Users of renewable energy systems and mini-grid, users involved in rural electrification, manufacturers and suppliers of renewable energy systems and energy storage technology, energy consultants, public utilities, users from developing countries, development programme specialists, energy policy makers, other attendees.

The chairmen tandem is happy to invite you to the 6^th European Conference on PV-Hybrid Systems and Mini-grids in Chambéry close to the French Alps.

This type of systems has been developed to find solutions for the electrification of rural regions and islands and provide an enhanced electricity service.  

In comparison to village electrification with solar home systems a central PV-Hybrid System reduces the specific electricity cost and enables us to provide a grid equivalent service to the users. This cost reduction is achieved by the aggregation of the expensive system components - the photovoltaic generator, the batteries, and the power converters - which are mutualised. 

It is this grid equivalent service which is a crucial condition for starting up economic activities in rural regions, which improve wealth and reduce emigration. This is why PV hybrid systems and Mini-grids are an important tool to achieve the millennium development goals. 

However, hybrid systems and minigrids are more complex, and there are many exciting topics to be addressed in this conference to find cost efficient solutions for reliable systems:

• The higher investments for these systems need more efforts to be done on financial engineering. The political framework conditions are crucial: are the available subsidies for rural electrification designated to grid exten­sion only, or are hybrid systems sufficiently accepted? 
• We need sustainable business models which cope with the high upfront investments, the need of a regular collection of fees from the user, which assure the regular on-site maintenance, and which are able to accumulate funds for the replacement of the battery. 
• We need system components which are cheap, robust, reliable, and which should be easily maintained by a local technician on site. Local manufacture would be great.
• We need hybrid systems that work and use any kind of locally available energy sources. What are the novel examples for hybrid systems and minigrids?
• Even the best system components will not work when they do not work together as a system. The key words are here Energy Management and grid control for the long term and short term system control. These are also ­issues concerning the smartgrids although the stand alone hybrid systems started long before the word smart grid has been invented. The smart grid people surely can learn a lot from PV hybrid systems and minigrids, what can we learn from them?
• The user interaction with the system is crucial for its functioning, and there is no success without user satisfaction. How does the user use the system? How does he learn the limits and possibilities of the system?
• Finally, we need news on the lessons learned from field experience 

The conference location of Chambéry has not been only chosen for its beautiful settings. Just a jump away, there is the solar innovation campus housing INES, the National Institute of Solar Energy, which will be happy to receive you for a technical visit! 

We are looking forward to welcoming you in Chambéry!

Energy Management Workshop

Centre de Congrès Le Manège, Chambéry, France

April 25th, 2012

Energy Management is crucial for the operation of PV-Hybrid Systems. We can distinguish two levels: on the production side, it mainly assures the proper operation of the systems’ battery with the aim to assure electricity service and to maximize battery lifetime. On the other hand, tools are needed to maximize the matching of the electricity demand to the solar generation and to adapt this demand to the system state.
This one day workshop gives for these two aspects an introduction on the state of the art, up-to-date developments and a practical review on the topic. With a final session on the industrial realizations, the participant will be able to implement Energy Management in the field.
Each talk includes 5 minutes discussion.

New Task on PV Hybrids and Mini-Grids

Chambéry, France - April 25th, 2012

(in advance of the 6th European PV Hybrid and Mini-grid Conference)
The current IEA Photovoltaic Power Systems Programme (PVPS) Task 11 on PV hybrid systems in mini-grids completes its work plan in 2011.  Experts from PVPS member countries who are interested in continuing the work of Task 11 in a new PVPS sponsored Task are invited to a planning meeting from 17.00 hrs to 20.00 hrs on 25 April, 2012 in the Centre de Congrès Le Manège, Chambéry, France  (venue of the 6th European PV Hybrid and Mini-Grid Conference).

The purposes of this initial meeting are to

• Gauge the level of interest in a new PVPS R&D project (Task) on PV hybrid systems and mini-grids.
• Identify potential topics for the Task.
• Set up a working group to prepare a draft Task Work Plan for discussion at the IEA PVPS Executive Committee meeting in the Fall of 2012 (assuming there is sufficient interest among Experts).

Interested Experts are requested to contact the Task 11 Operating Agent, Konrad Mauch (konrad.mauch@ieee.org) to obtain further information.  General information about the IEA PVPS and Task 11 can be found at www.iea-pvps.org and www.iea-pvps-task11.org .

Chambery is close to the French Alps near Lac du Bourget. Once capital of Savoie, the ancient town is famous for its Chateau and its 15th century Cathedral. 

Chambery can be reached via Lyon Airport (75 km) and Genève Airport (90 km). The TGV operates daily from Paris (3h) and Lyon (1h).
