Guidebook for Demand Aggregation: Way Forward for Rooftop Solar in India Analysis and Summary

This guidebook by the Asian Development Bank (ADB) details the demand aggregation and utility-driven business models to accelerate rooftop solar (RTS) adoption in India. Here's a structured summary:

Core Objective

India aims for 175 GW renewable energy by 2022 (including 100 GW solar, 40 GW via RTS). Despite enabling policies and falling costs, RTS deployment has been slow (6.476 GW as of Feb 2022). The guidebook proposes demand aggregation as a solution to scale RTS through innovative models, leveraging utilities' roles.

Key Findings

1. Business Models:

   • Facilitation Approach: Utility aggregates demand and facilitates installation (no investment).
   • Investment Approach: Utility invests, owns, and operates RTS systems via "right-to-use" leases.
   • Four sub-models under utility-driven aggregation: Consumer-owned, Utility-as-EPC, Third-party owned, and Utility-owned.

2. Policy Support:

   • MNRE Phase II Guidelines: Utilities as primary implementers, central financial assistance (CFA), and incentives tied to installation targets.
   • State Programs: e.g., Gujarat’s SURYA scheme, Kerala’s Soura Project, and Delhi’s rooftop solar policies with subsidies and demand aggregation tenders.

3. Benefits:

   • Utilities: Reduced losses, revenue stability, economies of scale.
   • Consumers: Lower costs, simplified processes, quality assurance.
   • Developers: Streamlined approvals, assured off-take, reduced transaction risks.

4. Challenges Addressed:

   • Policy uncertainty, high transaction costs, financing gaps, and developer selection challenges are mitigated through demand aggregation.

Implementation Steps

The guidebook provides a phased approach:

1. Prelaunch Planning: Capacity building for utilities, team formation, and technical assessments.
2. Consumer Enrollment & Site Feasibility: Data collection, roof assessments, and aggregation.
3. Bidding & Contracts: Transparent tendering, vendor selection, and regulatory filings.
4. Installation & Monitoring: Post-installation performance tracking under investment models.

Key Recommendations

• Demand Aggregation: Utilities must adopt systematic approaches to reduce costs and risks.
• Technology & Tools: Use LiDAR, drones, or satellite data for accurate potential assessments.
• Marketing & Outreach: Raise consumer awareness through campaigns and partnerships.
• Policy Advocacy: Streamline regulatory approvals (e.g., SERC filings) to enable new business models.

Conclusion

Demand aggregation frameworks enable scalable RTS deployment, aligning utility interests with consumer and environmental goals. By 2030, India’s 500 GW target underscores the urgency to adopt these models. The guidebook serves as a practical roadmap for utilities, developers, and policymakers.
