2 1 What does ReGrid mean? Awarded certificates (Certified ReGrid Manager and Attendance Certficate) Target groups Curriculum Estimated effort for the training, textbook and offline-reading Forum and support by RENAC Virtual Classroom Final Exam Dates Costs and registration... 6 Attachment: Details of curriculum What does ReGrid mean? The material for this online training was developed within the ReGrid programme on "Capacity Building on Integration of Large Amounts of Renewable Energy into the Electricity Grids within the German International Climate Initiative (ICI). The Renewables Academy AG was commissioned by the Ministry for the Environment, Nature Conservation and Nuclear Safety to facilitate the ReGrid program. ReGrid demonstrates how a high amount of renewable energy can be safely integrated into the electricity supply and which steps are essential for implementation. This training is meant for you if you would like to: Learn more about methodologies to plan and operate electricity systems with large amounts of wind and solar power Learn how to manage transformation processes in your energy system and/or your company towards large amounts of wind and solar power Overcome barriers and hurdles to integrate wind and solar into the grid Gain knowledge to lead high level working groups on grid integration strategy development Gain knowledge to prepare and evaluate call for tenders for grid integration of wind and solar Receive a certificate from the Renewables Academy (RENAC) AG in Germany to demonstrate your knowledge Learn from senior experts and be part of a growing international network of experts Page 2 of 10

3 2 Awarded certificates (Certified ReGrid Manager and Attendance Certficate) In an online survey RENAC evaluated the interests of potential participants and found that more than 90% were interested in obtaining a certificate. Therefore RENAC offers two types of certificates: Certified ReGrid Manager: certificate for persons who successfully passed the online exam ( Final Exam). Participants will receive a printed and signed certificate from the Renewables Academy AG (in addition to a PDF-Version per mail). The certificate will include a specific grade. ReGrid Online Attendance: certificate for persons who worked through all the exercises/lectures, but did not attend or did not pass the final exam. Participants will receive a PDF-file by with a signed certificate from the Renewables Academy AG. This certificate will indicate completion of the training, but will not include a specific grade. 3 Target groups The target groups for the seminars are professionals who have the following engineering, technical or management responsibilities: Development and implantation of strategies to integrate large amounts of renewable power into the existing electricity grid Design and operation of electricity systems, grid planning, Development of grid codes and grid connection studies for renewables Professionals working in the following institutions / companies: Ministries and administrations Electricity Utilities and independent power producers Transmission grid operators and distribution grid operators Energy service companies/utilities of the energy sector Companies/ organisations developing, implementing, running or financing renewable energy projects Financing institutions, law firms and non-governmental organizations (NGOs) interested in the topics of grid integration of renewables The course material is suitable for self-study by persons who passed a technical university study (bachelor or higher) or who have comprehensive practical experiences in the planning and operation of electricity grids / power systems. It is also suited for master students in this field. Within the Renewables Academy Online, the training Applying Renewable Energy serves as preparation for this training. It can be booked by those who need to build up or refresh their knowledge on photovoltaic, wind, CSP or biogas technologies, and on frequency and voltage regulation in electrical grids. Page 3 of 10

4 4 Curriculum The online training comprises eight courses (for further details of the curriculum see attachment 1): Tools and methods for developing temporal and spatial highly resolved scenarios for electricity generation from wind, PV and CSP Generator concepts for renewable generation Short term prediction of wind and solar power Balancing power Grid codes for renewables Generation expansion planning of systems with high share of wind and PV generation Grid integration studies and system integration studies Storage 5 Estimated effort for the training, textbook and offline-reading You will need at least 5 hours per week to work through the material (reading, watching online lectures, self-evaluation and preparation for final exam). RENAC will upload a new course every two weeks. No textbooks are required for this training. RENAC will recommend additional publications that you may find helpful, but any material you need is included as part of the training. If you would like to read the course material offline, you can generate a personalized PDF document of the course materials for personal use (distribution prohibited). 6 Forum and support by RENAC The e-learning platform contains a forum. Participants are welcome to use the forum to raise questions or start discussions. The forum shall be an important social element of the classroom where the priority is a friendly, open atmosphere that allows participants to ask questions freely. The forum is the appropriate venue where participants can: Ask questions about the training, ask for clarification Share extra information relating to the course Help each other out Contact other participants to form study groups RENAC will support participants to answer/solve upcoming questions during the self-study phase. Therefore RENAC will monitor the forum and will respond to all questions within 48 hours (working days). A technical introduction on how to use the learning platform will be given at the beginning of the training. If a technical problem with the site occurs, participants can send an to backhaus@renac.de. RENAC will try to find a solution as soon as possible. Page 4 of 10

5 7 Virtual Classroom Two live virtual classroom sessions (1 hour each) are included in the online training. The first VC session will be a general introduction to the online platform and to the contents of the training. The second session will deal with specific topics of the training and serve as preparation for the final exam. You need to have Flash player installed to participate in the VC, also a headset or loudspeakers to hear the presenters speak. If there are less than 10 participants in the VC, everyone can contribute via microphone, otherwise all questions and remarks can be made in the live chat during and after the lecturer s presentation. 8 Final Exam After the self-study phase, participants can attend a final exam. The exam lasts 120 minutes and comprises 80 multiple-choice questions. Participants will be responsible for ensuring their internet access with a stable connection during the exam. The exam has one question per page and participants will therefore need to submit their answers one after the other. This way, it is ensured that the system saves all answers, even if the internet fails or is interrupted during the exam. With more than 80% of correct answers participants will pass this exam and obtain the Certificate Certified ReGrid Manager (CRGM). RENAC will correct the exam, but details of the exam or individual results will not be published by RENAC. 9 Dates Early bird deadline: 18 August, 2015 Deadline for registration: 28 September, 2015 Login information sent out: 30 September, 2015 Start of the training: 1 October 2015 Live virtual classroom Introduction to the Online Platform : 7 October, 2015; 11 a.m. CET Upload of a new course every two weeks: October 2015 until January 2016 Live virtual classroom Energy yield of RE : 10 December 2015 Live virtual classroom CRGM-Training Exam : 3 March 2016 Exam: 30 March 2016 Re-exam: scheduled individually if necessary End of online phase: 31 March 2015 Page 5 of 10
