ESSB SUMMER 2019

RENEWABLE ENERGY WITH ENERGY STORAGE SYSTEMS

BUZZ WORDS

• Retail Electricity

• Regulated vs Non-Regulated

• “Behind the meter”

• Microgrid

• Peak shaving

• Islanding

• Redundancy

• Resilience

• Sustainability2

WHERE ARE THE RENEWABLES?

WHERE DO WE NEED THE MOST POWER?

WHY SHOULD I USE AN ESS?• Contingency planning

• Power diversification

• Resilience from shock events and natural disasters

• Remote locations with scarce grid supply

• Energy arbitrage and protection against rising energy costs

• Maximize renewable energy efficiency (PV ramp, harvest excess energy, etc)

• Power quality issues (Voltage swell/sag/spike, frequency variations, harmonics, inductive noise etc., PV ramping)

• Sick of the power company, Island mode! 🤬🤬

• Sustainability

• Microgrid optimization 7

THE GRID LOVES ME• Immediately dispatchable compared to peeking stations (seconds vs hours)

• Frequency restoration

• Load following capability

• Ramp rate optimization compared to other renewables

8

THE GRID LOVES ME NOT

• Intermittent power delivery

• Voltage control and step-up XFMR tap changer variation

• Less effective on distribution systems with high inductive loads

• The infamous DUCK curve

• Vertically integrated utilities (regulated markets)
