The **Megablock** is a new, pre-engineered medium-voltage utility-scale solution that integrates four Megapack 3 units with an onboard megavolt transformer and switchgear. This integration significantly reduces the need for separate substation infrastructure, lowering installation costs and complexity. Each Megablock delivers 20 MWh AC capacity, supports over 10,000 cycles with a 25-year operational life, and achieves about 91% round-trip efficiency at medium voltage, including auxiliary loads. It is designed to operate in extreme environmental conditions ranging from -40°C to 60°C. Tesla highlights that the Megablock can be installed 23% faster and can achieve a site-level energy density of 248 MWh per acre. The company claims it can deploy 1 GWh of storage in just 20 business days using this new system, enough to power approximately 400,000 homes in under a month[1][3][5].
