Need motivation to save energy? - Go for social media competition!

There is a large potential by closely monitoring the energy consumption of your appliances in a comprehensive overview. Being aware of the largest energy consumers and the general energy demand over the day, one can optimize his/her household to reduce power consumption or to shift consumption to a daytime where the demand/supply situation is better.
However, what is the motivation to do so?
As it can be seen in other situations (like riding a bike vs. taking the car, etc.), saving a few bucks might not be enough motivation to effectively change the consumers' behavior.
Austin Montgomery, University of Waterloo gives a possible solution to this problem in his video "Making the Smart Grid Smarter with Social Media": make it a competition on social networks!

By the way, this is my favorite video from the IEEE SmartGridComm 2011 video contest. Check for the other nominated clips.

Siemens smart grid innovation contest winning ideas

In April 2011, Siemens called for an idea contest on Smart Grid Innovation. Now, the four best ideas out of 464 submitted contributions have been announced in an award ceremony in Berlin on September 15th. The winning ideas in short:
Christian Huder from EIT ICT Labs, (Germany) won one of the four prices with his idea
"Smart Grids - comparison or regulatory approaches and their implications on business models" discussing the roles of state, market, and providers.
Slobodan Matic from University of California, Berkeley, (USA) elaborated successfully on the concept of an "Integrated Modular Architecture for Distribution Automation".
If you want acceptance, you need games. Vasilis Nikolopoulos from Intelen, (Greece) explored this topic under the idea of "Advanced Demand Response Behavioral Gamification". Consumers having used to social media and gaming will be happy to play a game of consumption optimization in the future grid.
Multi-agent systems are a promising model for smart grids. Logenthiran Thillainathan from the National University of Singapore introduces the concept as an architectural paradigm for autonomously operating smart grids.

Congratulations to the winners and looking forward to see the ideas soon in action!

Google and Microsoft back away from online power metering

Google PowerMeter and Microsoft Hohm are online web applications that enable consumers to analyze their energy usage and provide energy saving recommendations. The basic idea is to have an  application in the cloud that is using predictions, smart meters, and energy monitoring devices in order to provide you with information and recommendations about your home's power usage.

While Google's application came for free, Microsoft's tool was planned as a product to create revenue. Now, both projects are discontinued. PowerMeter was retired by Google in September 2011, joining the club of Google Wave and Google Health. In Google's official blog, the reason is only briefly stated as "efforts have not scaled as quickly as we would like", which leaves room to some interpretation. Microsoft's Hohm will be discontinued on May 31, 2012 due to a lack of consumer uptake.

This is sad, since a comprehensive user interface with web integration is a major asset in comparison to existing powermeters with their limited LCD displays and gray buttons. Remember, we are talking about an appliance that is basically planned to enter every household, not just being a tool for geeks. We certainly need a convenient user interface here.
With the bailout out of Google and Microsoft, two important drivers of innovation will be missing, on the other hand this might open the market for new developments. Apple, having filed a patent on a smart-home energy management dashboard system seems to be planning something, but it's still unclear what we will get.

IEEE Journal on Selected Areas in Communications: Smart Grid Communications Series

The IEEE Journal on Selected Areas in Communications (JSAC) has inaugurated a new series on communications for Smart Grid. “Smart Grid” refers to the modernization of the electric grid to enable more efficient generation, transmission, distribution, and usage of energy, resulting in sustainable energy production and consumption with reduced adverse effects on the environment and increased power reliability. While advances in renewable energy and network control are needed, advances in communication technologies, data fusion and mining, and scheduling and optimization are also crucial for realizing this vision. It is anticipated that many of the same communications technologies that have revolutionized our way of life in the past few decades will have direct applicability to Smart Grid, for example, the use of wireless communications in a single distribution network to collect and exchange information about quality, consumption, and pricing of electricity. While many off-the-shelf communications technologies can be deployed today in the Smart Grid, their use may lead to numerous inefficiencies, especially if energymanagement-specific features are not included in data compression and the data collection infrastructure. Moreover, allowing multiple distribution networks to operate side-by-side, interface to customer equipment, and share information in a secure and reliable fashion poses a number of difficult communications challenges that remain unanswered in the context of Smart Grid.

This series focuses on identifying the numerous communication challenges posed by the Smart Grid and exploring research avenues for addressing them. Original contributions that are unpublished and not currently under review by any other journal are solicited in relevant areas of Smart Grid communications including but not limited to the following:

• Physical and MAC layer protocols for Smart Grid applications
• Spectrum sharing, coexistence and interference mitigation in Smart Grid communications
• Network control for the power grid
• Smart Grid sensor data fusion and mining models
• Communications to support demand-response, load, and pricing management
• Smart Grid cyber-physical network modeling and performance analysis
• Measurement data from Smart Grid testbeds and field trials
• Architecture and network topology for Smart Grid applications
• Cyber and physical vulnerabilities and Smart Grid security

Prospective authors should prepare their submissions in accordance with the rules specified in the ‘Information for Authors’ section of the JSAC guidelines ( Each submission will be reviewed by at least three experts and evaluated by an editorial board dedicated to the area of communications for Smart Grid. All manuscripts should be submitted in PDF format via email to Dr. Nada Golmie, While manuscripts can be submitted at any time, they should be submitted according to the following timetable to be considered for the inaugural July 2012 issue:

Manuscript submission: September 15, 2011

The smart grid challenge

The transformation of our energy system from fossil fuel resources to sustainable resources is one of the great challenges of our time, but opens also a great chance for establishing a more efficient and robust distribution of energy to the benefit of all its users. A way to do this is the intelligent integration of the behavior of all users (generators and consumers) of an electricity grid to optimize the operation of the system, e.g., by balancing energy consumption based on availability and demand.

In order to achieve this goal, we need to define innovative products and services together with intelligent monitoring, control, communication, and self-healing technologies: Electrical devices, generators, and energy storages will be integrated with local intelligence and a network interface. These smart meters will form a network that dynamically adapts pricing and distribution based on demand, supply, and network load. The emerging network will be a self-organizing smart grid which efficiently maintains existing services, allows for prediction of future energy and network requirements.

However, the challenge is not a mere technical one. A main characteristic of the smart grid is that it will allow consumers and suppliers to play an active role in optimizing the system. While this is a very positive aspect, it leads to new challenges such as social aspects like fairness and acceptance, economic aspects such as market stability and resilience against speculation attacks, and legal issues such as warranty, data security and privacy. Last but not least, the smart grid forms a complex system of interacting agents, which will require new models similar to those from physics, biology or economics.

The goals of the smart grid are ambitious. But considering the importance of energy to our society, there is no other chance than to work on it in a global cooperative effort. There is no time to wait.
