What their customers say
Quotes from people at Mitsui's customers.
“Our work is built on data. We help clients read the market and act on it, whether that means hedging at the right moment or curtailing load when it counts. A strategy is only as strong as the partner who can execute it, and MEMS Industrial Supply consistently delivers on that front. They are flexible, they move quickly, and they understand that the right structure is the one that fits the client. That makes them a natural fit for the way we work.”
“MEMS Industrial Supply is a pleasure to work with. They're honest, deeply organized, and strategic in how they serve loads. MEMSIS was one of the first in ERCOT to adopt automated daily settlements, which materially reduced financial security requirements for my client. For large industrial users in ERCOT, they are an excellent choice.”
“The deals we bring to market are complex by nature. We specialize in weaving together retail supply with behind-the-meter generation, building layered structures for large industrial customers with sophisticated energy needs. What we've found in MEMS Industrial Supply is a team that meets that complexity with genuine depth. They understand the structures, they execute cleanly, and they bring the kind of thoughtful engagement that makes the work better at every stage. That's what a real energy partner looks like.”
“Scaling Bitcoin mining operations means managing a lot of moving parts, and retail energy supply is one of the most critical, so choosing the right supplier isn't a decision we took lightly. MEMS Industrial Supply has earned our trust since January 2025. Their team manages several ERCOT facilities for us, staying genuinely involved day-to-day: keeping billing accurate, making sure payments hit right, and staying on top of our collateral requirements without us having to chase them down. For a company operating at our pace, that kind of responsiveness matters.”
