Energy trading platform for LNG, natural gas, power, and renewable commodities

Oil and Gas Houston, Texas 51–200 employees Founded 2011 Privately Held

MEMS is a Houston-based energy trading subsidiary managing a diversified commodity book across LNG, natural gas, power, crude oil, and expanding renewables (solar, wind, sustainable aviation fuels, renewable diesel). The tech stack is enterprise-standard (Microsoft Office, Excel, Allegro, Horizon, Python, SQL) — typical for trading operations — but the active project list reveals operational friction: pipeline nomination data entry, P&L reporting reconciliation, and congestion forecasting are being treated as discrete engineering efforts, suggesting the platform lacks integrated workflow automation for core trading functions.
