Description
Technical field
The present invention relates to a kind of photovoltaic plant increment life insurance structure and its increment life insurance method, belong to photovoltaic generation unit neck
Domain.
Background technology
《Photo-voltaic power generation station engineering project Control index》The scope of application：Newly-built, reconstruction and the ground photovoltaic hair of enlarging
Power plant project.Examine photo-voltaic power generation station engineering project land used, should according to this land use index determine total land scale and
Each function division land scale is appraised and decided, and the project of super scale land used is needed really, should carry out construction project save land evaluation establishment
Photo-voltaic power generation station engineering project feasibility study report, the total size that should be determined according to this land use index and each function division
Scale carries out scale and appraised and decided.And the special piece explanation of situation progress is appraised and decided to land scale in report.The grant land use right of photovoltaic plant
It is increasingly stricter, save the area（The particularly smooth landform resource of high-quality）Have become the principal element of photovoltaic plant construction.
National Development and Reform Commission changes price on improving the notice hair of land photovoltaic generation online stake electrovalence policy
[2015] No. 3044, photovoltaic generation first determines stake electrovalence in 2016.
Adjusted in the National Development and Reform Commission that 2015.12.24 is issued adjusts land photovoltaic generation online stake electrovalence policy
It is whole：To photovoltaic generation stake electrovalence, a class, two class resource-areas reduce by 10 points of, 7 points of, three class resource-areas drop respectively within 2016
Low 2 points of.National Development and Reform Committee announce the class Resources Area of photovoltaic rate for incorporation into the power network opinion original text three in 2017 be adjusted downward to 0.75 yuan, 0.65
Member, 0.55 yuan.The distributed photovoltaic power generation project built using building roof and attached place, can be selected when project is put on record
Select a kind of pattern in " generating power for their own use, remaining electricity is surfed the Net " or " online in full ".Distribution to " generating power for their own use, remaining electricity is surfed the Net " pattern
Formula photovoltaic generation carries out the pattern subsidized according to full electricity, and subsidy standard is respectively：The one 0.2 yuan/kilowatt hour in class resource-area, two classes
0.25 yuan/the kilowatt hour in resource-area, the three 0.3 yuan/kilowatt hours in class resource-area, above-mentioned subsidy fund pass through Renewable Energy Development fund
Paid, turned to pay by power grid enterprises；Wherein, the electricity of the personal online of having a surplus of distributed photovoltaic power generation system, by power grid enterprises
Purchased according to local coal unit mark post rate for incorporation into the power network." online in full " pattern performs photovoltaic plant price, and specific subsidy is provided
Examination and approval procedures are performed in the way of photovoltaic plant.The coefficient of the recovery initial investment of the unit quantity of electricity of photovoltaic plant diminishes, gold
Melt risk increase, it is necessary to which inside deep-cuts generating potentiality and reduces power consumption inside photovoltaic plant, increment life insurance balances external financial ring
Border changes, and realizes cost of being recouped the investment on schedule in report of feasibility.
At present, about 0.4 yuan of Chinese tradition thermoelectricity cost of electricity-generating/degree, and photovoltaic generation cost reaches 0.8-0.9 members/degree,
It there is huge price difference.By curve map, it is expected that the year two thousand twenty reaches electricity consumption side par, Generation Side par is reached within 2025.It is expected that
Photovoltaic generation country no longer subsidizes within 2025.Passage, technological progress over time, the cost curve of photovoltaic generation is constantly descending,
And the cost curve that traditional energy generates electricity can be constantly up.Both joints are exactly site in the par of photovoltaic generation.Once
Realize that par is surfed the Net, it is meant that photovoltaic enterprise need not rely on subsidy and can be got a profit.At that time, have cost advantage concurrently and environmental protection is imitated
The photovoltaic industry of benefit also really will welcome industry grand banquet.This planning is built upon on the basis of photovoltaic generation technical progress of industry
