My background in computer manufacturing and engineering has opened my eyes to the absence of defined professional systems’ architecture for the integration of wind power in Maine. To ensure system cost advantages and operational excellence, an architecture must be in place to define the interconnections of all system components and sub-systems, including the consumers.

Similar to computer engineering, in the electric power systems definition, there are major system building blocks and interoperability standards. When new technology subsystems are introduced, new standards and a revised system approach must also be introduced. It seems the current system needs significant re-engineering to deliver the promise of lower electricity costs to consumers.

The following must be integrated:

Current electric supply generator businesses (hydro, bio-mass, natural gas, nuclear); future generator businesses (wind, solar); NE-Grid or a replacement; CMP delivery systems; new and existing transmission lines; and consumers’ needs. 

News reports indicate significant potential change to the Maine electric power system: Hydro Quebec penetration, billion-dollar transmission lines, micro-grid funds to CMP, Northeast grid performance issues, political pressure advocating wind as a primary source of power.

Only excellent system design will deliver lower costs to consumers. We’re not ready yet! We need answers to our concerns. Please vote in Rumford on Dec 3. for the wind power moratorium on new developments to provide time for learning before acting.
