Stationary battery storage and energy management for Liftra's production

Liftra wanted to establish whether a battery could improve the economics of the energy consumption in its production, at a site where a solar PV installation was already in operation. On top of this came an operational challenge: the power peaks from production put pressure on the transformer station the site is connected to, and thereby set a limit on how far consumption can grow. Leap Solutions began with a business case based on Liftra's own hourly metering data, modelling the total cost of electricity (spot price, tariffs and electricity tax) with and without a battery across a range of capacities and power ratings.

The analysis documented the savings potential in three mechanisms: retaining a larger share of the solar production for self-consumption instead of exporting it to the grid, shifting electricity purchases from the expensive hours to the cheap ones, and using the battery for peak shaving, where it covers the top of the production load and thereby relieves the connection point. On that basis, Leap Solutions handled procurement, electrical integration behind the meter and commissioning of a stationary battery system at Liftra's site.

The system is operated today through a software platform from Leap Solutions, which monitors the battery and automatically controls charging and discharging according to spot prices, solar production and consumption. On top of that, it keeps the power peaks down when production draws the hardest. The platform gives Liftra continuous insight into both the realised savings and the load on the grid connection.

From analysis and implementation through to operation, Leap Solutions has been responsible for the entire process. Today we supply the software that keeps the system optimised.
