a) Statutory approvals:
The client to ensure that; all and/or any statutory approvals related to the setting up and functioning of the Solar Power Plant are in place in a timely manner.
Any delays in getting the required approvals or because of any issues related to these statutory approvals will be the responsibility of the client, and these delays may impact the project schedule accordingly.
Tentative activity schedule is attached below. However, this is subject to getting timely approvals (in Client’s scope of work) on Plant layouts, civil drawings, Electricity board approvals, Power evacuation approvals, etc.

b) Project Implementation Strategy:
It is envisaged that the project will have the below mentioned phase of activities. These phases are not mutually exclusive; to implement the project on fast track basis some degree of overlapping is envisaged.
☛ Phase-I : Project Development
☛ Phase-II : Finalization of the Technology Provider and Supply Contract
☛ Phase-III : Procurement and Construction.
☛ Phase-IV : Plant Commissioning

Phase I – Project Development
In a power project, development of the project plays an important role. Almost 50% of the work is done if one achieves power purchase agreement from the respective state utilities. The project development starts with visits to the region, understanding about the regional conditions, socio economic conditions, transportation facilities and infrastructure facilities available in the region.
Apart from the above, the below listed tasks will be under project development:
☛ Preparation of Detailed Project Report (DPR) (2 weeks)
☛ Submission of DPR for state approval (complete)
☛ Power purchase agreement (PPA)/ E P C C o n t r a c t
☛ Procure Central Regulatory Authority clearance
☛ Procure Forest Clearance
☛ Procure Pollution Control board clearance.
☛ Procure Industries departmental clearance.
☛ Procure Irrigation department clearance.
☛ Land Identification & procurement (Responsibility of Client)
During this phase, a Project team will be formed for the execution of the project. The responsibilities of the project team shall be: Planning and programming of all the resources required for project completion Inspection of major fabrication items
☛ Organize the construction and commissioning of the plant
☛ Monitoring and controlling the project progress
☛ Execute the project within the planned budget

Phase II – Finalization of the Technology Provider and Supply Contracts
In the power plant, modules and junction boxes are the lead items and the planning schedule for the project implementation should provide adequate time period for the procurement and installation of these equipments. The specifications for major equipment shall be drawn up at an early stage of the project. Program of design information, from the equipment suppliers, that satisfies the overall project schedule shall be drawn up. Since, the project execution calls for closer coordination among the contractors, consultants and the company, proper contract co-ordination and monitoring procedures shall be made to plan and monitor the project progress.

Phase III – Procurement and Construction
The Procurement is an important function of the implementation of the project. Once the purchase order is placed, the project team follows up regularly to ensure smooth and timely execution of the contract and for obtaining technical information for the inter package engineering. The procurement activity includes review of drawings, expediting, stage and final pre delivery inspection, supervision of installation and commissioning. During Construction, the erection and commissioning phase of all the contracts proceed simultaneously. Adequate power and water shall be made available for the construction. Construction manager (Project Coordinator) takes the overall responsibility of the site.

Phase IV- Erection and Commissioning Phase
The commissioning phase in a project is one where design, manufacturing, erection and quality assurance expertise are put to test. The commissioning team will be from manufacturer of the equipment, consultant and the company. Staff identified to operate the plant will also be involved in the commissioning phase of the project itself. When construction phase is complete, the check list to be designed to ensure that the plant has been properly installed with appropriate safety measures. The commissioning team will follow the internal operating instructions. The plant shall be subjected to a performance test.

c) Timeline for Clean Development Mechanism
Clean Development Mechanism (CDM) has a huge gestation period and Powerwin CDM team start working on it after client gets state approval for Detailed Project Report. It will take 12-18 months to complete the whole CDM registration process.

Scope of Work Estimated Completion Period

Preparation of Initial Assessment report development 4-6 weeks from signing of a CDM agreement

Preparation of PIN & receive any Outstanding information 1-2 weeks following

Preparation of CDM, PDDs & organization of an on-site stakeholder consultant 4-6 weeks following

Host country approval process 4-6 weeks following

Validation & Registration process 30-40 weeks following
