| Re: EID - Load Forecast |
| Ramanj -- you raise a perceptive point. In fact, a microgrid is much more "self-aware" than the traditional macro-grad. In the microgrid, there are data from real-time sensors, histories of past loads, predictions of future performance, and algorithms to tie them all together. The transaction software will be prepared to respond, on behalf of the EID, to real-time pricing and demand response requests from the ISO and the utility, and can even provide VAR and frequency support back to the main grid. The macro-grad by contrast can't even tell where a fault is, during an outage. Running the macro-grid has been described as driving down the highway at 60mph, in reverse -- without a rear-view mirror! So the EID's microgrid will be able to report, predict, communicate, and conduct transactions with the ISO, the utility, and anyone else involved with the macro-grad in a more sophisicated and detailed way than they're likely to be prepared to use. |

| Relaying |
| "The macro-grad by contrast can't even tell where a fault is, during an outage." Utilities have been able to locate faults to within 10 feet due to digital relaying... this has been the case for the past decade. The drawback I see is that EIDs won't be able to provide a stable source. So forget EIDs linking a 50 hp motor to their microgrid. The other is variable frequency that is often a problem, especially when dealing with 'information-age' technologies. |

| EID's in the UK |
| I have just spent the past couple of weeks talking to Scottish and English Universities, London Borough Councils, a major UK telecom firm, an FT corrsepondent, etc. about Pareto's EID approach. The response is very positive; especially where major new development is planned & where there is intense pressure to 'green up.' My morning spent with GreenPeace UK left me smiling... |

| EID - Load Forecast |
| Interesting article, customer has choice to draw power from EID or Utility provider based on costs. BUT it would be difficult for utility to forecast/schedule the power requirements to ISOs as customer has choice to choose from EID. How is this being addressed? |
