Target Support. Adaptive Policies
Certainty: No discretionary decisions in the permitting chain.
Predictability: Every process must have a deadline and defined roadmap.
Structured: Who does what, under what criteria, in how much time.
Simplicity: Clean stepped process with no back loops.
Attractive: Market, participation mechanics and incentives.
Transparent: All processes must follow public known guidelines.
Sustainable: Predictable growth in market size and price.

Streamlining Solar Projects. Increasing Efficiency
14
• Minimize construction time with “building blocks” manageable with available resources
• Integrate your partners and suppliers in the opportunity evaluation and project design
• Create your own “flexible standards” to optimize procurement & capacity
• Minimize maintenance requirements & account for remoteness
• Select components that minimize the potential break points
• Develop a pipeline of projects to maximize your buying power
• Start the permitting for the next opportunities as they become available
• Select key equipment based on its capacity to support the particulars of the grid
Main Areas in the Feasibility Study of Solar PV Projects
• From developer’ perspective:– Legal environment.
– Market size and participation options.
– Permitting process & technical regulations.
– Payback terms and guaranties.
– Grid capacity – Systems size.
– Viable interconnection options.
– Site options and conditions.
– Logistics & equipment available.
– Labor and specialized contractors.
– High level EPC & OM programs and costs.
– Financial model.16
• From PLN perspective:
– Analysis of proposed grid area for connection.
– Grid capacity vs Systems size,
• Existing generation.
• Existing loads.
• Feeders capacity & load.
• Planned increases in generation & load.
• Flow & load analysis (on developer).
– Viable interconnection options (near site tower, new derivation, new switchgear in
substation).
– Technical Specifications for interconnection.
