CASE STUDY: Solar O&M and Land Management with a 50% Cost Reduction

Location: Southern California | Acreage: 3000 | Energy Capability: 550MW of solar power

solar o&m - WWS provides solar o&m solutions to utility scale solar farms

Initiative #1: Quickly execute solar O&M land management for a utility-scale solar farm so electrical construction could be completed on schedule.

Initiative #2: Develop a vegetation management strategy that allowed the solar farm to stay ahead of schedule, proactively manage 3000 acres of grass and weeds, and save on mowing costs.

A solar farm in Southern California contracted World Wind & Solar (WWS) to handle an immediate need for weed abatement at their 3000-acre utility-scale solar project. Four-foot-tall tumble weeds needed to be quickly cleared from under the panels, the cable trays and the combiner boxes before electricians could complete electrical construction. The weed overgrowth also posed a fire hazard in the dry California heat and was a breeding ground for snakes, spiders and rodents, posing a heightened level of complexity and further mandating immediate removal.

WWS deployed trained crews with custom commercial mowing equipment and hand tools to mow the entire site, including hundreds of acres of brush and large tumbleweeds. The tumbleweeds were entangled under solar panels and critical equipment, requiring precision cutting from the WWS team. WWS coordinated efforts with the project owner, the O&M team, the construction company and their contracted electricians to ensure all vegetation removal occurred a week ahead schedule, thus allowing the electricians to easily complete connections. solar o&m - WWS provides solar land management and revegetation solutions to a solar farm in CaliforniaAfter the immediate mowing needs were mitigated, further inspection of the site suggested that more land maintenance was necessary if the solar farm wanted to prevent invasive plants like Russian Thistle from taking root. WWS worked with the site solar O&M team to create a vegetation strategy that ensured land maintenance was performed per the project’s conditional use permit. This strategy included the use of patented custom mowing equipment designed and developed by WWS. Our specialized equipment expedited mowing and allowed the O&M team to cut more acres in less time and with less manpower. Because WWS’s equipment is designed to lower manpower needs, health and safety concerns such as heat stroke and heat stress were reduced. Additionally, WWS’s custom equipment controlled the site’s overabundance of Russian Thistle far better than traditional commercial equipment. Another key aspect of the land management strategy was the “Inspection of Watch” program – a WWS-developed methodology that leverages the mowing crew as additional sets of eyes for the solar O&M provider and results in early detection of mechanical or electrical issues in the field. WWS identifies and marks the affected components then reports this to the control room, thus expediting a solution and reducing component downtime. By cross-training our land management crews with general solar O&M skills, WWS has been able to resolve low-impact solar O&M issues while managing manpower and site maintenance responsibilities. This saves the solar O&M team a truck roll and returns the site to full production more quickly. Vegetation maintenance is one of the most important – yet overlooked – aspects of managing a solar farm. Once unwanted plants and the organisms they host gain a foothold on your site, they become difficult to control and negatively impact solar O&M budgets. Additionally, this type of utility-scale land management needs to be handled by professionals because mowing thousands of acres inside energized solar arrays – while navigating solar panels, pylons, tracking systems, electrical cables and other critical site components – is a unique skill set. Since 2015, WWS’s land management expertise has helped this site reach a large degree of success – the new equipment and efficiencies we developed have cut mowing costs by 50% and allowed the site to meet rigorous revegetation requirements. Our dependable equipment and knowledgeable staff have been paramount in protecting all employees and site assets.

Generating solar power profitably depends heavily on plant performance and the reliability of equipment and related plant components. While free-field power plants today are highly reliable, requiring minimal manpower, production losses from a variety of failure points can dramatically impact electricity production and financial performance. To minimize risk O&M crews must continually monitor key components, conduct scheduled maintenance tasks on time, and urgently respond to unscheduled repairs and unforeseen problems, like weather or soil related issues that threaten assets, the environment, and plant output.

At WWS we deliver cost effective solutions designed to ensure maximum productivity with minimal downtime for our partner clients by cultivating the industry’s best and brightest workforce, utilizing industry best practices for scheduled and unscheduled maintenance, conducting site inspections, and diligently monitoring equipment performance and environmental threats to proactively circumvent problems and eliminate downtime risks.

Focus on the Future of Utility Scale Solar Plants

According to SEIA, utility-scale solar plants represented nearly two thirds of market production over the past few years, and this trend is expected to continue through 2017 with a contracted pipeline of projects exceeding 20 gigawatts.

The SEIA expects the U.S. solar industry to install 13.9 GW of capacity by the end of 2016, which is nearly double the amount installed in a record-breaking 2015. Through the end of this decade, there will be robust growth across all three market segments, eventually reaching a 20 GW annual solar market.
