Pumped hydro units have been installed in Europe from 1970 through the 1990s incombination with nuclear build-out

Matching inflexible generation to load is not new

Pumped hydro energy storage is used worldwide for multiple applications:• Generation on peak• Frequency regulation• Spinning reservesLike pumped storage, today’s storage technologies should be valued for the fullspectrum of applications that they can provide.


Storage addresses challenges across the grid

Generation

• Underutilized assets• Carbon emitting resources• Intermittent renewables• Volatile fossil fuel costs

Transmission &Distribution

• Congestion management• Capital intensive

infrastructure upgrades• VAR/Voltage management

End Users

• Rising energy costs• Rising peak demand

charges• Sensitive equipment• Outage management

Market Operations

• Perfectly balance real time supply and demand• Manage frequency regulation• Maintain adequate reserve capacity


Select developments…• Tesla Energy introduced energy storage products for residential and grid-scale applications

• Hawaii house and senate passed bills setting goal of 30% renewable energy by 2030, 70% energy by 2040,to 100% by 2045

• White House “Quadrennial Energy Review” (QER) coins new phrase “TS&D” for transmission, storage anddistribution, underscoring the potential for storage to play a major role in the nation’s infrastructure in futureyears

• Capacity markets storage favorable developments: PJM Interconnection planning to include storage as acapacity resource

Energy storage market is growing

Ambri storage will enable higher levels ofrenewable penetration than otherwisepossible by providing:

• Ramping (smoothing) capability to addressrenewable intermittency

• Time-shifting of generation to match supplywith demand

• 24/7 renewable power capability, providingenergy independence from volatile fossilfuel markets

• Energy resilience during civilian gridoutages

• Access to energy in remote locations

Growing opportunities for renewable + storage pairings

Ambri storage can help manage frequency deviations caused by increasinglevels of solar generation.

Solar and Ambri storage can be paired together to create systems run on100% renewable generation at attractive returns for project investors


The benefits of Ambri long duration battery storage

+ =

• 1 MW battery on Hawaii reduced variability of grid frequency by 30-50%across a day.

• Ambri will meet all frequency regulation requirements and will shift solaroutput to periods of high demand.

Case study: Energy Storage at Joint Base Cape Cod

Days with Net Positive Critical Load at VariousLevels of Ambri Storage and Renewable

Generation

Peak Monthly Demand for complete basewith/without 16 MWh Ambri system

• Energy independence: JBCC can be independent of the civilian grid 98% of the timewith 40 MWh of energy storage plus onsite renewables (JBCC has a peak load of 7.5MW)

• Electricity cost reductions: JBCC can save between $2M and $4M over the lifetime ofthe battery by reducing the base’s peak demand and demand charges and optimizingtime-of-use rates.

With 40 MWh of EnergyStorage, JBCC can be

independent of the civiliangrid 98% of the time

With 80 MWh of EnergyStorage, JBCC can be

independent of thecivilian grid 100% of the

time


Integrating renewables creates escalating challengesHawaii’s experiences are a learning laboratory for rest of world

Increasing wind & solar adoption creates grid challenges and storage opportunity:1. < 5% adoption: grid accommodation without great difficulty2. 5% to 20% adoption: grid challenged to regulate frequency and manage renewables ramp; short

duration, less than 1 hour, storage particularly valuable3. Higher adoption: extensive renewable curtailment called upon, fossil back-up utilized; multi-hour

storage valuable Largest market opportunity, requires low-cost and long-lifespan storage

DG = distributed generation (mostlyresidential solar)

Increasing PV deployment is straining distribution circuits Significant wind energy is being curtailed

HECO: total wind energy accepted and rejected by time of day
