"CEM Days - Integration of Renewables in the Electric Sector: Paths and Challenges to Energy Planning

On 21-23 November 2018, Rio de Janeiro hosted the workshop "CEM Days - Integration of Renewables in the Electric Sector: Paths and Challenges to Energy Planning". The event, organized by EPE, took advantage of the framework enabled by the Clean Energy Ministerial (CEM), and its aim to empower energy decision makers around the world with the up-to-date information and tools, as means to accelerate transition to low carbon energy. The workshop brought together experts and policy makers to discuss strategies to support a secure and cost-effective integration of higher shares of VRE – Variable Renewables Energy, such as wind and PV power. The event was promoted and supported by the International Energy Agency – IEA, of which Brazil is associate since October 2017, and GIZ - Deutsche Gesellschaft für Internationale Zusammenarbeit (German Agency for International Cooperation). The event also had special participation by the Brazilian National System Operator (ONS) and the National Laboratory for Renewable Energy – NREL.

In addition to the above mentioned institutions, we had participants from power generation and distribution utilities, industry associations, consulting companies, universities, banks, among others. 

It was possible to identify many challenges to adapt the energy planning methodologies and tools, related to emerging technologies that redefine the profile of power generation and the use of transmission and distribution assets, as well as business models, market and regulatory framework, consumer behavior and electricity demand profile, all that transforming the industry, the energy mix and its associated infrastructure. 

By organizing this event, EPE strengthens its engagement in high-level technical discussions regarding challenges for the integration of VREs in the power system and consolidates important partnerships with national and international institutions aiming to exchange valuable experiences for energy planning.
