Project Highlights

Larry has served in lead or management roles in a wide range of audit engagements for 13 regulatory commissions, involving 19 electric utilities and 6 gas utilities. His roles have included reviews of planning and budgeting, workforce management, human resources, fuel procurement, executive compensation, mergers, service and holding company support for utility operations, and affiliate relations and transactions.

Larry served in a managing role on four management and operations audits of natural-gas distribution utilities for Liberty, serving the public-service commissions of Connecticut and Arkansas. He served as project manager on many of them.

Larry also has broad experience in conducting commission-sponsored audit engagements of local-exchange providers. He has served in a lead role on Liberty’s audits of Verizon (or predecessor) operations in New York, Pennsylvania, New Jersey, Maryland, the District of Columbia, New Hampshire, and Kentucky.

Larry managed Liberty’s off-shore re-engineering project for an electricity system in Central America and he performed cost and best-practices benchmarking in Liberty’s work for an Ohio electricity and gas supplier and a major southern electricity generation and transmission cooperative. He also performed cost-reduction studies in energy procurement, transmission and distribution, and human resources for an electric-utility holding company and a natural-gas utility.

Larry examined a variety of ratemaking and economic aspects of telecommunications diversification by a New England electricity supplier. He also managed a Liberty engagement designed to assist a client in assessing its competitive strengths and weaknesses in competing in utility energy-supply markets.

He also served in management or lead-consultant roles in two projects for a public-service commission in monitoring an electric utility’s divestiture of its nuclear and fossil-fueled power plants, two projects for commissions that considered the mergers of electric utilities, a study of a telephone company’s achievement of projected merger savings, and an evaluation of an electric utility’s decision to build a new power plant.

A substantial amount of Larry’s work has been in the area of assessing the propriety of the relationships between utilities and their non-regulated affiliates. He has had leadership roles in assignments in this field on electric, natural-gas, and telephone utilities, including Verizon companies four times and five electric utilities.
