The Democratization of Energy Jay Marhoefer CEO and Executive Manager Intelligent Generation LLC June 17, 2010
Tonight’s discussion • Overview of the electricity sector • The challenge of renewables • Intelligent GenerationTM and the democratization of energy
The obligatory plug • Intelligent GenerationTM is an integrated hardware/ software platform that democratizes how clean energy is produced and distributed. • The optimizer is a smart box that acquires electricity for a building when it is cheap or free and stores it in a battery for later use during peak times. It buys low and sells high. • The network forms a virtual power plant from the optimizers. It provides immediate, reliable power to utilities when it is most valuable. • The optimizer and network, when combined, can triple the cost savings of solar energy and cut the payback time in half.
Questions I hear • Why aren’t the wind turbines spinning when it’s a windy day? • Why can’t we run everything on renewables and use fossil fuels or nuclear power for backup? • Will a smart national electricity grid solve our problems? • Will solar ever work without subsidies?
It’s a little more complicated • Types of power companies • IOUs (investor owned utilities) • IPPs (independent power producers) • Wholesale power marketers (e.g. Exelon) • Munis and co-ops • Load generating vs. “wires and meters” • ARES (alternative retail electricity suppliers) • Regulators • FERC (Federal Energy Regulatory Commission • PUCs (state public utility commissions) • ISOs/RTOs (regional transmission organizations, e.g. PJM) • Other stuff • Baseload/load-following/peaker • RPS (renewable portfolio standards) • Deregulation For starters…
Which leads to 3 challenges • Availability/reliability • Nukes, coal and natural gas are steady • Wind and solar are not • Resource management • Grid was built to be one-way • How to match demand with (variable) supply? • Inertia • Nuclear plant: 5-7 days from cold start • Coal plant: 3-5 days • Load following natural gas plant: 30-90 minutes • Pure peaker: 15 minutes • Wind: 10-30 minutes • Solar: instantaneous
…and so did price volatility • Moral • Wind blows most when you need it least (winter nights) and least when you need it most (summer days) • Wind’s volatility necessitates more high value ancillary services (storage, voltage regulation, spinning reserve) • Wind potential is greatest in areas far away from major cities (other than offshore)
What about a national grid? • Probably won’t happen • Politics (see next slide) • Shifting demographics to Sun Belt • Low wind • Not aligned with regional transmission groups • Cost of new transmission (tens of $ billions) • Property rights
What about solar? • 92% of Americans think it’s important to develop solar energy and incorporate it in the U.S. electricity system Source: 2009 Schott Solar BarometerTM • But…long payback periods and high upfront costs • 15+ years even with 30% federal tax credit • 10+ years even with tax credit and $300/MWh REC
So what’s the answer? Demand side management Supply side management Demand
Reshape electricity demand Demand side management Demand
Reshape electricity demand Demand Solar
Reshape electricity demand Purchased off-peak /wind power stored in battery Demand
Reshape electricity demand Resulting purchased electricity Demand
…by democratizing energy • A managed network of distributed renewable generation and storage • 100,000 networked buildings is equivalent to bringing a small nuclear plant online immediately • Enormous market power even at 5% of total generation (see Texas) • The “Holy Grail”: consumer participation in the wholesale electricity market
Other possibilities • Smart grid • Plug-in hybrids • Fuel cells
Smart grid • Focus has been on demand-side management and investor-owned utilities • What consumers like • Real time pricing • Rewards for peak time reductions • What consumers don’t like • Utility control of “smart” appliances (HAN)
Plug-in hybrids • Potential storage capacity is formidable • 10 million PHEVs could store 100,000 MWh (enough to power California for 2 hours) • “Charging” side makes perfect sense • Excess capacity and cheap electricity • Discharge side is problematic • Peak times coincide with commute home • Higher and better use • Reducing greenhouse gas emissions? • Getting US off foreign oil?
Fuel cells • E.g., the “Bloom Box” • Darling of the cleantech VC crowd • $400 million invested to date • Reliable on-site production of electricity • But… • Won’t be affordable for 5-10 years • Needs a hydrocarbon (e.g., natural gas) • What happens in winter when the cost of natural gas is 6x?
Summary • Hardware costs are coming down • Solar • Batteries/storage • PHEVs are coming • Legislation (RPS, PACE) is driving adoption • Lack of integrated vision • Doing what’s cheap (wind) vs. what’s smart • Those who democratize energy will reap the major benefits
