2. Connection Charges
Current Philosophy
• Connection charge (shared assets)
= R/kVA charge * project MEC
• R/kVA charge = [Cost of shared assets] /
[installed capacity of equipment]
• All connections considered « equally »

2. Connection Charges
Current Philosophy
• No consideration for:
• Project location
• Existing minimum load
• Existing equipment (where no upgrade required)
• Opportunity to optimise generators’ location on network by
incentivising projects that:
• Reduce network losses (by reducing load)
• Improve network stability
• Delay or avoid need for network upgrades
• Can connect faster (by using existing infrastructure)

3. Business Models for RPPs
Centralised – Single Buyer

• E.g.: REIPPP
• Pros:• Bankable• Low IPP risk• Lowest tariffs
• Cons:• Central procurement• Possible conflict
(utility = buyer)

(optional)
• E.g.: Rooftop, mines…
• Pros:• Easy / quick to deploy• No network charges• Enabling legislation
• Cons:• Site limitations• High offtake risk• Higher LCOE• Difficult to regulate• No network charges

• E.g.: Google datacenters
• Pros:• Low LCOE• PPAs don’t sit with utility• Tolling fee for utility
• Cons:• Network charges• Regulatory framework

3. Business Models for RPPs
Conclusion
• Different models serve different purposes and technologies
• Diversity = risk management
• Wheeling = risk shifted from utility to the IPP / C&I offtaker
• Need to update regulatory framework to ensure wind isn’t excluded
from IRP embedded generation allocations (200MW / annum)
• Grid codes / rules need to align with RE policy objectives
