SmartGrid Considerations (cont.)
Own Rent
• Capital expense • Low capital, pay-as-you-go
• High reliability • Less reliable
• Utility controlled - coverage, capacity, priority, security
• Limited visibility, no control over coverage, capacity, priority, security
• Cost effective for multi-use • Limited economies of scale
