Okay, let’s break down the key takeaways from this document regarding electricity billing for “nearby consumption โคprojects” (likely referring to on-site generation and consumption, likeโ solar or windโค power directly usedโฃ at a facility). Here’s a summary, categorized for clarity:
1.โฃ Capacity (Demand) Electricity Bill – The core Change
* โค New Calculation: The primary shift is how โข capacity charges are calculated.Insteadโ of theโฃ conventional two-part transmission andโ distribution price model, there’s a new formula:
* Capacity Bill =โ Policy-based Capacity Charge + โค(Voltage โLevel โPrice * Average Load โRate * 730 hours โฃ* Grid Connectionโ Capacity)
* Key Components of the New Formula:
* policy-Based Capacity Charge: This is determined by current regulations.
โข * โค Voltage Level Price: โฃTheโค standard electricity price for the voltage level of โฃthe connection.
โข โ *โ Average Load Rate: this is โฃa crucial factor, currently set at the โaverage for industrial/commercial users with 110kV+โ connections. It’s calculatedโ by the grid operator and โฃapproved by provincial authorities. This isโ a key variable โimpacting the cost.
* 730 Hours: A fixed โnumber of hours used in theโข calculation (likely representing peak demand hours).
* โฃ Grid Connection Capacity: Theโ total capacity connected to the publicโฃ grid, including:
โฃ * โPower receiving transformers
* High-voltage motors not connectedโ through transformers.
* โฃ Optionโค to Stay with Old Model: Projects needing high reliability and backup capacity can opt to continue with the traditional two-part transmission and distribution pricing.
2. System Operation Fee
* initial Approach: Initially,โข the system operation fee willโ be based on theโข grid power used.
* โ Transition: The plan is to move to a โfee based on capacity occupied (how muchโข capacity the project reserves on the grid).
* Self-Consumption Incentives: There’s a temporaryโค exemption of cross-subsidiesโ for self-consumedโ electricity (electricity generated and used on-site). New cross-subsidies for โself-consumption will be introduced.
3. โขPower Market Participation
* equal footing: Theโ project is treated as equal โto other power generators and users.
* โค Market-Basedโ Pricing:
โ โข*โ Spot Market areas: Trading and settlement will follow market rules.
* โ Non-Spot Market Areas: Reverse power transmission (selling excess power back to the grid)โ is generally โข not allowed.
* new Energy โขPrice Exclusion: The project’s grid power supply is not included in price settlement mechanisms designed for the โsustainable development of new energy.
* Direct market participation: The project must directly participate in market transactions when consumingโข electricity. The grid company cannot act as an intermediary.
* Wire Loss Costs: The project bears the cost of wire losses (energy lost during transmission) โฃwhen using the grid.
4. Implementation & Oversight
* โ Provincial responsibility: โProvincial priceโ authorities are responsible for tracking,โ monitoring, and providing feedback on the implementation.
* Policy Guidance: They must also interpret theโข policy and guide project owners.
* Grid Connection Process:
โ *โฃ Project owners file with local authorities.
* They apply toโ the โgrid company for connection.
* Theyโฃ independently determine grid capacity.
* They โsign contracts (power supply, purchase, grid connection) with the grid company.
* โค Grid Company audits: Grid companies must audit connections and provide settlement services based on filed documents.
* โค Reporting: โคGrid companies must report monthly data on fees to โฃprovincial authorities.
5.Effective date
* Octoberโฃ 1, 2025: This โis when the โnew rules take effect.
* Existing Projects: Local priceโ authorities will handle the transition โขfor projects already connected โbefore this date.
In essence,this document outlines a move towardsโข a more market-oriented and โtransparent electricity billing system for nearby consumption projects,with a greater emphasis on capacity charges and direct market participation. โ The average load rate and grid connection capacity willโฃ be key factors in determiningโ costs.
Do you have any specific questions about any of these points, or would you like me to elaborate on a particularโค aspect?โ For example, are you interested โin how the average โคloadโ rate is calculated, orโ the implications of not being able to sell excess power back to โคthe grid in non-spot market areas?
