What changed and who it applies to
What changed
Any new demand, or expansion, that requests connection to the Mercado Eléctrico Mayorista and amounts to at least 0.5% of the system's average demand becomes an Extra-Trend Demand (XDEM). To connect, it must submit a supply plan with at least 80% of energy from new production and backed by new firm capacity covering 100% of its consumption if it is a production plant, or 115% if it is a data center. Applications already in process have 60 days to comply. verif Sep 25, 2026 ↗

Who it applies to
Anyone who wants to connect a large electricity load: data centers, mining companies, industrial plants. And on the other side, those who sell generation: each of those loads has to contract new energy and backup capacity, whether solar, wind, batteries or thermal. thesis Sep 25, 2026

Our reading
thesis · R16 Large new consumption stops hanging off the existing grid: it pays for its own generation. For the data center investor the cost of entry rises, because it needs 115% of its own capacity. For the generation developer it is the reverse: every large project that arrives brings a new-energy contract with a date, and that ties in with Res. SE 257/2026, which lets renewable parks move to the market between private parties just as these buyers appear. thesis
