Cecilia cheung Edison Chen, md proposal for energy storage systems to create new value stream

Editor's note: recently, the photovoltaic (pv) grid, according to foreign media reports, Maryland proposal for energy storage systems to create new value stream, energy storage system can store electricity generated by renewable energy, and then discharge in renewable energy power generation is less, so as to reduce greenhouse gas emissions.

according to foreign media reports, some public utilities companies and government stakeholders in the public service commission (Maryland PSC） Filing, the committee should create new value stream for the energy storage system, the value stream will be according to their ability to reduce emissions and delay is compensated for upgrading demand factors such as the distribution network.

the overview of compensation method in several commercial mode can be determined ( Including all utilities, third party all or & other; Virtual power plant & throughout; Mode) Will the state's energy storage system how to monetise, in this mode the customer has the summary of energy storage projects together.

how to estimate the energy storage system of the value of the ideas from Maryland public service commission ( PSC） Energy storage members of the working group, whose members include subsidiary Exelon, Exelon, Baltimore Gas&Electric, Pepco company, the American association of energy storage, and electricity wholesale market operators PJM interconnection representative of the company.

the energy storage system is an example of value stream & other To reduce carbon emissions quantity & throughout; 。 Energy storage system can be stored by the renewable energy ( Such as wind and solar energy) The energy generated, and then at the time of renewable energy power generation is less discharge, thereby reducing greenhouse gas emissions.

according to the advice of the energy storage group, solar power, energy storage project can be release of electrical energy conversion into tons of carbon dioxide, and then the number multiplied by the price of carbon tax can calculate the value to reduce greenhouse gas emissions. And when will the value of the energy storage system together with other potential value stream, its value will be much higher than the value of using electricity prices.

the file mentioned, solar power grid, the potential energy storage projects allowed by the emissions reductions can help the greenhouse gas emissions by 2030, Maryland's target of 40% less than in 2006.

the energy storage association, national policy director Nitzan Goldberger said that Maryland is the third for the costs and benefits of energy storage system was the substantial analysis of the state.

she said: & other; At present, only California and New York for implementing revenue cost analysis framework, rather than simply to estimate the power line or power investment the extension or replacement value. If not most of the existing reform benefit cost analysis framework, regulatory and market reform at the same time, in order to promote that can provide a wide range of applications from the same assets business model, solar energy and its economic impact analysis cannot explain storage full value. ”

working group's vision of a another value stream is the deployment of energy storage system delay or cancel the transmission and distribution cost savings when the system upgrade. If more storage power, can reduce the electric power line and substation construction, so as to improve the reliability of the power grid.

according to the working group, at times of peak demand, more energy saving measures also should be viewed as the energy storage system is a kind of value stream.

the document said: & other; In electricity demand peak energy storage system meet the demand of the overall power supply, electricity utilities will reduce the overall demand for electric power system services for taxpayers to save money. ”

the team also suggested, utilities and regulators should also consider & other; Not quantitative & throughout; Value stream energy storage system. Battery energy storage project, for example, can serve as extra charging stations, which helps to promote the popularization of electric vehicle application.

in addition, due to the energy storage system pilot program will be used in a variety of ownership model, so another qualitative value stream is to develop strong energy storage supplier market, for customers in Maryland and deployment of a variety of energy storage technology.

Maryland pilot scheme of energy storage system is in the state in 2017 for residential, commercial and industrial energy storage facilities after the implementation of the investment tax credit policy.

Goldberger said, solar portal, Maryland AES company is the biggest energy storage project of an installed capacity of 10 mw Warrior Run Advancion energy storage project, which project will be opened to traffic in 2022.
