Ensign’s EnPower Battery Energy Storage System (BESS) is an easy solution that is powerful in its performance. The battery is paired with a proactive energy management system to deploy and store energy to use in combination with traditional generator power.
Using robust algorithms, BESS monitors the power demand of the rig and optimizes the power generation to automatically turn gensets on and off and deploy the battery as needed. The result is greatly increased generator efficiency, reduced power limits, and optimal fuel efficiency without sacrificing drawworks speed.
The lithium-ion batteries of the BESS are designed to last in rugged drilling environments and can be combined with highline power, diesel, natural gas or bi-fuel generators.
What’s more, with superior transitioning and load-levelling between the battery system and generators, BESS enhances the rig’s power performance and fuel efficiency.
