California Reaffirms EV Leadership

— October 13, 2014

California Governor Jerry Brown has doubled down on the Golden State’s commitment to electric vehicles (EVs) by enacting six laws aimed at promoting EVs.  The package of legislation includes two laws aimed at making EVs available to a broader audience of individuals – one for people who live in multi-unit dwellings and another with incentives for getting EVs into carshare programs.

Landlords in California now cannot block the installation of EV charging equipment through restrictive leases if renters agree to pay the costs.  This law will help California’s large renter population join the EV crowd and could help the state reach its goal of 1 million EVs on the road by 2023.  Most purchasers of EVs to date live in single-family homes, and this law removes one potential obstacle for broader adoption.

According to Navigant Research’s report, EV Geographic Forecasts, which was produced before these new laws were passed, California was likely to have approximately 820,000 light duty EVs on the road by 2023.

Smoggy and Dry

California is home to 7 of the 10 cities in the United States with the worst air quality, including smoggy Bakersfield, and has endured 3 consecutive years of drought, which is motivating Governor Brown to continue efforts to promote emissions-free driving in the state.  Some of those afflicted communities might breathe a little easier in future years, as another of the new laws targets incentives for placing EVs in carsharing programs in lower income areas with air quality problems.  EVs make sense in carshare and rental programs, as users don’t have to refuel the vehicles, and motorists who have a good experience could later become EV purchasers.  However, even after federal and state incentives, higher priced EVs are still out of reach of many consumers.

Incentives for plug-in vehicle drivers, such as HOV access, have proven critical in increasing EV adoption.  States such as California, Georgia, Oregon, and Washington that offer financial and other incentives are also the top sellers in EVs per capita.  According to HybridCars.com, sales of plug-in hybrids are up 44% over last year, while sales of battery electric vehicles are up 20%.

 

Waste-to-Energy Needs New Regulations

— September 18, 2014

A recent study published by the Earth Engineering Center (EEC) of Columbia University estimates that if the total volume of municipal solid waste (MSW) produced in the United States were incinerated in waste-to-energy (WTE) power plants, 12% of the country’s total electricity demand could be met.  This is more than 5 points higher than the current share of U.S. energy demand met by renewable sources today (7%), with WTE representing just a small fraction of the total energy mix.

Just 86 WTE plants are in operation in the United States today.  No new plants have been built since 1995.  Meanwhile, Waste Management recently divested its Wheelabrator Technologies subsidiary, which operates 17 plants around the country.

With so much upside, why does this market continue to stagnate?

Waste Pyramid

The United States currently produces 250 million tons of trash annually across the country.  This represents 15% to 20% of the global total.  Despite an abundance of feedstock, three primary barriers limit market growth: lack of regulatory support, lack of public support, and low electricity rates.

Among these, lack of regulatory support is often cited as the primary barrier to realizing the market’s full potential.  Across the United States, for example, landfilling continues to be the de facto solution for disposing of MSW, with relatively few exceptions.  On average, about 11% of the MSW is diverted to WTE and around 35% is recycled or composted.  The remainder (54%) is landfilled.  This reflects a waste management regulatory regime in the United States that falls well short of more aggressive policies set forth by European policymakers.

European principles articulated under a waste management hierarchy pyramid framework provide strong support for WTE and energy recovery.  A combination of land constraints, higher electricity prices, and a perilous dependence on Russian natural gas has provided European policymakers the motivation needed to enact strong support for WTE and other energy conversion technologies.  Combined with higher tipping fees – the cost of disposing of waste – these policies help reduce dependence on landfills.

Plenty of Fuel

By contrast, waste management in the United States is not coordinated at the federal level.  Instead, policy implementation is left to state discretion.  Individual states – Connecticut, Maine, Massachusetts, Minnesota, and New Hampshire among the leaders – have been far more aggressive in investing in infrastructure to boost recycling and energy recovery from MSW, but these policies have not yet found broad support across the rest of the country.

Recent market developments in the United States, however, signal a likely pendulum shift in favor of WTE and other waste conversion technologies.

In anticipation of tightening restrictions around coal-based generation from the U.S. Environmental Protection Agency (EPA), utilities and state policymakers are actively seeking alternative sources of energy that provide the coveted baseload capabilities of centralized fossil plants.  Among baseload renewables, WTE is among the few options logistically feasible across the country, with MSW generated in abundance and continuously in areas of high population density.

Meanwhile, according to findings in Navigant Research’s Smart Waste report, the traditional waste management market is facing a disruption similar to that faced by electric utilities at the hands of distributed generation.  Although these solutions seek to turn a liability (trash) into a strategic resource, WTE and other energy conversion technologies will benefit from greater emphasis placed on the value of waste as an input for renewable energy generation.

We expect energy recovery solutions to generate 70% of the revenue attributable to next-generation waste management technologies in North America.  While this represents a healthy growth opportunity, it’s just the tip of the iceberg, as the EEC study demonstrates.

 

Smoggy Skies Drive City Innovation

— September 16, 2014

The air pollution caused by rising vehicle numbers and coal-fired power plants in Chinese cities has been well documented.  But these issues are not limited to cities of the developing world.  In March, smog levels in Paris reached levels that forced the city government to limit vehicle access to the city and make public transportation free.  Subsequent analysis suggests that this drastic measure had a notable impact on air quality, if only temporarily.

Paris is not alone among European cities in suffering from deteriorating air quality.  London and other U.K. cities, for example, have been under the spotlight for failing to meet European Union (EU) standards on air quality.  A report in July suggested that Oxford Street in London was one of the most polluted roads in the word with regard to nitrogen dioxide (largely produced by diesel buses and cars), with levels 3 times the EU-recommended amount – and higher than Beijing.  London and some other U.K. cities are not expected to meet EU targets for air pollution reduction until 2030.

Fewer Vehicles, Cleaner Air

The World Health Organization estimates that outdoor air pollution causes 3.7 million premature deaths worldwide each year; this mortality rate is due to exposure to small particulate matter of 10 microns or less in diameter, which cause cardiovascular and respiratory diseases and cancers.  Of particular concern in cities are fine particulate matter below 2.5 microns, referred to as PM2.5, which can lodge deep within the lungs.  This life-threatening type of smog is created by burning vehicle fuel as well as other fuels such as coal and wood.

The need to address air pollution is becoming a significant driver for the adoption of electric vehicles in cities, restrictions on the worst polluting vehicles, and the introduction of technologies that can monitor and improve air quality.  Madrid, for example, is using parking fees to target the worst polluting vehicles, while also introducing an electric bike rental scheme.  Boston is piloting high-tech city benches that can collect information on air quality and provide solar-powered charging for electronic devices.  Other high-tech attempts to improve air quality have been less than successful: a project supported by the Mayor of London that used a form of glue to collect contaminants proved to be largely ineffective in capturing vehicle pollution.  More recently, the Mayor has suggested that diesel vehicles, responsible for much of London’s damaging air pollution, may face additional charges for driving in the capital under the city’s congestion charging scheme.

Looking East

In the future, western cities may look to China as a leader in air quality improvement.  In 2013, the Chinese government launched its Airborne Pollution Prevention and Control Action Plan, which will see it invest $277 billion in an attempt to reduce air pollution by up to 25% in selected provinces and cities (including the municipality of Beijing) by 2017 compared to 2012 levels.  Beijing alone is expected to invest around $160 billion.  Beijing is also working with IBM on a 10-year project called Green Horizon that will employ sensor technologies, big data analytics, weather modelling, and other advanced techniques to help the city monitor and address air pollution.  The project will also integrate renewable energy forecasting and industrial energy management.

In North America and Europe, air pollution is often associated with a previous age of industrialization, but the growing public awareness of the continuing threat to public health is accelerating policy and technology innovation.  Ultimately, air pollution in our cities needs to be addressed through a combination of transportation and energy policies and the general adoption of clean fuel vehicles and other clean technologies.

 

Winners and Losers under the U.S. EPA’s Clean Power Plan

— September 5, 2014

The most cost-effective and accessible way for states to replace retiring coal plants and comply with the U.S. EPA’s proposed carbon regulation (the Clean Power Plan, or CPP, released in June 2014) is through demand-side measures.  These include the energy efficiency programs that the EPA uses to calculate emissions rate targets in the CPP as well as other measures, such as demand response.  Analysis by Navigant and others shows that measures that cut demand growth will cut compliance costs.  However, most states cannot meet their targets by energy efficiency alone.

It’s in electricity customers’ best interest for states and utilities to implement the CPP with as much emphasis on energy efficiency and demand response as they are physically and financially able to.  For this primary reason, states and utilities will expand programs where they already exist and introduce new programs where there are gaps.

Accelerating Retirements

The costs to comply with the CPP, in addition to costs to comply with other environmental regulations as well as competition with low-cost natural gas, will drive approximately 45 GW of additional coal retirements by 2025, beyond anticipated retirements without the CPP (according to Navigant’s analysis).  The aging U.S. coal fleet already faces troubled times, with low natural gas prices expected to continue and the Mercury and Air Toxics Standards (MATS) requiring hundreds of coal plants to install costly emissions controls or shut down.  As coal plant owners look ahead to a carbon-constrained future, they are weighing complex decisions about whether it makes sense to invest in improvements in the near term when the long-term future of their coal fleets is uncertain.  Much depends on what the EPA’s final regulation will look like and how states will choose to implement it.

While the discussion around coal retirements tends to center on replacement by natural gas, wind and solar will also play a role.  The CPP will drive solar and wind generation above and beyond existing renewable targets, even in states that do not currently have a Renewable Portfolio Standard.  Growth will be particularly strong in areas that have high potential for solar and wind, such as the Desert Southwest and the Texas Panhandle, and where higher power prices make renewables more cost-effective.  Although much of the new solar capacity will be distributed customer-scale generation, wind installations will continue to be larger, utility-scale deployments.

New Questions Raised

The power sector has been expecting federal-level climate change policy or regulations for years.  This has been a major area of uncertainty for future generation planning.  However, the release of the proposed CPP has not led to any concrete assumptions for the future, and it has likely generated more uncertainty than it has quelled.  How will the EPA fashion its final regulation?  Will states choose to band together to implement the regulation, and will the basis for their implementation be rate-based or mass-based targets?  How will energy efficiency be measured and verified?  How will differences between states be reconciled in a system where electricity is constantly moving across state lines?  The answers to these questions will drive broad changes in the power sector and have ripple effects across the national economy.  These ripples will be felt by all industry players that are electricity customers (i.e., everyone) and, indirectly, by the healthcare industry (handling fewer conditions brought on by poor air quality) and the insurance industry (facing lessened impacts of climate change).

It’s not surprising that the CPP will transform the domestic power generation landscape, reducing coal use, lowering demand growth (due to energy efficiency and conservation programs), and increasing gas-fired and renewable generation.  Thinking globally, the plan could be just what the international community has been calling for: leadership on climate change from the United States that will push other nations (notably China and India) to follow suit.
