Dispatch Ability

Subtitle: But Very Little Account Ability

UN Dispatch, On Day One, and Grist “are partnering to discuss ideas the next president can adopt to take on climate change.” As After Gutenberg readers can tell you, such discussion is critical if we are to make any effort to save life on the planet as we know it and get off coal.

Centralized power production in the United States and throughout the world historically has used a “sledgehammer” approach to power production, i.e., two-thirds of the energy consumed to create electricity is lost in the conversion process. And, the ongoing thinking would seem to be, “No matter. We just will blow the tops off some more mountains and keep on polluting the atmosphere with Green House Gases.”

Comparing Conversion and Distribution Efficiency
“It’s gone before you even knew it was there: As energy is unlocked from fuels at power plants, two-thirds of the energy consumed to create electricity is lost.”

The introduction to the discussion made only indirect inference to the climate crisis brought about by anthropogenic emissions, e.g., referring to Dr. Jim Hansen as a “New Age Paul Revere” because 20 years ago he attempted to warn federal policy makers. The first talking point was decentralized energy production.

Decentralized energy production through use of renewables (roof-top solar as well as solar farms, together with geothermal, tidal, and wind) can be transferred across our national grid to areas where it is needed from areas with higher productivity and/or lower need, which would change on a dynamic basis. This would eliminate centralized generating facilities as “targets” for terrorists, and eliminate the “control mentality” of large, centralized for-profit utilities.

A panel of experts, i.e., Grist writers Kate Sheppard and David Roberts; President of Climate Advisers Nigel Purvis; and Timothy B. Hurst of Red, Green and Blue and EcoPolitology, responded. Kate Sheppard started the discussion with an observation that farmers along the Delaware Bay, where there is “great wind capacity”, “would love to build wind turbines and start selling back to the grid, but they’re prevented by state laws.”

Although some states, notably California, have taken initiative to establish more environmentally sound energy policies, in her example, state policy prevents “not only a tremendous opportunity to become energy independent and to curb emissions, but also an economic opportunity for individuals and small businesses.” Shepperd does acknowledge some lack of federal policy, yet her focus primarily is on incentives.

Our ‘elected representatives’ in Congress repeatedly have failed to pass tax credit extensions for renewable energy. Indeed, important tax incentives for renewable energy are set to expire at the end of 2008. Proposed renewal includes a 6-year extension of the investment tax credit for solar energy; a 3-year extension of the production tax credit for biomass, geothermal, hydro power, landfill gas, and solid waste; and a 1-year extension of the production tax credit for wind energy… “The House has passed a $54 billion tax package repeatedly, but it’s failed in the Senate six times now,” carps Kate Sheppard.

Subsequent discussion picks up on this theme. Grist writer David Roberts improves the discussion by suggesting, “What is needed is a combination of regulatory reform and investment.” More importantly, he refines the discourse by discriminating between types of decentralized energy production.

Keep in mind that there are two kinds of decentralized energy. One is solar panels, small wind turbines, combined heat and power systems, geothermal heat pumps, and other sources of energy that can be owned and operated by communities, business, or individuals.

The other is utility-scale renewable power farms, mostly wind and concentrated solar (CSP). These are large and centralized insofar as they clustered together, but they are decentralized in that they are made up of multiple independent units. They are, in the jargon, modular.

Both have their merits — 207 merits, according to Amory Lovins. A system based on some mix of the two would get you graceful failure (individual units can go out without imperiling overall supply), safety (it’s difficult for terrorists or natural disasters to take out power plants that are spread out), dispatch-ability (it’s almost always windy or sunny somewhere in a large geographical area), and speed (units are smaller and cheaper and thus can be built more quickly).

Speaking of merit, I have yet to see a suggestion of merit on how to keep the crackers hap-hap-happy, while performing an ‘ecocidal‘ intervention, a.k.a., Sustainable Utility-Scale Energy Supply. Nor did the idea of Explicit Carbon Accounting enter into the discussion.

    BlueWater Wind and Delmarva Power just signed a deal to create North America’s first offshore wind farm.

    off-shore wind farm

    Nothing is set in stone yet (there are backout clauses in the contract) but the $800m deal could power 50,000 homes – and their EVs – using 70 windmills off of Rehobeth Beach by 2012.

    According to ABG reader GoodCheer, who sent a tip in before anything was officially announced and seems to have the goods, these are the details:

    - Delmarva Power will buy all production up to 200 MW @ 0.0968 / kW-h

    - Farm size will be determined based on how many other customers BlueWater can drum up, up to a maximum of 600MW.

    - Location will be 11.7-17.9 miles offshore, ENE of Rehobeth, DE.

    - Proposed structure is monopile driven into the sand / gravel bottom (prehistoric flood-plane of the Delaware River), 30 m in.

    - Turbine supplier TBD.

    There’s more at Delaware Online.

    Speaking, one might surmise, for Big Eddie,since she argues that “a purely local approach would double or triple costs” Gar Lipow has a Q&A for the Gristmill.

    Q. Aren’t long-distance transmission lines even more expensive?

    Not than doubling or tripling generation. Also very high prices quoted for transmission installation and maintenance conflate transmission and distribution. In the U.S., long-distance transmission costs are about half of distribution.

    Maintenance is even a smaller percentage. For example, a few years ago Western Washington suffered a major outage where wind storms took down both transmission and distribution. Long-distance transmission was mostly up within 24 hours, whereas distribution was fixed over the course of almost two weeks.

    Even though transmission is much more expensive to build and repair per mile, distribution requires many times the line miles. Transmission is point to point, or perhaps a few points to a few points. Distribution has to branch out to ever county, municipality, unincorporated area, and ultimately to every home.

    Q. Don’t long-distance lines reduce reliability?

    Not if they are modern High Voltage Direct Current lines. The most common HVDC type installed today actually can help guard against spikes and improve power quality.

    Q. Aren’t HVDC lines an environmental disaster?

    Not compared to coal and natural gas generation. But they can be installed in a much more environmentally benign way than at present.

    It has been suggested that we use existing railroad rights of ways for long-distance HVDC transmission — both as part of electrifying freight rail, but also as a way to create a true national grid without harming wilderness.

    Ultimately we need to remember there is no such thing as zero impact electricity. There is no Kilowatt fairy, no BTU bunny. Efficiency and renewables, including transmission are the lowest impact energy sources we know of.

    Q. Won’t demand shifting in a smart grid make long-distance transmission unnecessary?

    Demand shifting for a few hours or even a day won’t compensate for monthly variations in production. Even on a day-to-day basis, long-distance transmission is probably needed to produce a smooth enough production curve for smart-grid demand shifting and electricity storage (including vehicle to grid) to match.

    Q. Don’t most such variations match local seasonal peaks? That is, isn’t wind strongest in winter in cold climates, and sun strongest in summer in hot ones?

    If we were just changing electricity supply this would be valid. But climate control has huge potential for both efficiency improvements and non-electrical renewable supplies. Improved insulation, weather sealing, air circulation, along with ground source heat pumps can reduce demand. Direct solar heating (in commercial buildings and multi-unit residences cooling) also has significant potential. Dollar for dollar, these save or provide more energy than renewable electricity.

    This does not mean we don’t need renewable electricity. By the laws of physics, doing more with less won’t ever extend to the point where we can get something for nothing. But it does mean that renewable electricity only makes sense in a context where we are also massively investing in efficiency improvements and direct solar heating. These efficiency techniques will reduce seasonal variation in electricity demand.

    Speaking of incentives and disincentives, Big Eddie is known for not playing well with others. For example, with Lord Dumpling.
