At RE+ 2023, leaders, innovators, and stakeholders in the renewable energy sector gathered to explore the latest advancements, challenges, and opportunities in the field. Despite the many booths, presentations, and discussions, several key themes emerged, offering clarity on the present state of the industry and its trajectory moving forward. Here are some of Pure Power’s key takeaways from the event:
### Labor Costs and Value Engineering
The rising labor costs in the renewable energy sector have somewhat offset the decline in module prices. Rooftop installation expenses have surged significantly due to increased labor costs. In response, value engineering has become essential for developers and EPCs looking to reduce overall project expenses. Pure Power’s emphasis on value engineering design and its team of over 90 engineers focused on enhancing project efficiency is seen as a critical advantage in this environment.
### Switchboards: A Persistent Challenge
A major issue in the renewable energy sector is the prolonged lead times for switchboards. Delays in receiving switchboards can disrupt project schedules and drive up costs. To address this, the prevailing wisdom is to adopt multiple disconnect switches and panel setups, particularly for smaller projects. This approach minimizes reliance on a single supplier, reducing project risks.
### Fire Resistant Boards: Enhancing Safety
An interesting development highlighted at RE+ 2023 was the use of fire-resistant boards beneath string inverters on rooftops. These boards act as a protective layer, mitigating potential damage to roofs and buildings during fires. Notably, companies like Amazon have implemented this practice at certain sites, signaling a growing focus on fire safety in renewable energy installations.
### The Evolution of BESS
Battery Energy Storage Systems (BESS) are rapidly transforming, with many string inverter vendors entering the BESS market with all-in-one turnkey solutions. Similarly, module manufacturers are exploring BESS options. While there was once a strong demand for DC-coupled storage, this trend seems to be waning. Clients are now more interested in utility-scale projects ranging from 30MW to several hundred MW, actively seeking partners for these ventures.
### Shifting Trends in DC-Coupled Storage
Enthusiasm for DC-coupled storage projects has cooled, likely due to compatibility concerns. Unless manufacturers begin offering integrated PV and BESS solutions, standalone BESS projects are becoming more common. Clients prioritizing cost-cutting without fully leveraging service providers’ offerings may miss out on additional value.
### Rise in Standalone BESS Projects
There is a noticeable increase in standalone BESS projects in development, typically ranging from 3 to 5MW. Some clients have ambitious goals, such as developing 2.5GW over the next five years or dozens of projects aiming for substantial completion by 2025. However, supply chain challenges for switchboards and transformers remain significant obstacles.
### Abundance of Project Opportunities
Attendees at the conference agreed that a wealth of renewable energy projects are ready to be designed and executed. These are not merely theoretical ideas but tangible projects entering their pipelines. Clients expressed confidence that Pure Power is the sole company in the industry with the necessary engineering expertise and efficiency to meet their project deadlines. By contrast, competitors lack the same capacity, with PPE boasting over 90 electrical engineers and a team of 19 Professional Engineers and Project Managers.
### Balancing Cost and Quality
While some clients acknowledge that Pure Power may be more costly, they recognize the value it provides. Many have experienced the negative impacts of cheaper but inferior engineering. For larger sites and portfolios, the consensus is that partnering with an experienced and reliable firm like Pure Power Engineering is the best way to maximize energy generation revenue while minimizing project costs.
### Utility-Scale Inquiries and Expectations
On the utility-scale front, clients commonly inquire about PPE’s capabilities and experience with Utility-Scale Solar + Storage projects. Questions often center around project sizes, locations, and the EPC partners involved. Pure Power has six high-level engineers dedicated to utility-scale projects, having completed ten project engineering designs in the past year.
For instance, Pure Power provided the electrical engineering services for the 238 MW DC Escalante utility-scale PV plant. This included power system analyses, cable thermal assessments, short circuit evaluations, load flow and reactive power analyses, grounding assessments, arc-flash analysis, and PVSYST modeling.
In summary, RE+ 2023 offered valuable insights into the renewable energy sector’s challenges and opportunities. As the industry continues to evolve, companies must remain flexible, responsive to market trends, and committed to delivering high-quality solutions.
