    Siegfried Guggenmoos, B.Sc.(Agr.), P.Ag., Principal of Ecological Solutions, Inc. is a Professional Agrologist, with over 30 years of experience in the electric/gas utility corridor vegetation management business.

    Mr. Guggenmoos has designed, implemented and provides assessments of utility vegetation management programs. In evaluating the prudence of vegetation management programs Mr. Guggenmoos has developed methodologies to assess their efficacy by predicting the impact of vegetation management program as practiced, on the future costs and reliability of electric systems.

    Areas of Consultation:
    • Storm hardening electric transmission and distribution systems to quantitatively manage tree-caused service interruptions
    • Advise and develop protocols for assessments of power line tree exposure and mitigation
    • Advise on least cost vegetation management by synchronizing economics and ecology
    • Advise on impacts of vegetation management program alternatives, modifications
    • Provide context for vegetation management, greenhouse gas mitigation measures in a competitive energy market
    • Facilitate for management, staff, contractors and stake holders an actionable understanding of ecological principles and their impacts on vegetation management needs and costs
    • Provide project management; expert review of programs and proposals
    • Develop and advise on quantification, monitoring and verification of biotic greenhouse gas mitigation measures
    Abstract — Severe weather events such as ice and tropical storms routinely cause extensive damage to electrical distribution systems. Much of the damage and service loss can be attributed to trees. Events where service restoration spans days or weeks are generally closely examined through regulator directed hearings. Even when no specific actions are subsequently

    Abstract - For power transmission systems compliant with safety codes and reliability standards there remains a risk of tree-caused interruptions from the in-fall of trees from outside the right-of-way. This paper reports on the quantification of tree exposure outside National Grid’s transmission corridors and examines the variables impacting the risk of a line contact by trees
