BRINGING SAFE, RELIABLE ENERGY STORAGE TO GILLESPIE COUNTY
What is a Battery Energy Storage System (BESS)?
We use batteries everyday, from our mobile phones and laptops to electric vehicles and toothbrushes, and the same technology that powers our personal devices powers our communities through battery energy storage projects.
Energy storage projects provide back-up power to homes and businesses, limit power outages, make our electrical grid more reliable, and enable our communities to run on clean, affordable energy.
Energy storage allows electricity to be saved and used at a later time, when and where it is most needed, which contributes to both our grid reliability and energy security.
Battery Energy Storage Systems draw energy from the grid during times of low demand and discharge that energy back to into the grid as needed during times of high demand.
About The Project
Rogers Draw is an exciting, new 145 MW energy storage system proposed for Gillespie County, TX.
This project bolsters LCRA’s capacity to provide reliable and consistent energy to a region that experiences a 97% day-over-day volatility in energy demand, and cost of energy to ratepayers, compared to all other ERCOT substations.
Rogers Draw is the first storage project in the region and will not emit any smell, smoke, or noise pollution typically associated with industrial facilities.
There will also be no discernible impacts on traffic.
Rogers Draw Energy Storage Facility will use technology provided by Wärtsilä, an energy storage system provider with exceptional experience, quality and a safety record that includes zero failures across its network of facilities.
Having voluntarily subjected their battery storage system to a testing regime that exceeded existing standards, Wärtsilä demonstrated their commitment to safety and established a new benchmark for grid-level fire safety testing in the energy storage industry. This rigorous testing involved intentionally inducing a fire, revealing important information to the manufacturer, first responders and asset owners about how the system would react in the highly unlikely event of a cell failure and solidifying Wärtsilä’s position as a market leader in the manufacturing of safe, compliant energy storage systems. Their equipment has never experienced a failure or fire, but it features an internal fire suppression system as an added layer of protection and monitoring and predictive analytics softwares that can anticipate potential system failures up to a year in advance.
Industry Leading Technology
Site Overview
The Rogers Draw Energy Storage Project is sited to interconnect with, and support the Lower Colorado River Authority (LCRA) “Headwaters” Substation. The Headwaters Substation serves as the critical link between two LCRA transmission lines: Mountain-Hunt, and the Harper-Live Oak .
Together, these transmission lines provide reliable energy to Gillespie, Kerr, and Kendall Counties - over 120,000 American Households in the Heart of Texas. The 145-Megawatt Rogers Draw Energy Storage Project will maximize LCRA’s reliability and mission of providing reliable energy to the Texas Hill Country and beyond.

Multi-Stage Redundant Safety
Just like other energy sources, all energy storage projects must meet rigorous codes and standards to be permitted to operate, and Peregrine’s standards exceed requirements in multiple key aspects.
Peregrine has extensively reviewed applicable fire safety codes, participated in national, leading fire safety committees, and studied all fire incidents to date to create a best-in-class fire protection design standard for its projects focused on data availability and monitoring, predictive analytics, and redundant safety features at every level. The Rogers Draw facility will have 12 layers of protection solely focused on the prevention of fires and goes even further to provide detection, control, and notification to the emergency response team in the event of an incident.
The unincorporated town of Harper, TX is home to 1,250 residents and boasts an all-volunteer fire department who relies on a single 90,000-gallon-fire-water tank.
Rogers Draw will be installed with redundant fire suppression and support systems, as a benefit to the community – the Harper Volunteer Fire Department and Gillespie County Emergency Services will be granted access to an additional 50,000 gallons of fire suppression water.
Peregrine Energy Solutions will also offer comprehensive training to First Responders, including the Harper Volunteer Fire Department and Gillespie County Emergency Management services, to address emergencies at the facility.
In addition, $30 million in local funding will go directly to Gillespie County, Texas.
Community Benefits
On top of these economic benefits, Peregrine proudly invests heavily in the communities where operational and believes these communities know best as to where dollars are best spent.
