RENEWABLE ENERGY From Energetica India’s Blog Stable; Mar/Apr 2016 Energetica India brings forward the work of bloggers and contributors associated with Energetica India. The article collates thoughts/ideas/concepts based on the writers’ industry experience. NILESH PATEL CEO; MOVYA CONSULTANCY PVT LTD. (SOLAR PROJECT CONSULTING & LIAISON) ENERGETICA INDIA Real generation numbers from solar power plants speak about solar pv financial viability INDIA’S SOLAR PV FINANCIAL VIABILITY, REAL GENERATION FIGURES HAVE SPOKEN Gujarat in terms of infrastructure is most perfect state in INDIA and is second best state in terms of solar radiation after Rajasthan; a boon that the state has used optimally to install for solar PV plants. PV based power generation project. It’s been nearly 5 year since we saw country’s initial solar policy from Gujarat first solar policy from Gujarat actually showed way to entire INDIA on new era of renewable power generation after wind. A common calculation used by As most of our industry stakeholders is that 1MW should all Panel manufacturer marketed and consultant perceived, There has been wide acceptability or say thumb rule set for most of techno commercial survey or financial feasibility study done in Gujarat speaks 1 MW should minimally produce nearly 17-18 lacs Lakh (1.7 to 1.8 million) Kwh/year. Even SECI and MNRE bases their own calculations using these as benchmark by taking that figures in RfP’s while announcing any new solar capacity tendering across INDIA. But now It seems reality has spoken. The Second best radiation state, Gujarat having total of 66, commissioned in operation solar PV power plants Solar PV plant with different varying technologies ( though > 80% Crystalline). These plants have, in the year 2015, in one full year 2015, has shown an average generation of averaged out the overall Solar PV power generation at 15,89,211 Kwh/ year/ MW ( 1.59 Million Kwh/year/Mw) generation. A total of that is total 912.5 MW of solar installations project produced cumulative 1,430,937.616 Mwh power from solar panel in 2015 Below is the chart per MW generation for the year 2015; for solar power plants in Gujarat Look at below chart of per MW generation in 2015 from each of this developer of Gujarat. The source is Courtesy: SLDC Gujarat. All data represented in the chart are provided by SLDC, Gujarat. The generation number pertains to is data is billable units only excluding data only that means exclusion of self consumption which of power at plant which varies site to site from developer to developer project site. Low power generation does not mean poor performance. It may be due to transmission line outage, maintenance issue or other non-technical issue like plant shut down due to social unrest, theft at site etc. due to which generation cannot be recorded at SLDC. Key takeaways: Few take away points from these figures. 1. Konark plant has best generation among all with crystalline technology. 2. When I personally spoke to some of the developers of with few very low performing solar planter power plant owners, I found that the most major issues were I found they were running into one of the issue like se- energetica INDIA · MAR16 43
