| * Coefficient of Utilization (COU) - Is a factor used to determine the efficiency of a luminaire in delivering light for a specific application. ** Useful Lumens - If at least 80% of the total light output (luminous flux) from a luminaire is in a cone of pi steradians (120°), that is considered to be Useful Lumens. What matters is not the total light output (luminous flux) but where the light is shining. The more light that is thrown forwards into the 120° cone, the better. Light emitted outside of this cone is generally considered to be wasted *** % of Energy Savings - the savings % achieved by Samudra LED luminaires do not compromise on the existing lux of the conventional lights which have been compared. Infact along with the projected savings, lux improves by ~ > 50%. Higher savings can be achieved by using Samudra's auto-dimming feature. |

| COMPARISON OF ESCO MODELS FOR LED STREET LIGHTING PROJECTS_SAMUDRA LED Vs COMPETITION | ||||
| Sr. No. | Description | SAMUDRA | COMPETITION | Remarks/Observations |
| 1 | Nature of contract | Energy Performance Contract | Annuity Model | SAMUDRA: No capital expenditure required. Contract based on Performance and Sharing of Energy Revenue. Project entitled to earn Carbon Credits as Savings can be proved. Penalties on SAMUDRA in case of non-performance. Project drives Accountability and Smart Governance. COMPETITION: Savings are not based on facts but on deemed (assumed) savings. Cost of project is based on EMI model. No penatly clause for non-performance. Since no baseline, project not eligible for carbon credits. High risk project for the Municipality. |
| 2 | Lumen Depriciation | ~10% over 10 yrs. | ~30% over 7 yrs. | SAMUDRA: System Efficacy ranges between 110 to 130 Lm/W. High Efficacy and Low Lumens Depriciation means over 10 years the System Efficacy will come down to 99 to 117 Lm/W. COMPETITION: System Efficacy ranges between 80 to 90 Lm/W. Low Efficacy and High Lumens Depricition means over just 7 years, the System Efficacy will drasticaly come down to 56 to 63 Lm/W. This means the illumination levels/lux will reduce by a very large margin. |
| Baseline Audit by an Independent Engineer | Yes | No | SAMUDRA: Baseline Audit is carried out by and Independent Engineer before implemetation of the project. This ensures accountibility, transparencey and creates a benchmark for calculating energy savings acheived after installing LED Lights. COMPETITION: Energy savings are most of the times based on deemed savings without any baseline audit conducted. Even if the baseline audit is conducted it is generally conducted by the vendor company itself. This compromises on transparency and accountability. |
|
| 3 | Assurance to Govt. of minimum committed energy savings. | Yes | No | SAMUDRA: Assurance of minimum committed energy savings which can be measured using CCMS - remote centrally controlled monitoring system. COMPETITION: Only 50% deemed savings. No provision to verify and prove energy savings. |
| 4 | Government's earnings though energy savings | Yes | No | SAMUDRA: Govt. earns an agreed percentage/share from achieved savings based on Baseline Consumption COMPETITION: Govt. earns nothing. |
| 5 | Payment Structure | Based on actual, achieved and committed energy savings | Annuity schemed based on deemed energy savings | SAMUDRA: gets its monthly payment only after achieving and proving minimum committed energy savings. COMPETITION: Get fixed monthly instalments based on deemed savings. No provision to verify and prove energy savings and lamp performance. |
| 6 | Payments by Govt. to Vendor | Yes | No | SAMUDRA: Samudra will receive payment based on actual savings with reference to base line & Factual Data . COMPETITION: will receive PAYMENT based on DEEMED SAVINGS with reference to DEEMED BASELINE and DEEMED ENERGY BILLS |
| 7 | Penalty Clause on non-achievement of committed energy savings | Yes | No | SAMUDRA: Severe penalties if assured minimum committed savings are not achieved with respect to baseline. COMPETITION: No reference point created in form of baseline and hence energy savings cannot be proved. So, no Penalty Clause. |
| 8 | Turn around Time to repair faults in lighting | 24 hrs. | 48 hrs. | SAMUDRA: has a system to detect faults thereby ensuring they are repaired in 24 hrs. Accountability in Public Lighting System is created for the first time in India. COMPETITION: No process/system to monitor faults. Repairs addressed in 48 hrs. after receiving consumer complaints. |
| 9 | Power Theft Monitoring | Yes | No | SAMUDRA: CCMS has the ability to detect power loss/abnormalities in power consumption. COMPETITION: No such provision. |
| 10 | Auto On/Off Feature for Direct Point Street Lights. | Yes | No | SAMUDRA: Photocell feature for direct point street lights. This eliminates the need of manual intervention to operate the lights and optimizes energy savings. COMPETITION: NA. |
| 11 | Disaster Management | Yes | No | SAMUDRA: a provision to switch off all the lights in a single command from a remote location in case of an eventuality. COMPETITION: No such provision. |
| 12 | Mechanism to establish baseline for energy consumption of existing street lights | Yes | No | SAMUDRA: Independent Energy Auditor (IEA) appointed to establish existing power consumption at each feeder point. COMPETITION: No such provision. Project based on deemed savings. |
| 13 | Mechanism to establish baseline for Lux of existing street lights | Yes | No | SAMUDRA: Independent External Auditor appointed to establish existing Lux at each feeder point. COMPETITION: No such provision. |
| 14 | Mechanism for Asset Marking | Yes | No | SAMUDRA: Independent External Auditor appointed for this purpose. COMPETITION: No such provision. |
| 15 | Acknowledgement of Baseline Data by Authorized Designated Body as per the EPC | Yes | No | SAMUDRA: Joint Survey Team to acknowledge the baseline findings conducted by the IEA. The ECM Plan of SAMUDRA needs approval of IEA based on which Ammendment Agreement is executed between Govt. and SAMUDRA for every Phase. The ECM can be executed by SAMUDRA only after the amendment Agreement. This procedure eliminates all future disputes with respect to the project. COMPETITION: No provision for baseline survey and any such procedures. |
| 16 | Co-relation of energy bills with energy consumption | Yes | No | SAMUDRA: Bills generated on actual, measured, proved energy consumption. COMPETITION: Bills generated on assumed energy savings which are based on the earlier generated bills, which were also based on deemed consumption. Deemed savings based on deemed consumption leads to inaccurate and misleading figures. |
| 17 | Performance Monitoring System | Yes | No | SAMUDRA: Has specially designed a transparent software based system called CCMS (Centralized Control Monitoring System) which will monitor light performance and their electrical parameters, record power consumption and savings and generate reports and bills. COMPETITION: No such system. |
| 18 | Provision of Audit by IEA to ensure committed performance | Yes | No | SAMUDRA: Periodical audits by IEA to certify performance. COMPETITION: No such provision. |
| 19 | Call Centre Provision for Monitoring Performance and attending to service calls | Yes | No | SAMUDRA: Dedicated call centre to monitor performance 24x7 using CCMS. COMPETITION: No provision for monitoring performance. |
| 20 | Performance Related SMS Alerts | Yes | No | SAMUDRA: JMC and designated personnel will receive alerts via SMS for any abnormalities. COMPETITION: No such provision. |
