Five Things To Remember

1. Net/Energy Available for Work” declining.2. AZ imports 90% of electricity fuels. No one knows

what fuel will cost in the future, can rise quickly. 3. Solar, wind have higher up-front but lower long-

term costs, less risk.4. Electricity production: from large, central-station to

distributed, closer to load; business models under growing stress.

5. Damages from “externalities” such as water and air pollution, mortality, lost work days, childhood asthma are known; a range of costs could be included in the “cost” of electricity.

Page 5: Az's energy current and future-climas-nov 2013-v4-final

Background: Key Concepts

ENERGY v CAPACITY Energy = kWh, MWh – usable energy Capacity Factor = output over time

Why is this important? Because power plants have different capacity factors: Nuclear: 93% Capacity Factor (CF) Coal: 80% CF Wind: 30-40% CF Solar: 20-23% CF (in AZ) Geothermal: 92% CF

Page 6: Az's energy current and future-climas-nov 2013-v4-final

Energy, Electricity and “Net” Energy Energy: liquid transportation fuels Electricity: coal, natural gas, nuclear, solar, wind, hydropower

Currently not much overlap, but will change as we “electrify” transportation with light rail, electric cars, etc.

Net Energy = the energy left after using energy to drill, mine, transport, compress, combust, build, etc.

Also called E-ROI (Energy Return on Investment) Energy costs are going to rise: Do we invest in renewables,

with higher capital costs, or fossil fuel plants, with increasing fuel costs and high Operation and Maintenance?

“Externalities” increasingly important: global warming, water scarcity; also enormous health effects from fossil fuels we’ve ignored for decades

Environmental justice issues: local, U.S., global

Page 7: Az's energy current and future-climas-nov 2013-v4-final

The easiest-to-getresources are extracted

first. Example: deepwater v. onshore

drilling for oil.

Page 8: Az's energy current and future-climas-nov 2013-v4-final

Energy Slaves? ~8 calories of oil embedded in every

single calorie of food delivered

Renewable energy (solar, wind) not as dense, not ‘on demand,’ need storage.

We will likely electrify transportation

One Barrel Oil = 25,000 hrs human labor

25,000 hrs human labor = 12.5 yrs work

At $20/hr = $500,000 of labor/barrel

Oil at $110/barrel = 6 cents/kWh, or 500 times cheaper than human labor.

What Is AZ’s Electricity Mix?

Total in-state generation: ~27,000 MW (27GW) Total in-state consumption: ~16,000 MW

40-50% coal ~30% natural gas ~22% nuclear ~4% hydro

AZ: less than 2% of electricity used in-state is solar Total in-state solar: 1,300-2,000 MW However, ~50% of the output is sold to California

AZ Corporation Commission (ACC) One of 7 states with a constitutional Comm’n One of 13 states with an elected Comm’n The ACC has absolute authority over energy policy Most states: Governor appoints Utilities

Commissioners In my experience, nearly every other state has more

transparency, and easier access to information. Complex process, need a lawyer or a lot of time,

energy and guts to participate meaningfully. Key: it’s all about underlying assumptions such as

fuel costs, discount rates, cost of capital, value of ‘externalities.’

APS’ RW Beck Study on the Value Of Distributed Energy

Operating Impacts and Valuation study

RW Beck study says the value of distributed solar is 7.9 to 14.11 cents/kWh in avoided costs for fuel, trans-mission, line losses, etc.

Page 21: Az's energy current and future-climas-nov 2013-v4-final

Why Do the Costs of Electricity Vary So Much? Different “capacity factor” for each type of

plant: solar generates electricity during the day, natural gas has high and volatile fuel costs, coal compliance costs are increasing.

How much are fuel costs increasing/yr? How much will nuclear decommissioning? How much will the cost of solar, wind and

other clean energy solutions decrease? What about water supplies?

Coal By The Numbers

U.S. utilities purchase ~$40 BN/yr coal $40 BN coal = $160 BN coal-fired

electricity $160 BN/yr in coal-fired electricity = $187

BN/yr in health damages alone, plus $530BN/yr total damages for life-cycle of

coal per Harvard School of Public Health Study

Coal’s Externalities / True Costs

Dr. Paul Epstein, Harvard study, Feb. 2011 “Full Cost Accounting for the Life Cycle of Coal”,

Coal-fired power plants produce 50% of U.S. electricity. Coal costs the U.S. $500B annually over its life cycle(extraction, transport, processing, and combustion)

•$74B in public health burdens in Appalachian communities•$187.5B from health costs of cancer, lung disease, and respiratory sickness in other parts of the U.S.•$29.3B from mercury impacts•$205B from carbon emissions’ climate impacts on land use, energy consumption, and food prices•$18B from the costs of cleaning up spills of toxic waste, the impact of coal on crops, property values, and tourism

Externalities would raise costs of electricity from coal-fired plants, from $0.10 / kWh to $0.28 / kWh, shifting it from one of the cheapest sources of electricity to one of the most expensive.

24 States Generate More Clean Electricity Than AZ! Why? Because the U.S. has nearly 6 times more wind

than solar – 60 GW wind v. 10 GW solar PV and CSP or Concentrating Solar Power).

In most other states, solar is far more expensive than in AZ because they don’t generate as much electricity per installed watt of solar.

Solar in New Jersey v. Arizona

New Jersey 1,119 MW of solar energy currently installed 2012: $1.3 billion invested Average installed price down 27% from last year.

Arizona 1,250 MW of solar currently installed 2012: $590 million invested Average installed price down 1% from last year.  

Why? NJ PUC committed to solar, Hurricane Sandy driving more clean

energy, higher rebates even though AZ solar generates electricity 20-23% of hours/year v. NJ 15% of hours/year.

CO River, Hoover Dam, Lake Mead: Water and Power Lifeline for 30 Million Lake Mead levels at ~45%

In 2010, was at 1,084 feet, the lowest since 1956 Level will hit the lowest since the 1930’s when dam was built Power generation is ~23% lower; power reduced by 5.7 MW for every 1 foot loss in the

lake level Power output reduced from 2,080 MW to 1,617 MW Every 1 MW power loss = ~ 1,000 homes

Experts don’t know what will happen if water drops below 1,050 Turbines could be damaged if not enough pressure so would be turned off. “If Lake Mead were to drop to that level, it would be devastating,” Joseph Mulholland,

Executive Director of the AZ Power Authority, which markets Hoover power. Climate change means less water and more evaporation.

Study by Tim Barnett and David Pierce predicts that by 2017 Lake Mead level will be too low for power production; and by 2021 a 50% chance of going dry.

Hoover and Glen Canyon Dam on Lake Powell handle 80% of peak power regulation in 5 Western states and parts of 2 others.

Electricity from Hoover Dam: 28.5% Metropolitan Water District of Southern California 23% Nevada, 18% AZ; remaining to Los Angeles and others.

Water To Cool Power Plants = 50% of U.S. Water Withdrawals The U.S. Geological Survey (USGS) reports that

53% of all fresh surface water withdrawn for human use in 2005 was used by power plants.

In 2009 the water footprint of U.S. electricity was approximately 42 gallons per kilowatt hour (kWh) produced.

Average U.S. household requires 39,829 gallons of water for electricity; five times more than direct residential water use.

13% of total electricity used to move, treat and heat water.

6,000 – 8,000 MW x $2.5 to 3 million/MW = $15-18 BILLION

To put this in perspective, AZ spends $2-3 BILLION/year on fuel

Solar would displace fuel costs forever!

If fuel costs stayed at $3 billion/year, and solar costs continued to fall, AZ could pay for the build-out with 5 years of fuel payments!

Cracks in the Current System Germany: 59% renewable peak, grid fine. 10/30/13

Solar/wind means less power from coal, nuclear; don’t “cycle.” Solar steals peak demand, along with peak profits.

Germany's RWE: “massive erosion of…prices caused by solar PV” “may…threaten the company's survival.” RWE's share price has lost one-third of its value over 3 years.

Coal replaces natgas when the cost is $3.50-4.00/MMBtu. Natgas at $3.61 on 11/12/13.

Net Metering is a big battle in many states: Idaho, Georgia, California, Texas and Colorado. Idaho and Georgia PUC made pro-solar decisions. AZ still in the balance, likely to add $20/month fee for solar.

Cracks in the Current System Lots of talk about the utility “death spiral” and the need

for a new business model. Utility profits based on volume rather than value. Very high fixed costs for utilities:

Nuclear has high labor costs; coal has high compliance costs; production costs rising.

As more people put on solar, less people to pay for coal.

Fukushima: Huge unresolved issue with spent fuel that needs to be moved; very difficult and potentially dangerous. 23 U.S. nuclear plants with same design.

Cracks in the Current System Solar is ‘stealing’ peak demand, which is

where utilities make the most profit Once renewables are paid for, “almost zero”

operating cost.

What Are the Obstacles to More Clean Energy in AZ?

Determine what is a solar kWh “worth”? 4 cents (utilities) or 22 cents (solar)

Monopoly utilities “own” geographic territories, so reduced competition.

AZ’s Renewable Energy Standard is very low. Utilities currently lose money on clean energy and

energy efficiency, so have no financial incentive. Economics of solar/wind different than coal, nuclear or

natural gas: clean energy costs are all up-front, while fuel-related costs are ~70% of lifetime fossil plant costs.

Page 66: Az's energy current and future-climas-nov 2013-v4-final

What Are Possible Solutions? Provide access to the Grid: Community Solar,

who owns? Provide access to Capital

Support PACE (Property Assessed Clean Energy) Support Extension of Federal Section 1603 Cash-in-Lieu-

of-Tax-Benefit (30%) Solar securitization happening

Utilities: rate-base (own) solar and get a higher rate of return for clean electrons

Include Cost of Environmental/Health Externalities Pay now or pay later

Consider re-evaluating “avoided cost” for utilities Doesn’t include value of water, health benefits Doesn’t include time-value of solar

Page 67: Az's energy current and future-climas-nov 2013-v4-final

What Are Possible Solutions?

Increase the REST from 15% by 2025 to ? Level the playing field for subsidies Use Life-Cycle Analysis When Modeling, Use a Range of

Costs/Risks/Discount Rates Allow the use of Master Limited Partnerships for

clean energy – not just oil, gas and biofuels. Increase Pilot Programs for Solar Hot Water,

Combined Heat and Power, Biodigesters etc. Solar Hot Water is a HUGE unused resource.

Section 1603: $581 Million Worth of Projects in Arizona To Date Section 1603 is a cash grant in lieu of taking a 30% solar tax

investment tax credit.

Section 1603 expired on 12/31/11.

AZ has rec’d $581 million in Section 1603 projects, mostly

solar. http://www.treasury.gov/initiatives/recovery/Pages/1603.aspx

The Solar ITC (Investment Tax Credit) expires in 2016 and should be extended.

Regional Clean Energy: What Does It Mean? Lots of studies going on right now, very complex

issues in predicting what will happen if power is shared regionally

April 2013 report on Energy Imbalance Market (Western states) that sharing power regionally would save $94-$294 million the first year. Why? Because when utilities share power they need less

‘reserves’, i.e. backup power. With more geographic diversity and in greater amounts,

solar and wind are more reliable. Bottom line: sharing power can reduce a utility’s

need for more power plants; thus reduce profits.

Wrap-Up

AZ in-state electricity: 2% solar, 50% coal AZ sends $2.5-3 billion/year out of state for

coal/natural gas. Net Metering debate: what is the 'value' of a

solar kWh? Clean Energy needs:

Access to capital Access to the grid Stable, predictable policies
