Show us your Logs! Why Offtakers Should Demand Solar Maintenance Logs.

A well-thought-out maintenance strategy gives developers confidence they can generate the renewable kilowatts they sold in their Power Purchase Agreement contract. Utilizing purpose-built maintenance management software provides the developer (IPP) a competitive advantage. Field data and maintenance tasks can be photographed and recorded in real-time and archived for retrieval at any time. Having this critical data to hand gives the offtaker confidence in the transaction. 

 

 

PV Solar Failure Rates

"On average, solar panels degrade at a rate of 1% each year, which guarantees 90% production in the first ten years and 80% by year 25 or 30." - Paradise Solar Energy.


Based on this statistic, if the developer sells to an offtaker within 5years, by which time, his solar panels will have degraded by 5%, thus decreasing revenue-generating output. Rates of solar panel degradation increase if not properly maintained and cleaned. The offtaker blindly trusts that the developer has undertaken routine maintenance tasks. What if the developer could provide a substantial record of all maintenance tasks and check adequate cleaning and how often?

 

 

How Expensive is Failure?

Andy Walker from the US-based National Renewable Energy Laboratory (NREL) estimates that "the cost of O&M for old solar PV systems, was on average $20 per kW a year, whereas now it is closer to $7.50 per kW a year." - Power Technology.

 

The cost of solar panel operations and maintenance is currently at an all-time low. Developments in technology mean critical elements such as inverters are "more reliable with fewer failures", says Walker. Solar projects are usually associated with modest profit margins. Therefore, it is imperative to maintain low O&M costs to ensure your solar project remains commercially viable.

 

Let's say the developer decides to sell the solar system to an offtaker after 5years of neglecting his solar panels. His lack of vegetation management led to a breed of fast-growing weeds swiftly taking over a third of the solar arrays, damaging a number of them in the process. Blossoming flowers left panels dirty and pollen-damaged. This damage can reduce efficiency by up to 30%. Once again, the offtaker is taking on the risk having received no evidence of maintenance management carried out on site.

 

 

Become a "super offtaker"

"Offtakers have wide-ranging levels of creditworthiness. At the high-end of the credit spectrum are public companies like Google, Apple or Microsoft. They are like "super offtakers" because they have impeccable, investment-grade credit, and they buy a ton of renewable energy!" - Rob Freeman What is an Offtaker?


Offtakers must demand more from developers. Not only could these long-term project owners accumulate substantial savings in initial maintenance checks, but the offtaker avoids the risk associated with their long-term ownership. There is also potential to gain increased margins from their renewable energy investment.

IPPs are responsible for demonstrating accurate, timely maintenance logs, checks, completed jobs, photo evidence, and data collated from their assets. Often an IPP will subcontract to a maintenance company. The endeavour ensures asset longevity and creates a good relationship between themselves and the offtaker. Built trust helps create a reliable reputation in the marketplace, thus potentially generating future sales via word-of-mouth. It is clear how simple cleaning of a solar panel can reap small percent increases in a generation which add up across a sizeable portfolio of sites.

 

 

How can Preventative Maintenance Software Help?

 

"In an era where more than 80% of companies have experienced an unexpected outage in the last three years, having a clear, defined, and well-thought-out maintenance plan is a crucial first step for setting up a business for long-term success." - Coast, What is Predictive Maintenance?

 

Coast explains that, traditionally, renewable energy asset maintenance relied on pen and paper for routine documentation and data communicated via crude software such as WhatsApp and Excell. While many utilities may have an "if it's not broke, don't fix it" mentality, these platforms have proved challenging to track historical maintenance records and take a great deal of time to update and keep teams informed.

 

Implementing preventative maintenance software demands less time tracking solar array systems manually, makes scheduling work orders simple and allows technicians easy access to historical data at the touch of a button. Incorporated customized alerts suit your site's unique needs. Tracking work orders and tasks will present comprehensive data trends to help optimize your maintenance strategy, saving more time, money and future failures.

Continuity of Operations: the Covid-informed small rural utility

Posted by Tonya James

4/13/20 6:30 AM

Today, even small, rural utilities and microgrids must implement their Continuity of Operations Plans (COOPs). However, many are realizing that the threat of a global pandemic ranked low in initial threat assessments compared to earthquakes and tsunamis. Conversations among operations managers and utility leadership in virtual meeting rooms echo references to Continuity of Operation Plans (COOP) and what their peers are doing. It’s no small feat to determine what extreme measures should be put in place to prepare for the uncertainty before them.

Operadores De Campo A Distanciamiento Social Indefinido

Posted by Piper Foster Wilder, CEO

4/7/20 11:57 AM

Esta semana, NBC noticias informó que el Operador del Sistema Eléctrico Independiente del estado de Nueva York (NYISO) promulgó su Plan de Continuidad para distanciar socialmente a 37 empleados y de esta forma garantizar su salud. Este personal de operación y mantenimiento de NYISO contará con remolques para dos personas durante sus dos turnos, para refugiarse mientras realizan su trabajo. Los remolques están equipados con camas, alimentos y provisiones. El propósito es conservar la salud de los empleados y, por lo tanto, su capacidad para mantener también la salud de la red de servicios públicos de Nueva York de la que se abastecen casi 20 millones de neoyorquinos. Recordemos que son personas de carne y hueso las que se encargan del mantenimiento, supervisión y control de esta infraestructura crítica de servicios públicos. Si no se protege su salud, las líneas eléctricas, las subestaciones y el mantenimiento del equipo de generación se convierten también en víctimas del COVID-19. El Edison Electric Institute ha pronosticado que hasta el 40% de la fuerza laboral de servicios públicos podría no poder trabajar, ya sea que esté enfermo, quedándose en casa o cuidando a la familia. La investigación realizada por 60Hertz revela que las empresas de servicios públicos y los operadores de sistemas independientes en todo el país están considerando adoptar medidas similares.

Two-to-a-Trailer with No End in Sight

Posted by Piper Foster Wilder, CEO

4/3/20 2:41 PM

This week, NBC reported that New York’s Independent System Operator enacted its Continuity Plan to isolate 37 employees from society to ensure their health. Two shifts of these NYISO operations and reliability staff will be holed-up two-to-a-trailer for the foreseeable future. The trailers are equipped with beds, food and provisions. The purpose is to retain employees’ health, and therefore their ability to maintain the health of New York’s utility grid on which almost 20 million New Yorkers rely. Remember, it’s people who maintain, monitor and control this critical utility infrastructure. Without protecting their health, the power lines, substations, and upkeep of generation equipment become a victim of COVID-19. Edison Electric Institute has predicted that up to 40% of the utility workforce could be unable to work, whether out sick, staying home, or caring for family. 60Hertz’s research reveals that utilities and Independent System Operators across the country are considering enacting similar measures.
