Sunsure Energy and Wonder Cement Finalize Solar Power Purchase Agreements

Agreement Overview

Sunsure Energy and Wonder Cement have formalized three consecutive long-term solar open-access Power Purchase Agreements (PPAs) representing a total renewable energy capacity of 30 MWp. These agreements possess a 25-year weighted average duration, providing a stable multi-decade framework for the offtaker’s energy procurement strategy.

Structurally, the power is sold under the “Group Captive” mechanism. This regulatory arrangement is technically significant as it exempts the offtaker from the Cross-Subsidy Surcharge (CSS) and Additional Surcharge (AS), which typically inflate the landed cost of power. By bypassing these surcharges, Wonder Cement achieves heightened tariff competitiveness and secures long-term price certainty below current grid-parity levels.

Project Locations and Logistics

The power generation is facilitated through Sunsure’s utility-scale assets in Maharashtra and Uttar Pradesh. To streamline financing and operations, the partnership utilizes the Special Purpose Vehicle (SPV) Sunsure Solarpark Twenty Six Private Limited. This SPV is a ring-fenced entity that specifically operates an 8 MW AC (12 MW DC) solar project in Maharashtra dedicated to this arrangement, ensuring asset pooling and financial transparency for the stakeholders involved.

Sustainability Metrics and Electricity Displacement

The cement industry is categorized as a “hard-to-abate” sector, where approximately 60% of emissions originate from the calcination process and 31% from fuel combustion. These PPAs specifically address the remaining 9% of emissions associated with electricity consumption. By transitioning to solar open-access, Wonder Cement is making a measurable impact on its electrical decarbonization pillar.

The Uttar Pradesh integration at the Aligarh facility is particularly noteworthy, as it aligns with the state’s emergence as a solar open-access hub driven by the expansion of data centers and the developing “defense corridor.”

Reported sustainability metrics include:

• Annual CO2 Emission Reduction: 33,000 metric tonnes (cited as equivalent to the carbon sequestration of 1.5 million trees).
• Electricity Displacement (Dhule, Maharashtra): 67% of the facility’s total power consumption.
• Electricity Displacement (Aligarh, Uttar Pradesh): 52% of the facility’s total power consumption.

These figures support Wonder Cement’s broader goal of integrating renewable energy across its total manufacturing capacity of 21.5 MTPA.
