Maintaining equilibrium in the European power grid

Ansaldo

The liberalization of energy markets in Europe and the separation of generation, transmission and distribution in most countries have played a vital role in increasing the efficiency of energy systems for the benefit of industrial users and consumers alike.

New players have strengthened their presence in the energy markets, endowed with higher efficiency, a greater propensity for investment, and greater generation capacity compared with former monopoly players.
At the same time, a significant improvement has been achieved in the transparency of decision-making processes at a regional and pan-European level regarding development of an interconnected European grid. This has been enabled by the publication of the Ten-Year Network Development Plan of the European Network of Transmission System Operators for Electricity (ENTSO-E) as part of the framework set out by the EU's Third Energy Package.

Processes to harmonize Europe-wide requirements in light of current and future system developments have also been discussed regularly among network operators, stakeholders and regulators. In 2013, ENTSO-E released its latest Network Code on 'Requirements for Generators' (NC RfG) and published NC RfG Implementation Guidelines to support the code by highlighting the impact on specific technologies, the link with local network characteristics, and the need for co-ordination between network operators and grid users.

Good progress has undoubtedly been made in respect of both market liberalization and EU policy; however, the economic and financial crisis of 2008-2009 hit at a time when energy systems were just starting out on their transformation journey. Unfortunately, it caught most utilities unprepared. Following a period of significant capital expenditure and increased mergers and acquisitions activity, most found themselves loaded with debt. This is why European utilities have been ranked among the worst-performing sectors in the global share indices over the last five years.
