Simplex Castings Advances Green Energy

Transition with 25-Year Solar Power Agreement

Company enters long-term captive solar arrangement with Natraj Energy; annual energy and

power cost to be saved upto approximately ₹2.16 Crores

Bhilai, 8th June, 2026: Simplex Castings Limited (BSE: 513472), India’s leading precision

metallurgy and casting solutions company, has entered into a 25-year Power Purchase

Agreement (PPA) with M/s Natraj Energy, a Raipur-based renewable energy partnership

firm, for the supply of clean energy through a captive solar power project under the Long-

Term Open Access (LTOA) mechanism in the State of Chhattisgarh.

Under the agreement, Natraj Energy will develop, own, operate and maintain a 5.5 MWp grid-

connected solar power plant, which will supply renewable electricity to Simplex Castings'

manufacturing facilities at Bhilai and Tedesara through the open-access captive

consumption mechanism.

The transition to solar power is going to deliver annual energy cost savings of close to ₹2.16

Crores, representing a significant improvement in the Company's cost structure over the life

of the agreement. Prior to this arrangement, the Company was sourcing power at ₹9 per unit

from the conventional grid. Under the new solar power agreement, Simplex Castings is

expected to achieve a saving of close to ₹3 per unit, effectively bringing its net energy cost

down to ₹5-6 per unit for the same consumption pattern.

The arrangement has been structured on a cash-neutral basis, enabling the Company to

participate in the project economics without material upfront capital outlay.

Natraj Energy will assume full responsibility for project development, statutory and regulatory

approvals, grid connectivity, long-term open access arrangements, and operations and

maintenance of the solar facility throughout the 25-year term. The agreement incorporates

robust performance and payment security mechanisms to ensure reliable energy supply to the

Company.

Commenting on the development, Mr. Ketan Shah, Chairman and Executive Director

said: stated: “This long-term solar power arrangement marks a significant step in Simplex

Castings' sustainability journey. By securing clean energy at a predictable tariff over a 25-year

horizon, we are simultaneously strengthening our commitment to responsible manufacturing

and meaningfully improving our energy cost structure. The annual savings of approximately

₹2Crores reflect the tangible financial value of this initiative which adds to our margins,

alongside its environmental benefits. We look forward to a productive partnership with Natraj

Energy as we work towards a cleaner and more efficient future.”
