In March, 2013, Binhai Branch of Tianjin Electric Power Corporation officially accepted an application for distributed power grid integration from resident Dong Qiang. This is the first application for resident-generated power grid integration accepted in Tianjin and it is expected to be promoted across China. Kyo’ce’ra, a member of Bayer China’s EcoCommercial Building (ECB) network, leveraged its photovoltaic power system to this first power grid user in Tianjin with a comprehensive solution.
Bayer ECB EcoCommerical Building program Kyocera Provides System Integration Resident-Generated Power Grid Tianjin
Recently, Kyocera joined the EcoCommercial Building (ECB) program China network. As a photovoltaic applications producer and system integrator, Kyocera can bring its expertise in the renewable energy field to this partnership. The partnership gives the ECB program an opportunity to develop multidisciplinary system solutions in collaboration with network members that lead their respective industries.
In March, 2013, Binhai Branch of Tianjin Electric Power Corporation officially accepted an application for distributed power grid integration from resident Dong Qiang. This is the first application for resident-generated power grid integration accepted in Tianjin and it is expected to be promoted across China. The Kyo’ce’ra photovoltaic power system provides this first power grid user in Tianjin with a comprehensive solution including solar panels, inverters, stands and construction & installation instructions. This enables the resident not only to “generate power by oneself, use power by oneself”, but also to implement solar power integration at his or her own will, thereby actively engaging in addressing the energy and environment issue.
Dong’s family of five live in a morethan200sqm, three-storey townhouse at Tanggu EuroChic Town, Binhai New Area. Their electricity usage surpasses 400 kWh and they used to pay RMB300 per month which is calculated based on three-level electric prices. Now, this new system configuration, with an investment of RMB40, 000, generates 15 kWh electricity each day, said Mr. Dong. If electricity has any redundancy at home, it is very worthwhile to sell surplus power to the grid company.
Mr. Dong also calculated that the system can generate 600 kWh of electricity per month once in operation and the extra power generated can be sold to the grid. Under a tiered electricity pricing mechanism, approximately RMB 474 can be saved each month, calculated on the tier-3 electricity price of RMB0.79/kWh. In other words, energy expenditures of RMB5688 can be saved and the investment cost can be recovered in 11.5 years, while the photovoltaic power generator has a useful life of at least 20 years. If an appropriate subsidy is granted in the future, the time of cost recovery will be even shorter.
In fact, relevant national policies are also expected to be implemented soon in China. In the Twelfth Five-Year period (2011-2015), national policies have clearly been in favor of environmental protection and carbon emissions trading system has also been put in the agenda. The National Energy Administration (NEA) officially issued the Twelfth Five-Year Plan for Solar Power Generation on September 12, 2012, clearly stating that developing distributed photovoltaic (PV) power generation is an important field of domestic PV applications. They also urged local governments, grid operators and power generation enterprises to actively implement the plan via related supporting policies. Backed with the pioneering spirit, Mr. Dong has been at the forefront of distributed power generation in China.
With a relatively strong awareness of environmental protection, he knows that developing distributed PV power generation not only is about obtaining an economic benefit, but also about being conscious of a far-reaching environmental implication. “Saving 1 kWh electricity means reducing 1kg of carbon dioxide. Therefore, 2,800 kg of standard coal can be saved in one year, 7,178 kg of carbon dioxide can be reduced, and 1,958 kg of carbon-containing dust can be reduced,” he said, “as a result, PM2.5 emissions are also reduced. This is more meaningful than merely focusing on the money spent and saved.”
Nowadays, many power grid operators have officially begun to accept resident-generated power grid integration in China. With the promotion of smart power grid nationwide, individual-generated power integration is expected to be implanted in more regions.
