合同能源管理模式 Energy Performance Contracting (EPC)
我公司按國際通用的合同能源管理模式進行業務運作，合同能源管理是一種新型的市場化節能機制，其實質是以減少的能源費用來支付節能項目全部成本的節能業務方式。
SANCHUAN operates according to international energy performance contracting mode. EPC is a new market-oriented energy-saving mechanism. Its essence is to use the stream of income from the cost savings to repay the costs of the energy saving project.
EPC 模式帶給能耗企業的效益 Benefits From Epc Mode
零投資：企業不僅可以免費獲得設備升級的機會，而且合同期滿后，將無償獲得全部技改設備，加速完成企業的節能指標。
零風險：節能改造施工過程中，在保持原有的工況條件下，只更換設備，不改變原有管網和安裝基礎，改造作業只局限在設備房內進行，對備用設備進行改造，改造完成后切換為運行設備，對正常生產、運營不產生任何影響。
高收益：節電效率高，節電率一般可達 18%——38%，大大降低了生產成本。
提升競爭力：客戶實施節能改造后，減少了用能成本支出，提高了產品競爭力，改善了環境品質，建立了綠色企業形象，增強市場競爭優勢。
Zero investment: Company can not only get the opportunity to upgrade equipments, but after the contract expires, will be free to get all the technological equipments, accelerating the completion of energy-saving targets of enterprise.
Zero risk: During energy-saving construction process, maintaining the original working conditions, SANCHUAN only replaces equipments without changing the original pipe network and the installation base. And the transformation operations are confined to the equipment room, transforming the spare equipments. After finishing transformation, reformed equipments are switched to run. There is no effect on the normal production and operation.
High Benefits: high energy efficiency, energy-saving rate is generally up to 18% - 38%, greatly reducing the cost of production. Enhance competitiveness: After energy efficiency transformation, client reduces energy costs, improves product competitiveness and the environmental quality, establishes green corporate image and enhances market competitiveness.
基本模式 Basic Mode
1. 節能效益分享型 Shared Savings
節能改造工程前期投入由我公司支付，合同期內按照一定的比例與客戶分享由節能改造帶來的降耗收益。合同期滿，節能設備及長期收益全部歸客戶所有。
SANCHUAN is in charge of upfront investment of energy efficiency transformation. According to a certain percentage stipulated by the contract, SANCHUAN shares customers with benefits from the energy-saving. When contract expires, customer owns energy-saving equipment and long-term energy-saving gains.
2. 節能效益支付型 Project Procurement
客戶委托節能服務公司進行節能改造工程，先支付一定比例的預付款，余額用節能效益支付。
Client entrusts SANCHUAN to conduct energy saving projects and pays a certain percentage advance payment. The balance of payments will be paid by energy efficiency benefits.
3. 能源費用長期托管型 Chauffage
在保證客戶能源成本降低的前提下，客戶能源費用全部交由節能服務公司管理。節能設備長期的運行管理維護、更新改造再投入均由節能服務公司承擔。
On the premise of ensuring customer energy costs to reduce, SANCHUAN manages customer energy costs. Long-term maintenance、update and reinvestment of energy-saving equipment are all assumed by SANCHUAN.
4. 節能量保證型 Guaranteed Savings
江西三川節能股份有限公司擁有一流的節能技術、維護專業團隊，可根據業主需要對節能改造項目實行買斷模式，即根據年節電量，雙方約定按一定金額一次性支付節電收益的業務模式。
SANCHUAN has a professional team with first-class energy-saving technology. Buyout mode is available for energy efficiency transformation projects as per owner’s need. Namely, based on annual saved electricity, two parties agree to do one-off payment for energy saving benefits.
節電收益計算 Quantifying Energy Saving Benefits
通過智能化手段實現現場勘查，完成數據采集，根據以下方法計算節能技改節電量：
1.節電率 =(W 原泵 -W 節能泵 )/ W 原泵 ×100%
2.總年節電 =(W 原泵 -W 節能泵 ) × 年運行時間 ( 小時 ) × 設備數量
3.年節電效益 = 總年節電 × 電價
W 原泵—改造前運行功率
W 節能泵—改造后運行功率
Intelligent method is used for site survey and data acquisition. According to the following means, reduced electricity cost can be calculated:
1.Energy saving rate=(Woriginal pump–Wenergy efficiency pump)/ Woriginal pump×100%
2.Total annual saving =(Woriginal pump–Wenergy efficiency pump)×annual operation time (hour) ×equipment quantity
3.Annual saving benefits= total annual saving×electricity price
W original pump—operating power before transformation
W energy efficiency pump—operating power after transformation
節能效益分享方式 Sharing Mode
在全年運行 345 天的基礎上，節能改造后產生的效益按 0.65 元 /kw·h、分享六年為標準，按月支付，分享比例如下（具體按雙方簽署的《節能技術改造合同》執行）：
On the basis of a year with 345 days, saving benefits are calculated at 0.65yuan/kw·h, 6-year sharing, monthly payment, sharing proportion is as follow (subject to signed Energy Efficiency Transformation Contract)
注：年運行時間和電價發生變化時，分享比例與年限也作相應變化
Attention:If annual operating time and electrovalence had change,the proportion of share and working seniority will also be different.
計算案例 Case
原有參數 Original Parameters
更換三川水泵參數 Parameters from SanChuan pump
理論收益計算：
水泵電功率可根據公式 W=UIcosΦ 3 計算，也可以直接用儀表測量得出。案例中，改造前老泵運行電耗為每小時 423kw.h( 實測 ), 更換三川節能泵以后耗電量為每小時 336kw.h，該系統全年按 8000 小時 計 算， 每 年 節 電 量：（423-336）X8000=696000kw.h, 電 費 按 0.6 元 / 度， 則 全 年 節 約 電 費 支 出：696000X0.6=417600 元
Theoretical calculation income:
The electric power of water pump can be calculated according to the formula w = uicos Φ 3, or it can be directly measured by instrument. In the case, before the transformation, the power consumption of the old pump was 423kw. H per hour (measured), and after the replacement of Sanchuan energy-saving pump, the power consumption was 336kw. H per hour. The annual power consumption of the system is 8000 hours, and the annual power saving: (423-336) x8000 = 696000kw. H, and the power consumption is 0.6 yuan / kWh, so the annual power saving expenditure is 696000x0.6 = 417600 yuan.
