Management Reports


Cost of Service Rate Study

A detailed cost of service study will include allocating the operating and maintenance expenses and the cost of gas supply to each classification of retail customer. Financial statements for the previous years will be reviewed. Cost of administration, debt service, etc., will also be allocated to each rate classification. A financial model will be created to analyze various scenarios. The model can be used to evaluate changes in the number of customers, consumption patterns, weather sensitivity, and the proposed rates among other variables. Considering the impact to each customer classification, a rate adjustment may be recommended. Appropriate data will be analyzed and alternatives will be presented to management. Final results will be effectively communicated and graphically presented in the Cost of Service Rate Study Report.


Expansion Planning Study

Expansion planning studies include identification of areas of expected growth, preliminary system layout and construction costs, forecast of new customer connections, and an economic analysis of each targeted area. Potential expansion areas are examined on an individual project-by-project basis. Recommendations are summarized and capital spending plans developed to address the client's planning and budgeting needs.


Natural Gas Supply and Load Studies

The usage characteristics of a system are developed and correlated to climatological data to establish load requirements. Future load requirements as a result of system expansion and the connection of new customers are incorporated into the forecasting horizon. The load characteristics developed assist the client with daily dispatching, monthly purchasing requirements, and annual budgeting. An analysis of the system's gas supply contract and peak shaving facilities is conducted to determine optimum levels of peaking service and establish interstate/intrastate pipeline contract limits/options.


Distribution System Flow Analysis

The transmission and distribution system can be modeled with computer software to analyze the pressures and capabilities of any segment of the system. Loads are assigned to nodes within the network of pipelines by reviewing client sales records. The model is verified by incorporating historical operating conditions. The computer model enables the system to be optimized and the effect of future expansion/loads can be predicted.

CNG Vehicle Feasibility Study

Client's fleet can be analyzed to determine the economics for conversion to CNG powered vehicles and the construction of a CNG fueling station. The optimum location and type (fast or time fill) of fueling station can be determined along with a schedule for capital expenditures to efficiently utilize natural gas for vehicle fueling.


Cast Iron System Maintenance and Replacement

Cast iron system maintenance and replacement studies address the ongoing maintenance and safety concerns of operating distribution systems containing cast and ductile iron pipe. Heath and Associates identifies the condition of the client's cast iron system piping by researching records and developing statistical operating histories. The cast iron piping is categorized, evaluated, and ranked to develop recommendations regarding maintenance or replacement. Replacement cost and construction methods are addressed and capital improvement plans are developed.


Comprehensive Planning Study

A comprehensive planning study (or master plan) can be developed incorporating the cost of service rate analysis, expansion planning, natural gas supply and load study, and system distribution flow analysis. The comprehensive planning study can also address system operating statistics, record keeping, organization and compliance requirements, suggest a marketing plan, and develop a gas purchasing policy. The comprehensive planning study, basically, can be tailored to include and address any aspect of the operation and management of the system.
