From a baby accumulating of fishing villages 40 years ago to a burghal on clue for a all-around milestone, Shenzhen has appear further, faster than best cities. Already home to the better agile of electric buses in the apple – almost 14,500 at the end of May – the burghal is accepted to amaze 100 percent of its accessible alteration bus agile by the end of 2017. If successful, it will become the aboriginal in the apple to do so.
Battery-powered electric buses can accommodate ecology and bloom benefits, such as aught tailpipe emissions, activity savings, beneath babble and beneath greenhouse gas emissions. Besides allowance ample cities disturbing with poor air quality, this blazon of technology can abate ammunition costs, advance activity security,widespread acceptance in cities about the world.
Members of the all-around WRI Ross Center agent ability team, facilitated by WRI China, afresh visited the Shenzhen Bus Group, one of Shenzhen’s three above bus operators with about electric 5,700 buses, to apprentice about their acquaintance transitioning from agent and adapting to new technologies.

Despite its promise, abounding burghal bus operators about the apple accept run into barriers adopting and operating electric buses. There is generally affair about aerial basic costs, ambiguity about array performance, and a abridgement of incentives from bounded and civic governments.
Shenzhen began adopting electric buses in 2009, beneath a civic electric agent affirmation affairs that challenged 10 cities beyond China to arrange at atomic 1,000 electric cartage anniversary year for three years. Since then, the burghal has appear assorted behavior and targets acknowledging the industry and brought added electric buses into its own fleet.
To allay aerial basic costs and added abeyant risks, Shenzhen adopted several altered business models. The burghal experimented with altered leasing mechanisms for cartage and batteries to abstain abiding lock-in, and it broadcast operational risks amid stakeholders – amid bus operators, bus manufacturers, annual companies and added annual providers. For example, electric bus manufacturers are currently amenable for advancement batteries and auctioning old agent buses, as against to the operators.

Aside from banking risks, array ambit and charging issues are accepted concerns. Sometimes batteries don’t abutment a abounding avenue per charge, which reduces operational ability and increases costs. Shenzhen Bus Group’s band-aid was charging amid disciplinarian shifts, which usually booty 30 minutes, and charging brief at depots, which usually takes about two hours. Also, if there are charging accessories at the antecedent and final stops of assertive routes, managers told us no added charging time is bare to advance approved service.
To added advance efficiency, Shenzhen Bus Group developed an “octopus” charging base that can affix to four buses at a time. Though the archetypal doesn’t abutment accompanying charging, the buses don’t charge to action about the charger, extenuative time and abbreviation the charge for added charging stations.

The Shenzhen Bus Group annex we visited can abode about 20 buses at the aforementioned time. They are anchored beneath overhangs able with solar panels and aggregate charging facilities. While the solar panels accommodate electricity to ability annex lighting, there isn’t absolutely abundant accommodation to recharge buses, a ambition that will crave added innovation. In Marrakech, a GEF and UNDP accurate one megawatt solar acreage contributes to charging a baby cardinal of cartage in the city’s bus accelerated alteration fleet, but the bulk of solar panels bare per bus makes ascent difficult currently .

Shenzhen Bus Group additionally operates electric taxis and added bartering vehicles, as allotment of the city’s plan to advance air quality. These projects accommodate added curve of revenue, enabling the aggregation to aggrandize and enhance its electric fleet.
Beyond abbreviation air pollution, Shenzhen’s buses are a acute allotment of the city’s – and the nation’s – efforts to abate carbon emissions. China’s Nationally Determined Contributions to the Paris Agreement accent accessible carriage and animate the development and acceptance of new activity vehicles. The accessible alteration buses in Shenzhen annual for alone 0.5 percent of the city’s agent stock, but , according to the Carriage Commission of Shenzhen Municipality.
Despite the actuality that atramentous ability plants still annual for 66 percent of electricity bearing in China, bounded advisers appraisal Shenzhen’s electric buses can abate 48 percent of CO2 emissions, compared to agent buses, and up to 100 percent of added bounded pollutants. Gains could be alike greater with a altered activity mix.

In accession to ecology benefits, the Shenzhen Bus Group appear banking benefits, including ammunition amount savings, beneath maintenance, and bargain or no overhaul. Operators said they accepted activity costs to access due to the uncertainties of the technology and abrupt breakdowns, but these costs accept yet to materialize. One electric bus can alter 0.95 agent buses, according to their estimates, with operating accumulation compensating for college antecedent basic and banking costs.
Shenzhen’s acquaintance is a archetypal for others. The burghal managed to innovate in procurement, operation and maintenance, all affected central broader civic and bounded behavior and targets. It’s a able archetype of assorted burghal stakeholders accelerating the acceptance of cleaner technologies in the carriage sector.
Shenzhen is acceptable to be the aboriginal burghal to canyon the 100 percent electrification anniversary – but it won’t be the last.
We would like to abnormally acknowledge the WRI China aggregation for their efforts alignment this visit.
