Peak shaving is the practice of discharging a battery system during high-demand or high-tariff periods to reduce a facility’s peak draw from the grid, lowering the demand charges or peak-hour energy costs that appear on commercial and industrial electricity bills.<\/p>\n\n

Why it matters for commercial energy costs<\/h2>\n\n

Peak shaving matters most at commercial and industrial scale, where electricity tariffs often carry a demand charge: a fee based not on total energy consumed but on the highest power draw recorded in a billing period, sometimes over just a 15-minute window. A single power surge can set the demand charge for an entire month. A battery discharging during that window keeps the metered peak below the threshold that triggers the higher rate.<\/p>\n\n

Residential users on time-of-use tariffs also benefit: the battery discharges during expensive peak-rate hours and recharges cheaply overnight. The financial case depends entirely on your local rate structure, so check your own tariff schedule before sizing a system.<\/p>\n\n

Peak Shaving in practice<\/h2>\n\n

Key numbers<\/h3>\n\n

A peak-shaving system typically performs one to two planned discharge cycles per day, targeting the demand window rather than running the battery fully down. Genixgreen LiFePO4 BESS<\/a> units run at a nominal 51.2 V and are rated for 6000+ cycles, scaling in parallel from about 5 kWh to 16 kWh for homes and into the MWh range for commercial sites. Usable energy is about 85 percent of nameplate: depth of discharge runs 80 to 95 percent, combined with one-way discharge and inverter efficiency of 90 to 95 percent. System round-trip efficiency for a full charge-and-discharge cycle is about 90 percent. Because peak shaving follows a predictable daily schedule, the 6000+ cycle rating translates directly into years of low-maintenance operation. A grid-connected peak-shaving setup must follow local grid-interconnection rules, so have a qualified electrician commission it.(Source: Battery University BU-808<\/a>)<\/p>\n\n

Peak shaving vs load shifting<\/h3>\n\n

Peak shaving targets the highest power draw spike, typically a brief demand-charge window. Load shifting moves energy consumption broadly from expensive hours to cheap ones. In practice, a commercial battery controller often does both simultaneously: it avoids the demand-charge spike (peak shaving) while also charging during low-cost off-peak hours (load shifting). Both strategies require a grid-tied ESS<\/a> with a controller that reads real-time meter data, and both yield savings that depend entirely on the site’s own tariff structure.<\/p>\n\n

How Genixgreen uses Peak Shaving<\/h2>\n\n

Genixgreen has built LiFePO4 storage in its own factory since 2011 and ships to 100+ countries, with local stock in Odesa for delivery across Ukraine. Commercial sites where peak shaving matters most use scalable Genixgreen battery racks that expand in parallel as demand profiles grow. LiFePO4 handles the predictable daily cycling that peak shaving requires, and stationary commercial installations are built to the IEC 62619 safety requirements for lithium battery systems.(Source: IEC 62619<\/a>)<\/p>\n\n
