Leveraging Our Expertise To Inform International RE Roadmaps

Analysis Insights: April 2015

Mexico is expanding renewable energy as a key strategy to reduce greenhouse gas emissions from its electricity sector. One of the key challenges to meeting the renewable goal—35% renewable energy by 2024—is integrating variable wind and solar resources into the existing grid.

Through the U.S. government's Enhancing Capacity for Low Emission Development Strategies (EC-LEDS) program, NREL is collaborating with Mexico's ministry of energy, power system operators, research institutions, and policymakers to set and meet technically achievable annual renewable energy targets to support Mexico's renewable energy goal. NREL and its Mexico partners developed the Renewable Electricity Grid Integration Road Map for Mexico, which outlines technical priorities and recommendations for the integration of renewable energy technologies at large scale, and the steps energy institutions need to take to determine how the electricity infrastructure and systems must change to accommodate high levels of renewables.

The roadmap focuses on analysis methodologies—including grid expansion modeling, resource characterization, forecasting, and grid operational practices—to evaluate the infrastructure and operational impacts of increasing levels of renewables. The roadmap gives policymakers a basis for assessing potential challenges, solutions, and economic impacts of increasing the level of variable RE penetration on the grid and gives system operators confidence that reliability concerns can be met.
