Overview of a battery storage system

Who can benefit from battery storage?• Small business owners

• People on medical assist devices (non-critical)

• People who cannot or will not use generators

• Commercial accounts – reduce demand charges

• Areas vulnerable to extreme weather events

(shore & resort properties)

• Seasonal or 2nd home backup power & security

• Small business owners

• People on medical assist devices (non-critical)

• People who cannot or will not use generators

• Commercial accounts – reduce demand charges

• Areas vulnerable to extreme weather events

(shore & resort properties)

• Seasonal or 2nd home backup power & security

Battery storage landscape is changing

Advantages of BSS over generatorsEliminates:• Carbon emissions• Carbon monoxide poisoning risk• Eliminates noise• Need for fuel storage• Fuel escalation risk• Risk of equipment theft

Advantages:• Multi-faceted value• Significantly lower service time & costs• Can be sited indoors and in locations where

generators are not allowed

Due to fossil fuel use and costs, engine based generators willremain mainly for back up power

Regulatory Landscape

Primary Codes and standards:• NFPA70 - National Electrical Code

• UL9540 – Standard for EnergyStorage Systems and Equipment

• Many UL Sub-Standards (UL1973– Stationary Batteries, UL1741 –Inverters)

• IEEE1547 (Grid Interconnection) &IEEE2030 (Smart Grid)

NEC areas of key focus for battery storage

Scope defines a battery storage system

Set definitions

Example “Storage Battery”“ A battery comprised of one or more rechargeablecells of the lead-acid, nickel-cadmium, or otherrechargeable electrochemical types.”

Wiring and equipment supplied with batteries

Over-current protection

Means of disconnection

Insulation by specific type of batteries

First responders concerns

With more extreme weather,more homeowners now wantback up power (Irene, Sandy,2014 Winter Polar Vortex ...)

More people working fromhome offices and carryingpower usage to extremes.

Fire response will not know ifthere is a backup powersource. Safety for firstresponders must beconsidered in the installationprocess.

Extreme weather, and summer peakelectricity demands disruptingbusinesses who now want back uppower.

Commercial fires can destroy one ormany stores along busy corridors.Fast spreading fire often start in therear and travel with lightning speedtoward the front of the store.

Grid power and any secondarypower supplies is the first thing thatmust be disconnected so firefighterscan search for trapped victims.

When AC systems are on backup powersystems, and that backup system is notknown to fire departments, the AC systemcan restart and change the fire conditionsinside the burning building.

Fires have been sucked across vastdistances by the return flow of AC systems.

This can also compromise the roof structureand cause a collapse that may trap civiliansand firefighters.

Proper warning labels protect first responders

A most important consideration at all times

Communicate with all concerned parties

1. User/owner of the battery storage system2. Property owner if not same as user3. Property insurance issuer considerations4. Homeowners associations restrictions if any5. Local township for permitting and inspection6. First responders needs

Important for the installer:1. Customer satisfaction2. Strong word of mouth3. Referrals
