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(yè)務運作，合同能源管理是一種新型的市場化節(jié)能機制，其實質(zhì)是以減少的能源費用來支付節(jié)能項目全部成本的節(jié)能業(yè)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(yè)的效益 Benefits From Epc Mode
零投資：企業(yè)不僅可以免費獲得設(shè)備升級的機會，而且合同期滿后，將無償獲得全部技改設(shè)備，加速完成企業(yè)的節(jié)能指標。
零風險：節(jié)能改造施工過程中，在保持原有的工況條件下，只更換設(shè)備，不改變原有管網(wǎng)和安裝基礎(chǔ)，改造作業(yè)只局限在設(shè)備房內(nèi)進行，對備用設(shè)備進行改造，改造完成后切換為運行設(shè)備，對正常生產(chǎn)、運營不產(chǎn)生任何影響。
高收益：節(jié)電效率高，節(jié)電率一般可達 18%——38%，大大降低了生產(chǎn)成本。
提升競爭力：客戶實施節(jié)能改造后，減少了用能成本支出，提高了產(chǎn)品競爭力，改善了環(huán)境品質(zhì)，建立了綠色企業(yè)形象，增強市場競爭優(yōu)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(jié)能效益分享型 Shared Savings
節(jié)能改造工程前期投入由我公司支付，合同期內(nèi)按照一定的比例與客戶分享由節(jié)能改造帶來的降耗收益。合同期滿，節(jié)能設(shè)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(jié)能效益支付型 Project Procurement
客戶委托節(jié)能服務公司進行節(jié)能改造工程，先支付一定比例的預付款，余額用節(jié)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(jié)能服務公司管理。節(jié)能設(shè)備長期的運行管理維護、更新改造再投入均由節(jié)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(jié)能量保證型 Guaranteed Savings
江西三川節(jié)能股份有限公司擁有一流的節(jié)能技術(shù)、維護專業(yè)團隊，可根據(jù)業(yè)主需要對節(jié)能改造項目實行買斷模式，即根據(jù)年節(jié)電量，雙方約定按一定金額一次性支付節(jié)電收益的業(yè)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(jié)電收益計算 Quantifying Energy Saving Benefits
通過智能化手段實現(xiàn)現(xiàn)場勘查，完成數(shù)據(jù)采集，根據(jù)以下方法計算節(jié)能技改節(jié)電量：
1.節(jié)電率 =(W 原泵 -W 節(jié)能泵 )/ W 原泵 ×100%
2.總年節(jié)電 =(W 原泵 -W 節(jié)能泵 ) × 年運行時間 ( 小時 ) × 設(shè)備數(shù)量
3.年節(jié)電效益 = 總年節(jié)電 × 電價
W 原泵—改造前運行功率
W 節(jié)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(jié)能效益分享方式 Sharing Mode
在全年運行 345 天的基礎(chǔ)上，節(jié)能改造后產(chǎn)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(jié)能技術(shù)改造合同》執(zhí)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(fā)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(shù) Original Parameters
更換三川水泵參數(shù) Parameters from SanChuan pump
理論收益計算：
水泵電功率可根據(jù)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(jié)能泵以后耗電量為每小時 336kw.h，該系統(tǒng)全年按 8000 小時 計 算， 每 年 節(jié) 電 量：（423-336）X8000=696000kw.h, 電 費 按 0.6 元 / 度， 則 全 年 節(jié) 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.
