providing revenue visibility. These strengths are partially offset by exposure to supply risks for the boilers operated by TOESL.

Analytical Approach

CRISIL Ratings has factored in the business, financial and managerial support received from the parent, Thermax.

Key Rating Drivers & Detailed Description

Strengths:

  • Strong support from the parent, Thermax

TOESL is part of the services vertical of Thermax and receives complete support from Thermax for the maintenance and upkeep of boilers operated by TOESL. The company purchases spares from Thermax and independently finalize contract with customer. Furthermore, financial support from the parent is likely to be forthcoming during exigencies.

 

  • Healthy financial risk profile

Networth is estimated to have been adequate at Rs 139 crore and total debt was Rs 60 crore as on March 31, 2022. Debt is expected to increase to Rs 140 crore in the current fiscal. However, gearing will remain comfortable. Total outside liabilities to tangible networth (TOLTNW) ratio is expected at less than 1.5 times over the medium term.

 

  • Long-term contracts providing revenue visibility

TOESL has long-term contracts with customers. These contracts are typically for 10 years with prices based on fuel price which is pass through with predefined formula. Currently, TOESL has around 28 contracts for supplying, heat, solar and water treatment generated from biomass fired boilers, benefitting its business risk profile. 

 

Weakness:

  • Exposure to supply risks

TOESL takes complete ownership in arranging for the raw material, biomass, used for firing the boilers, exposing it to raw material availability risks. Timely availability of raw material is critical to ensure sustenance of operations. However, this risk is mitigated by the presence of the company’s boilers across India with limited concentration to a geography.

Liquidity: Strong

The parent will continue to provide need-based support during exigencies. On standalone basis, liquidity will remain adequate over the next two fiscals, with net cash accrual expected at Rs 20 crore against debt obligation of Rs 15 crore. Cash and equivalent stood at Rs 10-12 crore and working capital limit was sparingly utilised.

Outlook: Stable

CRISIL Ratings believes TOESL will continue to receive strong support from Thermax over the medium term.

Rating Sensitivity factors

Upward factors

  • Improvement in the credit risk profile of the parent
  • Increase in revenue by more than 15% and stable operating margin over 15%
  • Sustenance of healthy financial risk profile, with TOLTNW less than 1.2 times, and adequate liquidity

 
Downward factors

  • Deterioration in the credit risk profile of the parent
  • Operating margin below 10% because of cost overrun or lack of raw material availability
  • Major, debt-funded capital expenditure or acquisition leading to significant moderation in credit metrics

About the Company

Incorporated in 2009, TOESL operates biomass-fired boilers and supplies steam. It is a 100% subsidiary of Thermax. TOESL procures the boilers from Thermax on lease and installs them in customer locations. While TOESL deploys its workforce to operate and manage the boilers, Thermax provides support in the maintenance of machinery and spare parts.
