When governments open up opportunities for private investment in traditional public sector areas, it is increasingly clear that a useful range of performance management information needs to be available to both government and business. Government needs to know how it is performing, comparatively, within and beyond its own domain, for the development of public policy and productivity enhancement. Business needs to know, understand and monitor the industry environment in which investment is contemplated or has already taken place. Performance measurement and monitoring is especially important where governments wish to attract foreign direct investment (FDI) to their shores. Whether governments manage performance and information well or are still constrained by bureaucratic and political thinking is still at issue. Using the example of the contrived national electricity market in Australia, this article, through literature and document review, examines the likely value to government and business of performance information, now available in the public domain. First, the article considers some of the changes to the Australian electricity industry. Second, specific performance indicators relevant to the national electricity market are examined in terms of their utility for government and business decision-making. Third, the impact of the political environment on performance management information is explored. The article concludes that while some important quantitative performance management information is available in a rational sense, other more political, qualitative indicators also need to be taken into account.

The European Union considers that offshore wind power will play a key role in making the EU the first climate-neutral continent by 2050. Currently, the potential of offshore wind energy is still untapped in Spain. Furthermore, the characteristics of the coastline in Spain require floating technology, making it challenging to install wind farms due to their current high cost. This work seeks to quantify the impact that Spanish offshore wind energy would have on the Iberian electricity market. Several offshore wind scenarios are evaluated by combining available information in relation to areas suitable for installing wind farms and wind resource data. The impact on the day-ahead electricity market has been obtained by reproducing the market, including these new offshore wind generation scenarios. The introduction of this renewable energy results in a market cost reduction in what is known as the merit-order effect. According to our estimates, for each MWh of offshore wind energy introduced in the market, there would be a market cost reduction of 45 €. These savings can serve as a reference for regulators to adjust their policy framework to boost floating wind offshore generation.
