Battery-Cell Testing Delivers Data Every Renewable-Energy Project Needs

Custom content for DNV GL by Utility Dive's Brand Studio

Within large energy storage and hybrid renewables projects, batteries are a high-cost investment. Those that degrade sooner than expected limit a project’s financial viability, negatively impacting the overall business case. 

Yet, with investor expectations on the line, project managers must be able to predict expenditures with accuracy. Battery warranties provide project risk mitigation by guaranteeing a certain energy capacity throughout the project term. But warranties aren’t always good indicators of future functionality and don’t address battery technology risks. 

In this playbook, we look at the importance of batteries in large renewable energy projects and describe in detail the DNV GL modeling process. By the end of the playbook readers will:

  • Understand how battery life ensures positive outcomes in renewable energy projects
  • Learn that battery warranties don’t provide the level of assurance about expected degradation
  • Understand how battery cell testing provides assurance
  • Discover DNV GL’s Battery XT and its Battery Scorecard
