our Technology: Mobile energy storage transmission (MEST)

Gridspan Energy is pioneering development of a new system for electricity delivery, mobile energy storage transmission (MEST), with the goal of advancing energy access and security for island communities.


Mobile energy storage transmission (MEST) is an innovative solution which complements the shortcomings of conventional electricity transmission; specifically, the techno-economic inefficiencies of subsea cabled transmission. This novel electricity delivery model uses mobile energy storage units (MESUs) to transport electricity from one market to another by means of conventional freight vessels and infrastructure. In essence, MEST is a flexible alternative to conventional transmission that utilizes freight logistics, energy storage technology, and regional electricity price differentials in order to connect markets separated by large bodies of water or other substantial geographic features.
