Battery Storage: 240 GW Global Capacity by 2030*
Grid-connected energy storage market is set to “explode” to an annual installation
size of 6 GW in 2017 and over 40 GW by 2022
Stationary Energy Storage will grow to $2.8 Billion annual market in 2020
Batteries for Micro-hybrids will grow to a $6.1 Billion annual market in 2020
Global market for energy storage for will grow to 1,040 GWh by 2030 (>$400B)
Energy storage is the “Holy Grail” in addressing the intermittency problem of renewables
Battery storage solutions are a “game-changer”
Texas utility Oncor will seek state regulatory approval for up to $5.2 Billion in distribution
grid-connected batteries, with deployment set to start in 2018 – 15GWh of batteries!

Key Question: What Are Barriers to Widespread Adoption?
1. Initial Cost – Minimize financial risk, accelerate payback time, open up the market size
2. NPV of cost and benefits – $/kWh throughput, recycling value (or cost) at end of life
3. Validated Performance – Will they last 10 years? Bankability. Replacement costs. Future-proof.
4. Safety and Acceptance – Customers, Regulators, and Environmentalists; On-site permitting
5. Connect Multiple Value Streams – Improve ROI and drive faster adoption; more power, more life

Factors Impacting Adoption - Analysis
Li-Ion
HP, high life
Mid-grade
HE, low life
Cost varies $350-
$750/kWh
Tesla disruption
Exotics
Flow, Zn, Fe, V,…
Promising low
cost in the future
Advanced Lead
$150/kWh now
Lets look at the
model more

Typically used for
grid-scale, but not

Payback time
more important in
behind-the-meter
applications –
minimizes financial risk
Cycle life plus
calendar life (can
Li-Ion last 10
years?)
Life at high rates
is also important

Battery-specific Analysis by Application Profile
6
A detailed analysis of the specific application is required to
determine the NPV life-cycle cost
6-factor Analysis Provides Insights on Battery Chemistry & ROI
Iterative Cost Model
Reduced capacity over life vs. a fixed energy
requirement results in a higher DOD use
The higher DOD faster capacity reduction
Iterations calculate incremental and
accumulated capacity loss with more accuracy
The analysis introduces a “replacement event”
when the capacity is no longer meets
application need or at “end of life”
This analysis includes:
Cycle life
Varying Depth of Discharge with
capacity loss
C-Rate (power to energy ratio)
Round Trip Efficiency
Calendar Life
