Smart Power India launches its Technical Monitoring Guide for Solar Hybrid Mini-grids in India
New Delhi: Smart Power India, a subsidiary of Rockefeller Foundation, today launched its Technical Monitoring Guide for Solar Hybrid Mini-grids in India. The past decade has witnessed great interest in mini-grids as a potentially transformative solution to last-mile energy access in the developing world. Mini-grid operating models and technologies continue to evolve with a dynamic customer base. The Guide seeks to provide standard protocols for measuring, analyzing, and interpreting the performance of mini-grid plants and their key components.
Commenting on the report launch, Jaideep Mukherji, CEO, Smart Power India, said, “Mini-grid developers in India, Africa, and around the world have led the way in establishing new business models, deploying innovative technologies, and securing government recognition and support. Yet mini-grids continue to operate in remote locations under challenging conditions which put immense strain on plant electronics, batteries, and other equipment. This leads to accelerated degradation which in practice often goes unnoticed and unmitigated.” Mini-grids operate in challenging environments, and their viability depends largely upon building and maintaining integrated and efficient technical systems. Due to lack of resources, low availability of appropriate equipment, and inadequate technical support services, projects frequently struggle to realize their full potential. Robust evaluation of mini-grids’ technical performance is a critical requirement. The Guide offers the standardized protocols to follow in order to construct a detailed and far-sighted assessment of a mini-grid’s health and the appropriateness of its underlying design.
“We foresee every step of monitoring becoming increasingly streamlined: from data collection, to benchmarking, to interpretation, and hence to confident prescription of interventions which will improve and safeguard performance,” added Mr. Mukherji. The Guide seeks to support the knowledge base of various stakeholders in the broader mini-grid ecosystem, including technical services companies, equipment manufacturers, regulators, and investors. Currently, in the absence of any standard established monitoring framework, new entrants to the sector are forced to commit to a period of experimentation in how to track and manage performance. This leads to cost inefficiencies and mistreatment of equipment. This Guide helps mini-grid developers avoid elementary pitfalls, providing a foundation that can be built upon and adapted as they gain more experience in the capabilities and requirements of the equipment on the market.
Mini-grid plant monitoring consists of three complementary activities.
1. Technical Audit: A deep and thorough evaluation of plant equipment, architecture, and operations requiring a visit from a specialized audit team. A technical audit provides a detailed snapshot of the plant at a given point in time, providing a baseline for future investigations. It also outlines corrective measures and projects future performance.
2. Routine Monitoring: Local mini-grid field personnel need to monitor the plant components. These activities maintain a proactive and continuous understanding of plant behavior and give opportunity for swift intervention before incipient problems escalate
3. Remote Technical Assessment: The tracking of specific technical indicators to reveal longer-term trends in the performance of mini-grids is critical. With remote data collection from in-plant sensors and automated analysis on cloud servers, these key indicators give continuous comparative insight into whether a plant is meeting expected performance.
The mini-grid sector as a whole has now developed to the point where routine technical audits and monitoring are indispensable for both aging and newly-built plants. The root causes of underperformance can in some cases be revealed through a single approach alone, but typically insights from all three must be combined to arrive at a complete picture. Once underlying issues have been identified, short- and long-term solutions can be devised; weighing the benefits and costs of these, plant management can optimally allocate their resources in correcting the performance of existing plants and revising the design of new builds
This Guide lays foundations for development and implementation of a variety of assessment approaches. Mini-grid technologies continue to mature, and the range and quality of sector specific services continue to improve, making valuable contributions for the development of the sector.
