R&D Drivers and Obstacles to Innovation in the Energy Industry

The energy industry is facing substantial challenges that require innovation to be fostered. Nevertheless, levels of R&D investment and innovation remain quite low in comparison with other sectors. In this paper we analyse the main drivers of R&D investment and obstacles to innovation in the energy industry. We examine, firstly, whether the stated R&D objectives pursued by firms play a role in their R&D effort. Secondly, we analyse the effects of financial, knowledge and market barriers on the innovation outcomes of the firms. We rely on data from the Technological Innovation Panel (PITEC) for Spanish firms for the period 2003-2010. We use a structural model with three equations corresponding to the decision to carry out R&D or not, the R&D effort and the production of innovations. The results of the econometric estimations show, first, that R&D intensity is positively related to process innovation. Second, the main barriers that hamper innovation in the energy industry are related to market factors while financial and knowledge obstacles are not significant.

The Economic Impact of Electricity Losses

Although electricity losses constitute an important, but inevitable, amount of wasted resources (and a share that has to be funded), they remain one of the lesser known parts of an electricity system, and this despite the fact that the decisions of generators, transmission and distribution system operators and consumers all impact on them. In this paper we analyse the effects of such losses from two perspectives: from that of consumption or outflows and from that of generation or inflows. Given that end-user consumption varies across the day, consumption has direct implications for electricity losses. Indeed, demand-side management policies seek to encourage consumers to use less energy during peak hours and to reduce network congestion. At the same time, from the perspective of generation, the recent growth in distributed generation has modified the traditional, unidirectional, downward flows in electricity systems. This affects losses as energy is produced in the lower voltage network, which is closer to points of consumption. In this paper we evaluate the impact of consumption patterns and different generation technologies on energy losses. To do so, we draw on data from a real electricity system with a high level of renewable penetration, namely, that of Spain between 2011 and 2013. To the best of our knowledge, this is the first paper to analyse the real impact of consumption and the effect of each generation technology on energy losses, offering an opportunity to evaluate the potential benefits of demand-side management policies and distributed generation. Based on our results, we make a number of regulatory recommendations aimed at exploiting to the full these potential benefits. Our results should serve as a baseline for countries that are in the early stages of implementing these policies.

Are Energy Market Integrations a Green Light for FDI

This paper studies the effect of energy market integration (EMI) on foreign direct investment (FDI). EMIs diminish energy uncertainty and price volatility in the host country and affect FDI through two channels: first, by harmonizing energy prices and, second, by reducing price dispersion. FDI may, as a result, increase both within and outside the EMI area, through energy stability mechanisms and price mechanisms, respectively. An empirical application on a global dataset including bilateral FDI data, during 2003-2012, using the gravity equation, shows that the integration of Portugal and Spains electricity market in 2007 increased the amount of FDIs participants. Additionally, a positive increase in FDI from neighboring countries (in this instance, France), albeit lower in magnitude, is observed.

Electricity Regulation and Economic Growth

The main objective of this paper is to analyse the effect of electricity regulation on economic growth. Although the relationship between electricity consumption and economic growth has been extensively analysed in the empirical literature, this framework has not been used to estimate the effect of electricity regulation on economic growth. Understanding this effect is essential for the assessment of regulatory policy. Specifically, we assess the effects of two major regulations, renewable energy promotion costs and network cost, on electricity consumption and growth. A dataset for the period 2007-2013 and 22 European countries was compiled based on CEER reports and EUROSTAT databases. The results of the empirical analysis show that the two regulation instruments have a negative effect on electricity consumption and economic growth and provide estimates of their effects on growth in quantitative terms.

Why do manufacturing industries invest in energy R&D?

Energy R&D can have major social and economic impacts and is a critical factor in addressing the challenges presented by climate change mitigation policies. As well as the energy utilities themselves, firms in other sectors also invest in energy R&D; however, while various studies have examined the determinants of R&D in the former, there are no analyses of energy R&D drivers in other industries. This paper seeks to fill this gap by examining the determinants of investment in energy R&D in non-energy industries. We focus on manufacturing industries where we can differentiate between energy and non-energy R&D related expenditure. The empirical analysis is carried out for 21 sectors in Spain for the period 2008–2013. To overcome problems of data availability, we construct a comprehensive database from several surveys. The data show the importance of taking into account the efforts devoted to energy R&D by the manufacturing sectors in order to have more complete information about the total investment made in energy R&D. The results of the estimations indicate the importance of the energy R&D developed by firms that supply the energy utilities.

What are the Determinants of Investment in Environmental R&D?

To face the challenges posed by climate change, environmental R&D and innovation are critical factors if we hope to cut emissions; yet, investment in environmental R&D remains below the social optimum. The aim of this paper is to analyse the determinants of investment in environmental innovation and to detect the differences, if any, with the determinants of investment in general innovation. R&D investment is one of the key variables for analysing the resources devoted to innovation; however, data constraints hamper the use of this variable when examining the drivers of eco-innovation. The literature reports that demand factors in general and collaboration with stakeholders play a crucial role in generating such investment. In addition, this paper similarly examines the relationship between environmental innovation R&D expenditure and a range of policy instruments, including environmental regulation and other policy measures including R&D subsidies and environmental taxes. The empirical analysis is carried out for 22 manufacturing sectors in Spain for the period 2008–2013. To overcome problems of data availability, we construct a comprehensive database from different surveys.

Innovation strategies of energy firms

Investment by energy firms in innovation can have substantial economic and environmental impacts and benefits. Internal R&D is the main input and driver of the innovation process, but innovation involves other activities, including capital purchases and other current expenditures. While the R&D activities of energy firms have been analysed, few studies have examined the typology of their innovation activities. Here, we analyse the impact of the main characteristics of the sector’s firms on their decisions to invest in each of three types of innovation activity: namely internal R&D; external R&D; and, the acquisition of advanced machinery, equipment or software. In conducting this analysis, we take the potential persistence of innovation activities into account. We also examine the role that different innovation objectives have on firms’ investment decisions. Given that engagement in a specific type of innovation may result from decisions that are not taken independently of each other, we analyse whether there is any complementarity between the three innovation activities. In carrying out the empirical analysis, we draw on data for private energy firms included in the Technological Innovation Panel (PITEC) for Spanish firms for the period 2004-2013. We use panel triprobit models to examine potential complementarity.

Unexpected consequences of liberalisation: metering, losses, load profiles and cost settlement in Spain’s electricity system

European energy markets have undergone a major transformation as they have advanced towards market liberalisation and it is vital that the details of these developments be carefully examined. The success of liberalisation is based on smart regulation, which has been capable of providing solutions to unforeseen events in the process. Our paper seeks to contribute to existing understanding of the unexpected consequences of the liberalisation process in the power system by examining a natural experiment that occurred in Spain in 2009. In that year, the electricity supply by distribution system operators (DSOs) disappeared. This positive change in retail market competition, as we demonstrate in this paper, has had an unexpected effect in terms of the system’s balancing requirements. We undertake a rigorous assessment of the economic consequences of this policy change for the whole system, in terms of its impact on final electricity prices.
