簡介

輸電事業中,為解決混雜問題的管理工作成為最重要的事情之一。比利時及荷蘭、英國正企圖透過電力輸送的同步化達到解決輸電線混雜問題的目的。

專門於多樣市場領域之調查分析的英國市調公司 Datamonitor Corporation(總公司:London),針對歐洲輸電網發展動向進行相關調查分析及預測,並出版報告書 "The Status of Power TSO Development in Europe" 。

本報告書內容包括:歐洲輸電網市場概要及EU相關法律規範及政策動向、主要歐洲市場的發展趨勢、收益性等分析。內容綱要摘記如下:

Datamonitor的觀點

分析

  • 輸電系統仍舊是各國各自管理,但地區或合作機制更加被強化
    • 消除輸電網混雜問題是輸電業者面臨的最重要的案件之一
    • 利用格網相互連接系統加強混雜問題的管理
    • 輸電業者間合作關係雖有所加強,但仍舊是個別的事業
    • 在北歐地區達成了高水準的送電網整合
  • 垂直整合的公共事業將不從事拍賣輸電網資產的活動
    • 因為輸電事業的子公司創造高收益成果,垂直整合的公共事業業者對賣掉子公司之事面有難色
    • 所有權分割對德國及奧地利的垂直整合公共事業業者應該會產生很大的影響
    • 美國的獨立輸電業者購併了地區的輸電業者
    • 地區的輸電業者模式與市場整體的自由化一致
  • 雖然有EU的規範,但輸電事業的獨立問題仍未解決
    • EU的能源政策刺激開放格網的競爭
    • EU規範如同過去一般刺激電力網的競爭
    • 結構性輸電網的分離是格網改革的重要部分
    • 所有權的完全分割在歐洲已是很普遍的事
  • 輸電系統是歐洲電力市場自由化的關鍵
    • 輸電業者的電力供應與接受關係
    • 歐洲輸電網的所有權及格網管理因國而異
    • 附屬於垂直整合的公共事業的輸電業者在組織化的電力批發市場中沒有角色
    • 規範當局採用的為了限制輸電業者關税的模式幾乎完全不同

Abstract

Overview

Introduction

Power transmission networks are the vital link in the electricity value chain, transporting power from generation suppliers to distibution for end users. By analysing the TSO operating environment it is possible to understand how they will fare in the face of ever increasing liberalisation.

Scope

  • An overview of the European TSO landscape, and the pivotal role the electricity transmission system plays in promoting competition within the sector.
  • An understanding of the development of EU legislation and policies regarding transmission system operators.
  • An in-depth analysis of the different stages of TSO independence development in key European markets.
  • A comparison of the profitability of independent TSOs and those embedded in vertically-integrated utilities.

Report Highlights

Eleven of the twenty markets assessed have gone beyond the legal separation requirement of the Second EU Electricity Directive, with full ownership separation of power networks.

The relatively high profitablity of TSOs belonging to vertically integrated utilities is a strong disincentive to divest by vertically integrated utilities.

Congestion management is one of the most important operational issues facing TSOs. It is forcing TSOs to become increasingly inter-linked, using a variety of mechanisms. For example, Belgium, the Netherlands and the UK use market coupling to syncronise their power imports and exports to manage transmission congestion.

Reasons to Purchase

  • Discern the consequences of network unbundling on vertically integrated utilities.
  • Understand the potential conflicts of introducing a regional transmission organisation in Europe.
  • Understand how national TSOs mitigate cross-border congestion by employing market based methods such as market coupling.

Table of Contents

  • DATAMONITOR VIEW
    • CATALYST
    • EU energy liberalization and increasing inter-regional power trade are the major challenges facing transmission system operators
    • SUMMARY
  • ANALYSIS
    • Multi-regional cooperation will increase, yet transmission systems will retain their national identity
      • Congestion management is the single most important operational issue facing TSOs
      • Grid interconnection systems are used to enhance congestion management
      • Inter-TSO linkages will increase, but will maintain their separate identities
      • The Nordic region has achieved a high level of network harmonization
    • Vertically integrated utilities have no incentive to divest their network assets
      • The relative high profitability of TSO subsidiaries will be a strong disincentive to divest by the vertically integrated utilities
      • Ownership unbundling would have the highest impact on German and Austrian vertically integrated utilities
      • In the US, independent TSOs have merged into Regional Transmission Organizations
      • The RTO model is inconsistent with the goal of full market liberalization
    • Despite EU legislation, TSO independence is unresolved
      • EU energy policies seek to open grid networks to competition
      • EU legislation has consistently focused on stimulating electricity network competition
      • Structural network unbundling is the major catalyst for grid network reform
      • Full ownership unbundling is already common across Europe
    • Electricity transmission systems are key in achieving overall European power market liberalization
      • The Transmission system operator is the link between power supply and demand
      • Ownership and control of grid networks vary across Europe
      • Ownership and control of grid networks vary across Europe
      • TSOs belonging to vertically integrated utilities play little or no role in organized wholesale power markets
      • The models employed to regulate TSO tariffs by regulators are hardly uniform
