3There is an ongoing transition towards renewable energy sources in order to combat climate change. National power grids are suffering due to the rapid introduction of new energy sources and have other disadvantages. Local Energy Systems (LESs) are a beneficial example of an off-grid energy systems that can aid the energy transition. LESs are community driven and require participating and steering members. This can be achieved through empowering end-users to become active participants or steerers. End-users can be empowered to become an active participant through engagement with energy management activities. This does not work for empowering to steer, which begs the question, how to empower end-users or participants to become steerers in Local Energy Systems. Through a literature review this study explores the importance of establishing a group containing steerers with diverse skills, strong leadership, and engagement with the environment and community. Additionally, this study identifies the strategy that empowers end-users to steer. Which is training technological and managemental skills; and training capabilities in establishing relations with local participants and intermediary organisations. To apply these findings more precisely a secondary analysis is conducted on a survey with 599 participants. The original study researched willingness to participate in LESs, however the secondary analysis establishes three important factors to predict willingness to steer. These are energy independence, community trust, and community resistance. Additionally, men with a high level of education are most willing to become steerers per default, thus different demographics generally require more empowerment.

The transition to a decentralized renewable energy system requires the transformation of communities. Increasingly, citizens become ‘prosumers’ and take energy production in their own hands.

Rapid convergence of utility and mobility solutions enabled by data and the Internet of Things is future-proofing economies around the world, delivering liveability, sustainability and resilience, and importantly decreasing pressure on utility bills and infrastructure costs. Australians cannot miss out on the many benefits brought to families and businesses by the digitisation of infrastructure and services, not just reduced household bills but also the ability to generate income as prosumers, not consumers. Localised sustainable Next-Gen infrastructure and services are growing from within communities, creating a new class of consumer-the prosumer: where customers are more than consumers but also producers. Prosumers have the ability to generate free energy from the sun at home or office and sell the excess, recycle water and waste reaping the financial benefit, avoid the second largest household expense of a car by sharing mobility, and access shared data networks to plug in and play at little cost. Planning frameworks play a critical role in enabling a new utility prosumer future in Australia and reform of planning gateway processes is essential. This article highlights Sydney’s Central Park as a best practice urban infill development showcasing how the flows of water and energy are organised to provide enhanced sustainability, liveability and resilience for the local and neighbouring communities. Central Park proves the benefits of taking a precinct approach to utility and mobility services. It shows how these benefits can grow and be exported to neighbouring buildings and existing communities, in this case University of Technology driving inclusion and affordability. Central Park also demonstrates the opportunities to drive deeper socio/environmental benefits by enabling prosumer services through low-cost access to utility services and circular resource flows. Importantly, this article demonstrates that Central Park’s phenomenal sustainability benefits can be replicated at scale in land release communities, but planning reform is required.

What’s online video today, fifteen years into its exponential growth? In the age of the smart phone, video accompanies, informs, moves, and distracts us. What started off with amateur prosumers on YouTube has spread to virtually all communication apps: say it with moving images. Are you addicted yet? Look into that tiny camera, talk and move the phone, show us around, and prove the others out there that you exist!
With this third reader the Video Vortex community — initiated in 2007 by the Institute
of Network Cultures — proves that it is still alive and kicking. No matter its changes, the network is still driven by its original mission to develop a critical vocabulary for this rapidly spreading visual culture: what are the specific characteristics of online video in terms of aesthetics and political economy of image production and distribution, and how do they compare to film and television? Who is the Andre Bazin of the YouTube age? Honestly, why can’t we name a single online video critic? Can we face the fact that hardly anyone is using the internet? What are you going to do with that 4K camera in your smartphone? Have we updated Marshall McLuhan’s hot and cold media for our digital era yet? Who dares? We see the Woman with a Smartphone Camera in action, but who will be our Vertov and lead the avant-garde? Who stops us? Let us radically confront the technological presence as it is and forget the pathetic regression to past formats: radical acceptance of the beautiful mess called the net.

Peer-to-peer (P2P) energy trading has been recognized as an important technology to increase the local self-consumption of photovoltaics in the local energy system. Different auction mechanisms and bidding strategies haven been investigated in previous studies. However, there has been no comparatively analysis on how different market structures influence the local energy system’s overall performance. This paper presents and compares two market structures, namely a centralized market and a decentralized market. Two pricing mechanisms in the centralized market and two bidding strategies in the decentralized market are developed. The results show that the centralized market leads to higher overall system self-consumption and profits. In the decentralized market, some electricity is directly sold to the grid due to unmatchable bids and asks. Bidding strategies based on the learning algorithm can achieve better performance compared to the random method.

Recent years have shown the emergence of numerous local energy initiatives (prosumer communities) in the Netherlands. Many of them have set the goal to establish a local and sustainable energy provision on a not-for-profit basis. In this study we carried out exploratory case studies on a number of Dutch prosumer communities. The objective is to analyse their development process, to examine the barriers they encounter while organising their initiative, and to find how ICT could be applied to counteract these barriers and support communities in reaching their goals. The study shows that prosumer communities develop along a stepwise, evolutionary growth path, while they
are struggling with organising their initiative, because the right expertise is lacking on various issues (such as energy technology, finance and legislation). Participants stated that, depending on the development phase of their initiative, there is a strong need for information and specific expertise.
With a foreseeable growing technical complexity they indicated that they wanted to be relieved with the right tools and services at the right moment.
Based on these findings we developed a generic solution through the concept of a prosumer community shopping mall. The concept provides an integrated and scalable ICT environment, offering a wide spectrum of energy services that supports prosumer communities in every phase of their evolutionary growth path. As such the mall operates as a broker and clearing house between 2
prosumer communities and service providers, where the service offerings grow and fit with the needs and demands of the communities along their growth path. The shopping mall operates for many prosumer communities, thus providing economies of scale. Each prosumer community is presented its own virtual mall, with specific content and a personalised look-and-feel.

The traditional energy industry is transitioning from a centralised fossil fuel based industry to a decentralised renewable energy industry for several reasons including climate change, policy, and changing customer needs. Furthermore, renewable sources, such as wind and solar, are intermittent and unpredictable. This has implications for the business models of energy producers, such as increased mismatch between demand and supply, increased price volatility, shift in drivers of value creation. Due to the low marginal cost of production and the intermittent nature of renewables, the price volatility on the electricity markets, in particular the imbalance market, are expected to increase. However, there is potential for market parties operating in the electricity sector to profit from this development by providing flexibility to balance electricity supply and demand. Therefore, new business models are needed that can harness and exploit flexibility in a viable manner. In these business models, flexibility becomes the key driver of value creation.

This paper describes innovation in existing and future Master’s degree education in renewable energy at the Hanze University of Applied Sciences Groningen (Hanze UAS). Interrelationships between research and industry are significant within this education. Clearly illustrated by development of the Energy Transition Centre (EnTranCe), this facility at Hanze UAS uses open innovation to accelerate the application and functionality of technology. Enabling consumers to become producers (prosumers) is central to the approach to energy transition in Groningen. The city is located next to the largest natural gas field in Europe. As the fuel most suited to balancing the intermittent character of renewable energy sources, it is central to the technical approach at Hanze UAS. With the coming of the Energy Academy Europe and inclusion of Hanze UAS within the European Renewable Energy Research Centres Agency, Groningen is an international partner in education and perfectly positioned to innovatively assist energy transition.

In deze presentatie gaat Arjen van Klink in op de rol van strategie in het mkb. Strategisch management is traditioneel iets voor het grootbedrijf, kleinere bedrijven ontbreekt het vaak aan middelen om een strategie te beschrijven en te implementeren. Traditionele strategische concepten kritiek: het gaat vooral om papier, het zijn eenmalige acties en het zijn top-down plannen. Deze aanpak voldoet niet meer in de turbulentie van vandaag. Dat geldt voor alle ondernemingen, óók voor mkb-ondernemers. Vooruit kijken is weliswaar erg moeilijk, maar opereren zonder strategie is tegenwoordig enorm risicovol: als traditionele strategie-instrumenten niet werken, hoe dan wel? De stelling van de presentatie was dat mkb's niet zozeer kunnen leren van 'corporates' en hun strategietools, maar van succesvolle start-ups: zij werken aan doorlopend aan hun strategie via iteratieve stappen met veel contact met klanten en met experimenten.

The need for increasing further the penetration of Renewable Energy Sources (RESs) is demanding a change in the way distribution grids are managed. In particular, the RESs intermittent and stochastic nature is finding in Battery Energy
Storage (BES) systems its most immediate countermeasure. This work presents a reality-based assessment and comparison of the impact of three different BES technologies on distribution grids with high RES penetration, namely Li-ion, Zn-Air and Redox Flow. To this end, a benchmark distribution grid with real prosumers’ generation and load profiles is considered, with the RES penetration purposely scaled up in such a way as to violate the grid operational limits. Then, further to the BES(s) placement on the most affected grid location(s), the impact of the three BES types is assessed considering two Use Cases: 1) Voltage & Congestion Management and 2) Peak Shaving & Energy shifting. Assessment is conducted by evaluating a set of technical Key Performance Indicators (KPIs), together with a simplified economic analysis.
