SENER Single Window Cuts Electricity Self-Consumption Permit Times by 60%

Mexico's Ministry of Energy (SENER) has launched the Single Self-Consumption Window (VUA), a digital platform that consolidates nine permitting procedures for on-site power generation at facilities ranging from 0.7 to 20 megawatts (MW), setting binding maximum deadlines that cut resolution times by up to 60 percent compared to the previous framework.

The VUA, published in May 2026, is the procedural mechanism that completes the administrative simplification mandated by the Electricity Sector Law. The new module operates within the Energy Window and unifies procedures that previously required applicants to file separately with SENER, the National Energy Commission (CNE), the National Energy Control Center (CENACE), and the Federal Electricity Commission (CFE). The CNE published in August 2025 an Agreement establishing the technical and financial requirements for obtaining an interconnected self-consumption permit in that capacity range, but the single institutional channel that the VUA now provides was still missing.

The binding deadlines under the new framework are: 20 business days for the resolution of the Energy Sector Social Impact Assessment (MISSE, by its Spanish acronym), 30 business days for the CNE to issue the generation permit, and 10 business days for signing the interconnection agreement with CFE, according to guidelines published by SENER. CFE itself had 30 business days from the date of entry into force to incorporate its metering and surplus energy purchase procedures into the platform. Applicants with proceedings initiated under the prior framework may migrate to the new simplified process. For intermittent generators, such as solar and wind plants, the framework requires backup through battery energy storage systems (BESS), formally incorporated into the national electricity framework in the CNE's model contract of March 2026.

The VUA targets large industrial and commercial users seeking to generate clean electricity on-site, a segment with growing weight in the operational costs of Mexico's manufacturing sector. The administrative simplification aligns with the goal of the 2025-2030 Sectoral Energy Program to raise clean electricity generation from 24 to 38 percent by 2030.
