New Telecommunications Media Alternatives for Utility Automation Applications |  Rick A. Schmidt, Power System Engineering, Inc.
Most utility automation programs require a communication infrastructure to facilitate the transport of data from a fixed site in the field to a central operations center. This presentation reviews the leading technologies for common utility automation programs. Some of the communication technologies reviewed include third generation commercial cellular, VSAT Satellite, licensed and unlicensed radio, and 802.11 b. |

Wireless SCADA - Beyond the Substation | Rick A. Schmidt, Power System Engineering, Inc.
Utilities are establishing real-time communications with their line device sites beyond their substations. Monitoring reclosers, switches, capacitor banks, and other line device sites is becoming quite feasible for many electric utilities. In this presentation, various communication media alternatives for line device monitoring are reviewed and discussed along with eight real-life case study experiences of small, medium, and large utilities. |

Carbon Impacts on Capacity and Generation Mix | Duane T. Kexel, Power System Engineering, Inc.
In response to the Kyoto Protocol, reduction of carbon emissions has become an intensely debated international topic. The weight of the scientific evidence indicates that global warming is likely to continue and that the economic consequences would be large. While opinions vary widely on the appropriate market and regulatory interventions to address this problem, most agree that the costs to mitigate will rise substantially as interventions are deferred. This paper assesses the impact of carbon taxes and a coal moratorium on utility selections of an optimum capacity mix and on planned dispatch of units. This paper was originally presented at the 2001 PowerGen Conference. The Power Point presentation is also available upon request. |

Safety, Reliability, and Service Quality | Douglas R. Larson, Power System Engineering, Inc.
Safety, Reliability and Service Quality (SRSQ) is receiving increased attention in states under-going restructuring as well as in areas where customers or others have questioned the reliability or service performance of specific utilities. This presentation summarizes the development of SRSQ rules recently implemented in the State of Minnesota. |

Line Extension | Douglas R. Larson, Power System Engineering, Inc.
Line extension policies and charges are a means of ensuring that utility investments on behalf of a single customer are fair and reasonable. The Line Extension Workshop has 3 primary objectives as follows:
- Provide an overview and background information for relevant context on line extension policies and charges;
- Review line extension policies and charges for investor-owned utilities in Minnesota; and
- Outline and describe the process for cooperative analysis, review and implementation of extension policies and charges.
To accomplish these workshop objectives, the line extension workshop covers the following topics:
- Perspectives on line extension charges;
- Policy considerations;
- Regulatory considerations;
- Legal considerations;
- Investor-owned utility tariffs; and
- Developing and implementing line extension policies and charges.

The first half of this presentation covers the following DG rate issues as discussed by the DG Rate Work Group formed by the MPUC:
- Which customers qualify for DG rates;
- Description of utility supplied services;
- Principle for setting rates for services provided by DG customers to utilities;
- Principle for setting rates for services provided by utilities;
- Calculation of avoided costs;
- Standby rates; and
- Credits.
The other half of this presentation covers technical requirements and other information included in the following five documents developed by the DG Technical Work Group formed by the MPUC:
- Interconnection Process;
- DG Interconnection Requirements;
- Application;
- Engineering Data Submittal; and
- Agreement.

| CDM Consolidated Methodology for Electric Sector Baselines – Issues and Proposed Answers | | Duane Kexel of PSE was retained by the Carbon Finance Business (CFB) of the World Bank to present his assessment of major issues and proposed solutions in developing baselines for electric grid displacement projects under the Clean Development Mechanism (CDM) authorized by the Kyoto Protocol. The CDM Methodology panel has approved several methodologies for such baselines including the most recent consolidated methodology which argues for equal weighting of the operating margin and the build margin and heavy reliance on historical data for estimation of these margins. However, the Methodology Panel has not had adequate support or staffing to respond in a timely fashion to the numerous questions raised about appropriate baselines for grid displacement projects across the world.
CFB sponsored the workshop in Buenos Aires to coincide with the Conference of Parties to the Kyoto Protocol to bring project sponsors, carbon purchasers, and the CDM regulators together to discuss their common interests in development of transparent and practical baseline methodologies that assure the integrity of the CO2 emission reductions that are claimed.
Mr. Kexel’s presentation characterizes the challenges faced by the CDM panel in trying to meet the requirements for legitimate reductions without unduly retarding the development of carbon markets. He then proposes a variety of simple but reasonable methods for baseline development based on his experience in creating a standardized methodology for grid displacement projects in the Czech Republic. Following this workshop, Mr. Kexel is preparing a paper that summarizes the findings and recommends a future research agenda that will advance the pace and accuracy of baseline development over a broad range of power systems. |
