A SUCCESSFUL PLS PROGRAM FOR “BEHND THE METER” CUSTOMERS WILL INCLUDE:

• INCENTIVES THAT ARE LARGE ENOUGH TO ENCOURAGE PRIVATE COMPANIES– $1,000 PER kW SHIFTED FOR CHILLER BASED PLANTS– $2,000 PER kW SHIFTED FOR PACKAGED ROOFTOP INSTALLATIONS

• SIMPLE PROGRAM DESIGN– MEASURE LOAD SHIFTED FROM PEAK– kW OFFSET METHODOLGY (2008 & 2012 utility programs)– MEET CA BUILDING CODE, TITLE 24

• ABILITY TO COMBINE UTILITY PROGRAMS

• CPUC/IOU’s REBATE PROGRAMS OVERLOOKING SCALE AND ECONOMIC DEVELOPMENT OPPORTUNITIES FOR ENERGY STORAGE IN CALIFORNIA

INCENTIVE LEVELS• OVER THE LAST DECADE THE VAST

MAJORITY OF INSTALLATIONS IN CA ARE IN PUBLICALLY OWNED FACILTIES

• PRIVATE FACILTIES (BEHIND THE METER) EVALUATE TECHNOLOGIES BASED ON THE RETURN ON INVESTMENT (ROI)

• PROPOSED INCENTIVE LEVELS WILL IMPROVE ROI SLIGHTLY, WILL NOT IMPACT MARKET DEVELOPMENT SIGNIFICANTLY

3

INCENTIVE LEVELS• FOR CHILLER BASED SYSTEMS THE

INCENTIVE NEEDS TO BE AT LEAST $1,000 PER kW SHIFTED FOR PRIVATE COMPANIES TO INVEST IN THE TECHNOLOGY

• FOR PACKAGED ROOFTOP TECHNOLOGIES THE INCENTIVE NEEDS TO $2,000 PER kW SHIFTED FOR PRIVATE COMPANIES TO INVEST IN THE TECHNOLOGY

4

PROGRAM DESIGN• FOCUS ON kW SHIFTED– EXTENSIVE ENERGY ANALYSIS

REQUIREMENTS WILL CAUSE SOME ENGINEERS TO AVOID THE PROGRAM

– THIS IS A LOAD SHIFTING PROGRAM, ENERGY USAGE IS FACTORED INTO THE PROCESS IN 2 WAYS:

– POORLY PERFORMING TECHNOLGIES WILL NOT PROVIDE SAVINGS TO THE BUILDING OWNER

– THE INSTALLATION MUST MEET CA CODE

• MEET CA BUILDING CODE5

COMBINE PROGRAMS GAIN PROGRAM EFFICIENCIES IMPROVING CUSTOMER ADOPTION – LESSONS

LEARNED

• 2008-2011 SCE PLS PROGRAM– $1110/kW Customer incentive (8-12 year ROI)– 3 TES system delivered in 3 years

• 2012 SCE EE/PLS PILOT (combine programs)– PLS combined with Energy Efficiency

• SCE HVAC Optimization PLS ($1800/kW + HVAC replacement EE rebates)• Construction costs are lowered, program admin costs reduced • 6 months, 15 TES Systems Qualified for Rebates - in construction phase• Commercial Lease Program added to offset capital investment

• LESSONS LEARNED• Rebates must achieve 3-5 year payback to encourage market

adoption• IOU customers have limited cash availability during economic

stagnation– OBF encourages energy measure without investment risk – SCE 2012 Pilot Program did not Qualify for OBF– Customer are willing to invest in PLS/EE measure with financing

PROGRAM DESIGN REQUIREMENTS FOR SUCCESS

• ELIMINATE ANNUAL ENERGY PENALTY (Sect. 4.1)– Why? This is a load shifting program, economics and code

compliance will eliminate inefficient systems.

• ELIMINATE REQUIREMENT TO REMAIN ON TOU RATE FOR 5 YEARS (Sect. 5)– Why penalize a building owner if he/she is still shifting peak

loads?

• INCLUDE COOLING TOWER LOAD FOR WATER COOLED PLANTS AS LOAD SHIFTED (Sect. 7.4)– For water-cooled chillers the cooling tower loads are also

shifted, need to be added to compressor efficiency to total the shifted load.

7

COST EFFECTIVENESS• PLS HAS GREATER COST AVOIDANCE VALUE FOR UTILITIES THAN END

CUSTOMERS – PUBLIC POWER UTILITIES ARE PURCHASING MW SCALE STORAGE AT $2000-$3000/kW

JUSTIFIYING INVESTMENTS WITH ROI MODELS– Public Power compares PLS investment against other utility solutions (peak

power, market energy investments over 20-30 year terms)– TRC utility models are not used for large scale utility asset purchases

• MW SCALE PROCUREMENT PROVIDES CONTRACTUAL, FINANCE, PRODUCT MFG, DESIGN, AND CONSTRUCTION EFFICIENCIES THAT REBATE PROGRAMS CAN NOT ACHIEVE IN ONE OFF DEPLOYMENT

• COMBINING PROGRAM FOR EFFIECIENCIES– PLS, EE HVAC REPLACMENT, DEMAND RESPONSE, SMART GRID INTEGRATION

• ECONOMIC DEVELOPMENT VALUE IS OVERLOOKED BY IOU PROGRAMS– ICE ENERGY MOVED BUSINESS HQ TO CALIFORNIA IN 2012 – intent to captures SGIP to $400/kW

economic development incentive (not allowed SGIP program participation – ICE ENERY RE-INVESTS ~$1000/kW of $2170/kW MW scale Energy storage purchase

• i.e., $10 Million dollars of a 10 MW project is reinvested in engineering, – ICE ENERGY COMMITTED TO LIGHT MANUFACTURING/TESTING OF ICE BEAR PRODUCT WITH 6 MW

ENERGY STORAGE PURCHASE BY REDDING ELECTIRC UTILITY IN JUNE 2012– CITY OF REDDING ELECTRIC UTILITY RECOGNIZES UP TO 50% OF ENERGY STORAGE INVESMTENT GOES
