Financial engineering and optimisation provide both power companies and consumers with better decision support in deregulated energy sectors. UCL research has delivered the following benefits to decision makers: (i) a clearer understanding of the role of statistical analysis in imputing missing data on wind speeds and (ii) reduction in energy costs by optimised scheduling of energy technologies. Other benefits have been (i) investment in follow-up research projects by industrial companies and (ii) knowledge transfer via workshops.
The Power Systems research team at Imperial made pivotal contributions in the design of power transmission networks, the equipment within these networks, and non-conventional electricity systems. Since 2008, the impact of their research has been to:
I1) influence government policies by contributing to House of Common Select Committee (2010);
I2) support the Fundamental Review of Supply Quality and Security Standards;
I3) assist National Grid in defining new investment affecting £3bn worth of network assets now approved by the regulator (2013);
I4) provide tools to develop the first offshore networks design standards in 2008, saving an estimated £500m by 2013 to date and a projected overall saving of £1-2bn by 2020;
I5) advance Alstom's design concept for next generation HVDC converter stations for offshore wind connection from TRL 1 in 2009 to TRL 4 in 2013 supported by 3 new patents;
I6) enable UK Power Network to plan network investment of £1.18bn and make savings of £130m (2013) through applying new technologies and demand response;
I7) facilitate a scheme for off-grid energy kiosks for electrification in rural Africa yielding social gains and a business opportunity.
The University of Southampton's pioneering research into energy harvesting has produced proven economic impacts together with impacts on public policy and international standards. Perpetuum, a spin-out from Southampton employing 10 people locally, has attracted £9.6 million in venture capital and developed the world's leading vibration energy harvester. Perpetuum's harvesters are enabling the deployment of zero maintenance, battery-free wireless systems in the rail industry where the technology has revolutionised bearing monitoring. This has enabled, for the first time, real-time monitoring of rolling stock, leading to cost savings, improved reliability, efficiency and safety. Their systems have been deployed on 200 trains across the UK (Southeastern) and Sweden (SJ AB). Southampton's research has driven wider industrial uptake of the technology and Perpetuum's is also the only energy harvester approved for use with the worlds leading suppliers of wireless condition monitoring equipment (GE Bentley Nevada, National Instruments and Emerson). Promotion of the technology has led to a £1.25 million TSB competition on energy harvesting and Southampton researchers are assisting in the development of international standards and increasing public awareness of the technology.
This case study describes the policy impact of research on the deployment of renewable energy in Ireland, the UK and internationally. Three key policy impacts are highlighted;
1) The research has shaped policies underpinning the Republic of Ireland's aim to become a net energy exporter by 2030 and influenced other stakeholders in this field;
2) It has influenced good practice recommended globally by the International Energy Agency on the social acceptance of wind energy;
3) It has generated evidence on the performance of the UK's devolved administrations on renewable energy, which has been deployed in constitutional debates over Scottish Independence.
Dr David Toke's research at the University of Birmingham has contributed to policy made by governments in the UK and EU, and the work and policy of environmentally concerned NGOs. Renewable Energy is a crucial aspect of EU and UK sustainable energy strategies and feed-in tariffs have now become the preferred method of incentivising renewable energy in the UK. Toke made a major contribution to generating this change through his proactive dissemination of research on feed-in tariffs and the publication of a key public policy report, at a time when little was known about this type of policy instrument.
His research has stimulated debate among industry professionals and events organised by him have provided a forum where the industry and NGOs can develop an evidence-based dialogue. Through using popular media to disseminate his research findings, Toke has provided a source for greater public understanding of the related issues, and in particular has challenged the decisions of government. In a broader sense, his research has contributed to improving governmental and financial support for renewable energies in the UK and thus environmental sustainability.
The impact is in the ERPE design of protocols which are subsequently used for evaluation and comparison of the performance of tidal energy converter designs. Researchers within the UK Centre for Marine Energy Research (UKCMER) at ERPE have led much of the fundamental and applied research that has supported the commercialisation of tidal energy technologies through the establishment of new international test standards and protocols.
ERPE researchers have regularly provided evidence which has influenced policy change in marine energy development in the UK and internationally with many ERPE graduating PhD's, subsequently employed in the marine energy sector.
There is a potential conflict between the expansion of marine renewable energy developments, such as offshore wind farms, and seabird conservation. An Environmental Impact Assessment (EIA) must be carried out before planning permission can be granted for such projects. Working with environmental consultancies and key statutory bodies, Professor Furness at the University of Glasgow developed a clear, systematic and widely accepted framework for assessing the impact of wind, wave and tidal projects on seabird populations. This framework has expedited the project development process and lessened potential risks to seabirds, meeting conservation requirements while benefiting all those involved in renewable energy projects by reducing the risk of misjudgements in the impact assessment process.
Research at the University of Strathclyde between 2003 and 2008 directly produced the following impacts from 2008 onwards: 10 wind farms (17 MW aggregate capacity) connected to the Orkney power network from 2009 to 2013 with accompanying economic and environmental benefits; Orkney power network reinforcement deferral saving of £30M from 2009 with repeat deployments of Active Network Management (ANM) technology in other UK power networks; spin-out company formed in September 2008 with total revenues to date of £6.1M, equity investment totalling £3.5M and 35 FTE jobs created; provision of new power system options for long term network plans impacting the 2013 investment decisions in distribution network companies; contribution to the emerging Smart Grid business sector in the UK and overseas from 2008.
Research by staff of the Energy Systems Research Unit (ESRU) at Strathclyde has resulted in advances in the state-of-the-art in dynamic building energy modelling as encapsulated within the Open Source ESP-r program. This new capability enabled practitioners to analyse phenomena and technologies hitherto not capable of being modelled in building simulation tools. The impact stems from the embedding of ESP-r within companies resulting in service improvement and job creation, and applications of ESP-r resulting in energy demand reduction, low carbon energy systems integration and environmental impact mitigation.
Alliance researchers have demonstrated that it is possible to refurbish existing buildings, which make up over 90% of our stock of over 26m buildings, to achieve a reduction in CO2 emissions of up to 80% (domestic properties) and 50% (non-domestic). The research has underpinned a shift of emphasis by UK government from new to existing buildings and the formulation of incentives to encourage building owners to make energy-saving improvements. In partnership with not-for-profit, public and private stakeholders, it has been used by national and local agencies to highlight the potential of improving the energy performance of traditionally constructed, timber-framed and residential mobile homes and incorporated into practical guidance by the Chartered Institution of Building Services Engineers. It is also the technical foundation for an educational software package developed with 100 school children and teachers and praised as exemplary by Education Scotland.
