Gandhinagar Rooftop Solar Project

Country: India

Sector: Solar

Name of Project: Gandhinagar Rooftop Solar Project

Contracting agency: Gujarat State Petrochemical Corporation Limited/ Department of Energy and Petrochemicals

Agency type: Sub-national entity

Type of PPPBOO

Contract term: 25 years

Construction period: -

Bid Parameter: Technical qualification and lowest tariff

Total cost of project: $9 million

Total Population served: 12000

Per unit cost: ~ 19 cents/unit

Basic specifications: Industry best standards are used, government's agreed technical specifications

Stage of project: The agreements were signed in April 2012. The projects are operational

Time taken for processing project from concept to contract execution: 18 months

Local or foreign investor: Local investors, Azure Power and SunEdison

Applicable legislation: Gujarat Solar Power Policy 2009, Gujarat Infrastructure Development Act 1999

Approving authority: Committee headed by the Chief Secretary for approval of PPP projects, Principal Secretary, Energy & Petro Chemicals, Government of Gujarat who is also Chairman cum Managing Director, Gujarat Power Corporation Limited at line Ministry level

Is the approval process the same as for other projects: Yes

Role of Private Party: Procure financing; install solar photovoltaic panels on the rooftops of public buildings made available by government and on private residences and connect to grid; identification of private rooftop space; supply to grid

Role of Public Authority: Provide access to rooftops of public buildings; facilitate Power Purchase Agreement (PPA) with power procurer; monitor contract according to performance standards

Financing: IFC loan of $3 million to Azure Power; other financiers were IDBI Bank, India; financial support of $300,000 was provided by Netherlands and Finland.

Payment Mechanism: The local private power distributor Torrent Power buys the power according to the PPA and pays based on the tariff set through bid.

Tariff: Tariff is based on bid.

Comparison to existing rates: -

Government Support: Facilitation of PPA; public rooftops made available by government

Other advantages: Emissions savings of 6000 tons

Contingent liabilities created: Termination payments- 3 year equivalent of tariff payment in case of Government of Gujarat default.

Risks: Site risk

Level of risk: Low for demand risk as well as site as the public entity covers these adequately as shown under the risk mitigating features

Key risk mitigating features: PPA covers the demand / revenue risk, most of the rooftop sites are public buildings committed to be made available by government

Factors affecting decisions on the size of project or population serviced by the project: This specific project was small, but government has been looking to prepare packages of a size acceptable to the investors. The Gandhinagar project consists of two projects of 2.5 MW each totaling approximately $15 million

Lessons learned:

•  Policy framework is required in order to scale up the projects-the IFC is now working on a policy framework for rooftop solar, regulations are being drafted by the forum of regulators

•  Multiple agreements needed to be signed: rental agreements between private provider and the private residential owners; between the private entity and the public entities owning rooftop space; but there were no standardized documents-for example, appropriate rental agreements for renting rooftop space had to be developed from scratch for this project.

•  Grid connectivity issues needed to be solved and a framework for connecting such projects to grid could be useful

•  Choosing between technical options-in this case the issue was between choosing concentrated solar power or photovoltaic panels

•  Whether gross metering model should be used or the net metering model; there were no specific guidelines for choosing options

•  Multiple jurisdictions can be joined as seen from the efforts to bundle 5 cities into 3 packages for rooftop solar projects in Gujarat following the first success of this specific project.
