California takes two big steps toward more renewables and EV’s

by Silvio Marcacci.

California already leads the United States in most measures of the clean energy economy, but two new initiatives by the state’s grid operator could ensure the Golden State’s electricity system can handle far more renewables, electric vehicles, and power demand.

The California Independent System Operator (Cal-ISO) announced two plans last month to help it integrate EV’s as grid balancing resources, increase demand response and energy efficiency to shave peak demand, and coordinate long-term grid reliability as more renewable power generation comes online.

Either of these initiatives by themselves would be big news for the cleantech industry, but taken together, they hint at the true potential of California to blaze a path toward a clean energy future.

Shave Consumer Power Demand To Boost Grid Reliability

Cal-ISO started in mid-December by releasing the Demand Response and Energy Efficiency Roadmap, a blueprint intended to help “flatten” peak consumer electricity demand while enabling grid operators to better incorporate distributed generation and energy storage within three years.

The plan also takes a long-term approach toward replacing the retired San Onofre Nuclear Generating Station, as well as the potential retirements of 6,000 megawatts of older coastal power plants at risk of closing starting in 2017 when regulations limiting ocean water to cool turbines take hold.

“Implementing new, more responsive resources on a system-wide scale using a market mechanism will further advance California’s clean energy goals,” said Heather Sanders, Cal-ISO’s Director of Regulator Affairs. “It could also replace or defer investments in more expensive energy infrastructure.”

Four integrated pathways are necessary to boost the state’s reliance on energy efficiency and demand response, as well as distributed generation resources like microgrids and rooftop solar without threatening reliability, according to Cal-ISO:

  • Load reshaping: Using incentives to modify consumer power use, flatten peak demand, and better forecast demand instead of building new peaking generation capacity.
  • Resource sufficiency: Ensuring enough generation resources are available to be dispatched across the system to match demand trends.
  • Operations: Changing ISO policies to use generation resources more efficiently as well as developing new market policy to better value and expand demand response participation.
  • Monitoring: Provide benchmarks and mechanisms to monitor progress and ensure the plan accomplishes its goals on time.

EV’s Help Strengthen The Grid Instead Of Crashing It

But in addition to reducing consumer power demand, Cal-ISO is also turning one of it’s biggest potential liabilities into a powerful energy storage tool – the surge of EV’s expected to hit California’s roads (and grid) over the next decade.

The Vehicle-Grid Integration Roadmap aims to coordinate EV charging with grid conditions by creating tools for EV networks to better respond to market signals like charging when demand is low and pushing power back onto the grid when demand is high.

“Vehicle electrification presents an unprecedented opportunity, through charging strategies and aggregation, to contribute to the reliable management of the power grid without impacting consumer driving habits,” reads the report…At a minimum, managed or smart charging strategies are needed to ensure EV’s do not increase peak load, requiring additional generation or capacity expansions.”

Turning EV’s from a potential grid reliability risk into a resource is an important issue for the state. It’s home to the most EV’s in America, and is targeting 1.5 million EV’s by 2025 as part of a multi-state compact. California’s also home to the most renewable energy output of any state, so ensuring EV’s integrate with the grid can alleviate concerns of “crashing” the grid when they’re all plugged in while expanding the market for renewable generation when it’s available.

Similar to the demand response/energy efficiency roadmap, Cal-ISO outlines three pathways to best integrate EV’s onto the grid:

  • Determine vehicle-grid-integration value: Determining value of grid services like energy storage and distribution to EV owners, while estimating the total market potential for VGI services.
  • Establish policies and regulations: Defining how EV’s can integrate with the wholesale and retail power markets as well as setting fair compensation for grid access to EVs.
  • Enable technology innovations: Supporting technologies to better manage EV integration like aggregation, grid-EV communication, and control over two-way power flow.

Can California Once Again Lead Us To A Clean Energy Future?

Perhaps most promising, however, is the fact that Cal-ISO isn’t just making these policy decisions in a vacuum. Both roadmaps were developed in concert with utilities, developers, and business interests to ensure they’re realistic.

And in addition to the two roadmaps, Cal-ISO recently approved a multi-year reliability planning process with the California Public Utilities Commission so the lights stay on as the state moves toward a 33% renewables by 2020 goal.

California is already the epicenter of America’s clean tech market, and it’s safe to say other states and grid operators look west when seeking best practices to reliably add clean energy resources. But the state has also been the location of one of the biggest energy market failures – Enron. By carefully assessing what’s needed to make the power system of tomorrow work, Cal-ISO may just be creating a roadmap for the rest of the U.S. to follow.

Here’s my latest monthly report of the “Top 10” most compelling non-CleanTechnica clean energy and environment-related news stories encountered last month. These articles may have an impact on your business, your life, and the world we live in. Or, at the very least, might surprise you about what’s going on.

Over a thousand articles were reviewed across various energy platforms, 30+ were found to be of particular interest and are available in my newsletter upon request. The 10 most interesting to me are shown here, most important posted last.

10. Here’s a report of renewable energy platforms for 2011 and 2012, highlighting the top wind and solar companies and the top consuming countries. In summary, renewables are entering a 5-year period of essential innovation, consolidation, and bankruptcies. Late bond payments and defaults on $8.4B in debt abound for recent Chinese leaders: Suntech, LDK, GCL, ZK and Yingli.

9. GlobalData reports that renewable energy sources will account for 20% of the global energy mix by 2030, with natural gas rapidly transitioning, but with solar thermal being the predominant renewable.

8. A study of the 6000 power plants in the US reports that the “50 dirtiest” produce 33% of US GHG emissions, but only 16% of the electricity. They account for 2% of the global GHG total and, if they were a country, would produce more than Canada, Germany, and North Korea. They are located in coal-lobbying states of Alabama, Missouri, Texas, and Georgia.

7. There’s more scientific evidence that manmade contributions to global warming are responsible for many recent extreme weather events. The report states that as GHG emissions and global temps increase, agricultural yields will decline; storm severity will worsen, producing flooding; droughts will extend; and forest fire burning acreage will increase. Germany’s Environment Minister claims humans are the primary cause of global warming.

6. New “leaked” report from climate watchdog IPCC, challenges the direct relationship between atmospheric CO2 and global temperature warming. Whereas CO2 levels have increased 1997-2012, global temps (they say) have risen at a quarter of the rate predicted in 2007, leading to a renewed debate about climate change correlations. Stay tuned, as this could be huge!

5. According to Climate Central, the current amount of climate warming CO2 in the atmosphere has already “locked in” over 4 feet of rising tides along US coastlines by 2100. This will displace over 3 million folks in over 300 communities, most notably Florida, Texas, and the East Coast.

4. Giant Honeywell, a Fortune 100 Co, introduces interface software that enables partner organizations to integrate their energy management (EMS) programs with Honeywell’s Wi-Fi thermostats. Not to be outdone, French energy giant Schneider delves into the home EMS market with its “Wiser” line of hardware and software. Both are principally for the home EMS market with adaptability to smartphones, tablets, or computer.

3. Energy management (EMS) programs that are widely adopted across Europe and the US are finally taking hold in China. Their first formal program is being piloted in industrial Dezhou City between the Dezhou Energy Conservation Center, 52 Chinese industrial companies and the Institute of Industrial Productivity (IIP) — a global company based in DC.

2. Surprisingly, the oil & gas industry accounted for 49% of all the investments in CO2 mitigation technologies 2000-2012. Of the $336B total invested, it breaks out this way: O&G invested $165B ($84B is for shale gas alone), private industry $91B, and the federal govt $79B.

THE NUMBER ONE CLEAN ENERGY ARTICLE IN SEPTEMBER

1. The largest fossil fuel company, Exxon/Mobil, admits that global warming is real, that fossil fuels are the main cause, and that society must shift to renewable power sources. Embedded chart shows progression of GHG pollution thru 2100, suggesting we have already reached the point of safe “stabilization.”

BONUS NEWS FEATURE – FOR FUN

Keep your eyes open — and nostrils closed — for developments on this discovery by researchers in Australia. The Mediterranean legume — Biserrula — when fed to livestock, is shown to reduce methane flatulence in livestock by 90%. This is important because livestock are estimated by some researchers to contribute at least 51% of the worlds’ GHG emissions.
