Energy costs in the data center • Energy costs are emerging as the second highest operating cost (behind labor) in 70% of data centers worldwide* • 1MW data center consumes 160M kWhrs of energy over 10 years – Equivalent to energy consumed by 1,400 typical U.S. households in that same amount of time – UPS electrical losses typically account for 5-10% of energy usage**
• 80% of CEOs view sustainability as impacting brand value***

Data centers have large battery banks that often sit unused • The UPS is vital technology for any data center, providing critical backup power to ensure business continuity in the event of an outage • Outages are infrequent, which often renders the battery an underutilized asset

The adoption of lithium has created the opportunity for the UPS to serve dual purposes 1. Traditional critical power backup • Customer defines the minimum backup time required to protect critical loads • With a longer life and 8x the cycle rate compared to traditional VRLA batteries, lithium enables new ways to use the UPS and batteries

The adoption of lithium has created the opportunity for the UPS to serve dual purposes 2. Grid-aware energy storage device • Peak shaving discharges at times of peak demand to help avoid or reduce demand charges • Time-of-use optimization shifts energy consumption to avoid peak time usage • Grid support services, such as frequency regulation, further help grid operators meet the explosive growth in demand from data centers
Wave 1
Wave 2
• Data center has control of their energy, choosing how much capacity to offer and when

Eaton conducted a technology demonstration of a UPS as a DER for PJM* Technology demonstration goals • Provide frequency regulation (WAVE II) using the UPS AND demonstrate protection of the load in presence of a utility outage
UPS PJM RegD
• Self-score the UPS as a DER providing frequency regulation
*PJM is a regional transmission organization serving 13 states and the District of Columbia.

Implications of dual-purpose UPS are enormous for the grid and data center •
Lower demand and peak time charges utilizing existing asset and further clean energy goals
•
Create new revenue stream, lower overall energy costs and still serve as foundational backup power solution
•
Help reshape power generation with large battery banks that can dispatch instantaneously to better meet short-term spikes in demand
•
Estimated payback period is 3-7 years for the customer

Electric Power Research Institute (EPRI) Field Trial Eaton innovated an intelligent residential circuit breaker: the UL-listed device enables smart energy management across the home’s many connected devices
•
EPRI is in the process of completing a field trial (Phase 1) with 12 electric utilities across the U.S.
•
The field trial includes the demonstration of nearly 300 EMCB devices installed in residences and commercial businesses.
•
All project objectives of Phase 1 were satisfied, which completes requirements of the field test.
•
Key findings from the Phase 1 test included hardware and software changes to improve performance and scalability, are being incorporated into the commercial release.
