Women in Engineering: Exploring the Research

Posted on 23 August 2024 by Joanna Wrzeszcz

On June 23rd, two months ago, we celebrated International Women in Engineering Day. Established in 2014 by the UK’s Women’s Engineering Society, this day aims to increase the visibility of women in the engineering field. At Electrum, we thought, “What if the 23rd of every month became Women in Engineering Day?” 📢

Thus, on the occasion of another 23rd day of the month, we highlight some studies that, in our opinion, well illustrate what we should focus on to encourage more women to pursue careers in engineering and why this is so important in the context of the entire Climate Tech industry.

We start with quite positive data released by the European Union’s statistical office, Eurostat, in February this year: In Poland, in 2022, depending on the region, the percentage of female scientists and engineers ranged from 53% to 61%. In this regard, we outperform countries like the United Kingdom and Germany. The macro-eastern region, where Electrum is located, can boast 59%. However, data specifically on female engineers is somewhat less optimistic. According to the “Statistical Yearbook of Labour 2023,” a report prepared by Poland’s Central Statistical Office, women account for about 35% of all engineers in Poland. Bergman Engineering decided to examine their situation in Poland’s largest enterprises—after analyzing LinkedIn profiles, they found that the employment of female engineers in these companies may be as low as 16%.

Gender disparity in engineering environments worldwide, of course, varies by profession but is generally well-documented—it’s an issue that requires improvement because the benefits extend far beyond equality in statistics.

We believe that a truly sustainable future begins with diverse teams working towards it. To enjoy our planet’s beauty for as long as possible, it is essential to collaborate with highly talented and diverse teams of professionals. This means attracting and retaining women and other minority groups in science, technology, engineering, and mathematics (STEM) careers, which play a fundamental role in the Climate Tech industry.

In 2020, the report “Women in Technology 2020” was published, carried out as part of the Shesnnovation Academy program by the Educational Foundation Perspektywy and Citi Foundation. The study surveyed a thousand Polish women identifying with the STEM field, where, overall, no more than 25% of women are present, as researchers indicate. According to the authors of the report, the role of women in the new technology sector is steadily growing, and this change is happening “from the ground up,” starting at the lowest levels. More and more women are choosing engineering studies. Over the ten years preceding 2020, the number of women studying at technical universities increased by 10%. It is worth noting that the number of female students at these universities is growing twice as fast as the number of male students. More women are also entering the high-tech industry, taking on higher management positions. The report described these changes as a “creeping revolution.”

How can this be supported, and how can we facilitate entry into the industry for those leading this change? The study “Mentorship in Engineering: Women, Inclusivity and Diversity – A challenge for our times,” conducted in 2023 by Breda Walsh Shanahan and Mary Doyle-Kent, highlights the key role of mentoring in this process. Mentoring not only supports theoretical development but also builds a sense of belonging. The study’s conclusion reads that regardless of gender or stereotypes, a novice female engineer or STEM graduate can develop her skills and benefit from the experience of a mentor who knows the professional culture and specifics. This strengthens the foundations of a more sustainable and diverse work environment. Another factor that promotes this is the overall visibility of positive role models who can encourage women to pursue an engineering path—their role is crucial both in the early years and in specific professional environments or companies.

In 2018, a report titled “Climate Control: Gender and Racial Bias in Engineering” prepared by the Society of Women Engineers presented findings that should certainly heighten awareness for all interested in this topic. The report was based on an examination of the biases women and people of color face in engineering workplaces. Hidden or unconscious biases can negatively impact the workplace atmosphere, influencing decisions regarding hiring, promotions, and compensation for women and other underrepresented minorities in engineering, preventing them from reaching managerial and senior management positions. Research indicated that nearly 40% of female engineers leave the profession mid-career. We believe that in 2024 the situation is improving, but it is still crucial to pay attention to all forms of discrimination in the workplace and effectively counteract them. This is also a well-documented issue and addressed by many reports and studies. The role of a modern company is to anticipate this and support the revolution that brings us closer to a better future.

Another key issue is that diverse teams mean a better work environment and, simply put, better results. This is not just about gender—age, cultural background, and different areas of expertise also matter. We are close to the statement that diversity of perspectives leads to more comprehensive problem analysis and better solutions. However, McKinsey & Company’s research “Diversity Wins: How Inclusion Matters” emphasizes that diversity alone is not enough. It is essential to create an inclusive work environment where all employees feel valued and have equal opportunities for development.

We hope that the work environment we create at Electrum is perceived this way among our employees. Looking ahead, we see the need to align with the philosophy of Industry 5.0—a new era of industry where technology collaborates with humans, and diversity and sustainability become key elements. One step we see on the horizon is considering how to effectively attract more female engineers to our team.

We also want to take a closer look at how female engineers already employed with us feel. Following another report by McKinsey & Company, “Women in the Workplace 2023,” we want to track outcomes that support the development of women. As in other areas of our activity, in terms of diversity and inclusivity goals, we want to focus on transparency. We know that this not only motivates engagement but also strengthens the sense of support in the organization, which supports the long-term professional development of minority members. These are issues worth considering if the ultimate goal is to most effectively support innovation. This is a pillar on which the entire Climate Tech industry continuously stands (and we stand with it).

Of course, it would be a mistake to conclude that the challenges women face in engineering are limited to this industry. This is part of a broader social model, whose change requires our concrete actions. But before we take them, it’s worth considering how and why the world around us looks the way it does. Then, think about how we can contribute to making it easier for future generations of women—and today’s girls—not only in historically and currently male-dominated fields but essentially in the society we are building today.

At Electrum, we want to build a truly sustainable, innovative future and harness the full potential of what can guarantee it.

Hybrid renewable energy systems – An Interview with Kamil Kozicki

Posted on 22 August 202422 August 2024 by Joanna Wrzeszcz

Hybrid renewable energy systems are facilities that use more than one source of clean energy generation. These are advanced systems that combine different renewable technologies, such as solar and wind energy, to increase production efficiency. In Poland, due to favorable weather conditions, we most often invest in solar and wind energy.

In the long term, we can expect various combinations of energy sources, such as water-sun or water-wind connections. However, at the moment, the most accessible and efficient solution is a combination of solar and wind energy, which complement each other perfectly, enabling stable energy production throughout the day.

Other technologies, such as pumped-storage power plants, which rely on water-generated energy, are less common in Poland. Pumped-storage power plants require specific geographical conditions and significant initial investments, limiting their widespread use.

One of the first large-scale hybrid power plant in Poland is the Kleczew Solar & Wind Park.

We talk with Kamil Kozicki, an expert from Electrum, about Kleczew and explain how modern hybrid installations contribute to the energy transition. We also discuss the current legal status of such installations and the reasons why investing in them is worthwhile.

How does the Kleczew Solar & Wind Park work?

In Kleczew, we have two integrated energy sources: a photovoltaic (PV) farm and a wind farm. The PV farm has a maximum capacity of 193 MW (AC), with an installed capacity in the PV modules of 250 MWp. This means that the system is oversized by 30%, allowing for stable energy supply even under varying weather conditions. The second facility, the wind farm, consists of four Nordex N133 turbines, each with a capacity of 4.8 MW, totaling 19.2 MW of installed capacity. However, due to connection limitations, we can currently only deliver 11.7 MW of wind power. The connection capacity, or the maximum power we can deliver to the grid based on the connection agreement, is 204 MW for both energy sources combined.

The common point of connection between the PV farm and the wind farm is the Main Offtake Point (GPO). Thanks to the hybrid installation, the energy produced by these farms is transmitted via a single high-voltage cable. This optimizes transmission infrastructure and reduces costs.

How does Kleczew stand out among other hybrid facilities in Poland?

It is the first farm on such a large scale. The first with connection terms issued that explicitly indicate two energy sources in the connection agreement. This means it was clear from the beginning that this is a hybrid facility. Previously, micro-installations combining photovoltaics with a few wind turbines were developed, but here we have a large-scale facility with 250 MWp of solar power and 19.2 MW of wind power (installed capacity). The facility is controlled by Electrum’s proprietary solution, the Renedium master controller, enabling the creation of a unique ecosystem.

So, before Kleczew, connection agreements did not include two energy sources?

Until now, the connection agreements and connection terms I dealt with at Electrum specified a single energy source. Kleczew is the first wind solar farm we have implemented where two energy sources are explicitly defined – it was designed and implemented as a hybrid installation.

A single transmission line for two sources is also used in cable pooling. How do hybrid installations differ from cable pooling?

Both approaches aim to optimize the use of renewable energy, but they differ in methods and infrastructure. Cable pooling focuses on using transmission infrastructure by sharing a single line between different renewable energy installations. However, these installations are independent of each other and cannot fully utilize their potential. Therefore, wind solar farms go a step further. They integrate different renewable technologies in one location to increase the reliability and efficiency of energy production. It is an entire system designed to complement each other and work together.

Kleczew is designed to effectively utilize the available renewable energy resources under different weather conditions. Both installations operate simultaneously. When the PV farm is not working due to weather conditions or time of day, the wind farm operates, and the facility continues to generate renewable energy, ensuring continuous production.

In cable pooling, the wind farm could share a line with the photovoltaic farm, using the same transmission infrastructure to reduce costs, maximize productivity, and increase profits for the investor. As a solar wind hybrid system, Kleczew not only shares infrastructure but also combines different renewable energy technologies in one location. Photovoltaic panels and wind turbines are integrated to complement each other, providing more stable and efficient energy production throughout the day. Moreover, as I mentioned, the agreement clearly defines that it is a facility with two energy sources.

What is the process of testing and commissioning a hybrid facility?

We are subject to standard network code procedures that we must follow. These apply to all stages, from obtaining permission to energize (EON), through temporary permission to operate (ION), to final operational permission (FON). At Electrum, we comprehensively carry out all the procedures necessary to commission the facility, from conducting necessary simulations to performing compliance tests. To ensure everything runs smoothly, SCADA-type software* is also required. In Kleczew, Electrum’s proprietary solutions – the EMACS software and Renedium, which houses a built-in master controller that integrates all energy sources, overseeing and controlling them.

* Supervisory Control And Data Acquisition

What problems do solar wind hybrid power solve?

A wind farm can operate continuously, regardless of day or night, depending on wind conditions. The solar farm, on the other hand, operates at specific hours, dependent on the sun. The key word here is efficiency. Primarily, hybrid installations allow more efficient use of connection capacity and, to some extent, can substitute solar with wind or wind with solar. In Kleczew, we have not yet fully utilized the connection capacity, and together with the investor, we are working towards that goal.

Does Electrum intend to focus on renewable energy hybrid systems?

We will certainly encourage investors towards such solutions. It is an attractive prospect – fully utilizing connection capacity and maximizing profits. There are projects under discussion, such as adding wind turbines to an existing solar farm.

What currently holds investors back from hybrid projects?

Primarily issues related to connection agreements and issuing technical connection conditions. The process requires the investor to first approach the electricity network operator and obtain approval for a renewable energy hybrid systems. At this stage, various nuances arise, such as the definition of a hybrid installation and the lack of uniform regulations. Whether it will be a hybrid, where a wind farm is expanded with solar power or vice versa, or a new independent installation connected to another in a cable pooling option. Currently, regulations governing hybrid installations are in the process of being developed. There is a lack of uniform, general guidelines that clearly define technical requirements, procedures, and standards. As appropriate regulations develop and support for hybrid projects increases, these barriers may gradually be reduced. This will open the door to broader application of hybrid installations. Of course, this does not mean that the current barriers cannot be overcome. Kleczew is the best example of this.

Which country sets a good example?

A great example from abroad is Denmark, a leader in hybrid power plants. Denmark successfully operates hybrid renewable energy farms that combine wind turbines with photovoltaic installations and energy storage systems. For example, the hybrid farm in Lem Kær, which integrates various renewable energy sources and energy storage systems.

An energy storage system is also planned for Kleczew. How will energy storage impact the installation?

Introducing energy storage will allow us to overcome the current limitations imposed on the farm. The photovoltaic farm in Kleczew has a capacity of 250 MWp, of which we can effectively use 193 MW. A similar situation applies to the wind farm – out of four turbines with a capacity of 4.8 MW each, we can effectively use only 11.7 MW. These limitations result from the connection agreement. The facility can continue to be expanded. Currently, we have 204 MW of connection capacity, and we are ready to continuously transmit 240 MW to PSE.

Energy storage will allow excess energy that currently cannot be transmitted to the grid due to contractual limitations to be stored. In practice, this means that surplus energy that cannot be directly utilized will be stored. In moments when energy production from solar and wind is lower, the energy storage system will be able to release the stored energy to the grid. This will allow for more consistent energy delivery to the grid, avoiding sudden drops and spikes in power.

Energy storage will enable more efficient management of the farm’s energy production. Solar energy is produced mainly from late morning to early afternoon, after which it decreases. Wind energy production, on the other hand, can be more variable. Energy storage will smooth out these fluctuations, allowing energy to be delivered to the grid in a more stable and consistent manner.

Introducing energy storage also opens up possibilities for further expansion of the farm. With energy storage, we can increase the installation’s capacity. Excess energy can be stored and used during times of higher demand. For example, if we have 204 MW of connection capacity, the storage system will allow us to maintain maximum power for longer periods under ideal conditions at midday when energy production is highest.

Are hybrid renewable energy systems the future of renewable energy? Is this the direction in which renewable energy will expand more broadly?

It is certainly one of the directions. It all comes down to making these energy sources as flexible and efficient as possible. The demand for energy from the grid is not uniform. There are hours when energy is needed more, and others when it is needed less. The broader application of hybrid farms, additionally with energy storage, will allow for better alignment with demand.

Another related issue is the distribution network in Poland. We have problems with energy transmission. On weekends, there is usually too much energy. That’s the situation we have. The operator does not want to receive this energy on weekends and signals to shut down or limit production from the farm. In the worst case, penalties and negative energy prices may appear during this time. If we have a hybrid renewable energy systems with energy storage, we can adapt our production to the conditions – shut down or reduce the power of the photovoltaic installation while the wind farm continues to operate.

The hybrid power plants can also operate entirely independently of the grid. With energy storage, we can store energy and utilize it according to our needs without relying on the grid operator.

In the long run, we can expect hybrid power plants to become more widespread. Investors and operators will increasingly rely on these advanced energy solutions. Hybrid systems can provide more flexible and efficient energy production, especially with energy storage, and become an important part of Poland’s energy mix.

How to start a solar farm? Step by step guide

Posted on 19 July 202431 October 2024 by Joanna Wrzeszcz

In this article, we present the key steps how to start a solar farm. Building a solar photovoltaic power plant is certainly not easy. Most stages require the help of specialists, but before reaching out for their assistance, it is worth understanding the process of constructing a solar farm.

The stages of establishing a solar farm can be divided into design stages (site selection, administrative procedures, construction design) and execution stages (solar farm and accompanying infrastructure construction, electrical connections and testing). Following these stages, there are also aspects related to the effective management of the installation, which will impact the future of the farm.

Quick Facts:

In 2023, solar installations accounted for about 60% of the installed capacity in the entire renewable energy sector, according to the latest report from the Institute of Renewable Energy. This means that photovoltaics lead the way in the renewable energy sector.
By the end of 2023, Poland’s photovoltaic capacity reached 17.08 GW, saving around 23 million tons of CO2 emissions, according to the IEO report.
Based on photovoltaic installation capacity, we distinguish between small and large farms. A small farm is an installation with a capacity ranging from 50 kWp to 1 MW. A large photovoltaic installation has a capacity above 1 MW.
A photovoltaic power plant is an installation with a capacity of 1 MW or more.
To install a 1 MW photovoltaic power plant, approximately 2 hectares of land are required.

How to start a solar farm? Design Stages of Creating a solar power plant

1. Choosing the Location: Finding the Right Land for Photovoltaics

Where to begin? The most important step is choosing the location for the photovoltaic farm, which must take into account many factors such as land suitability for the investment, sunlight availability, and proximity to the grid infrastructure. A suitable location for a photovoltaic farm is one that primarily:

Utilizes land with low agricultural value (requirements for solar farms include land of class IV or lower), which does not block areas capable of food production, simplifies administrative procedures, and also reduces the investment cost.
Is well-sunlit, where sunlight availability is the measure of the amount of solar energy reaching the Earth’s surface within a specified time, expressed in kilowatt-hours per square meter (kWh/m²) per day. Determining sunlight availability allows for a preliminary assessment of how much solar energy can be converted into electricity using photovoltaic panels, and thus a preliminary assessment of the photovoltaic farm’s profitability.

It allows for the proper placement of PV panels, which is best ensured by flat terrain; however, it is possible to optimally utilize land with a slight slope towards the south.
Proximity to grid infrastructure is another important factor, which means more favorable conditions for connecting the photovoltaic farm to the power grid. This directly impacts the construction costs and profitability of the photovoltaic farm. Locating the farm near existing transmission lines and transformer stations simplifies the procedures, so the recommended distance of the investment from the power grid is a maximum of 200 meters. Specific requirements for this distance may vary depending on local regulations and technical possibilities.
It is located at an appropriate distance from residential buildings or public utility areas. It is generally accepted that the minimum distance from buildings is about 100 meters, which minimizes potential nuisances related to noise and light reflections. Actual requirements may depend on local regulations and the specifics of the project.

2. Project Procedures: Required Permits and Legal Regulations

If you have a plot of land that meets the initial criteria for establishing a photovoltaic farm, it is important to verify whether a solar farm can be built on that area. This involves considering legal regulations, such as environmental conditions, the local zoning plan, or other administrative decisions for the land.

Local Zoning Plan

If a local zoning plan exists for the area, you must check whether it allows the construction of a photovoltaic farm. If the LZP permits the construction of solar farms, the investor must comply with all the conditions outlined in the plan. If the LZP does not allow for the construction of such farms, an application must be submitted to amend the plan, which can be a lengthy and tedious process. In the absence of an LZP, it is necessary to apply for a decision on building conditions.

Environmental Decision

Obtaining permits also involves securing an Environmental Decision (ED). This is required when the area covered by the outer edges of the panels exceeds 0.5 hectares in protected areas or 2 hectares in other areas. The requirements for obtaining an ED include conducting an Environmental Impact Assessment (EIA), which involves preparing an environmental report, holding public consultations, and obtaining opinions from various institutions. The decision is issued by the mayor, town mayor, or city president.

Building Permit

After obtaining the ED and meeting the requirements of the LZP, it is necessary to secure a building permit. This process includes preparing a detailed construction design and submitting an application to the appropriate architectural and construction administration authority. The building permit specifies the detailed building conditions for the photovoltaic farm, including the technical and legal requirements that the investment must meet.

Connection to the Power Grid

Required permits also include a document issued by the Distribution System Operator (DSO) or Transmission System Operator (TSO) that outlines the technical requirements for connecting the installation to the National Power System (NPS). This process involves a technical analysis, potential connection fees, and compliance with specified technical standards.

License

For commercial photovoltaic farms and those with a capacity exceeding 1 MW, a license for the production and further sale of energy from the photovoltaic farm is required. Obtaining a license involves submitting an application to the Energy Regulatory Office (ERO). This process includes presenting a detailed construction project of the photovoltaic farm, technical documentation, and obtaining the previously mentioned administrative and environmental permits. The license is essential for the legal operation of the farm and the sale of energy from the photovoltaic farm to the power grid.

Solar Farm Construction Project: Formalities Before Construction

Before obtaining a building permit, it is necessary to prepare a photovoltaic installation project, which involves creating detailed technical documentation, including the site development plan, architectural and construction design, and technical design.

Site Development Plan

The first step is to create a site development plan, which includes the layout of photovoltaic panels, access roads, technical infrastructure, and other elements necessary for the operation of the solar farm. This plan must take into account the topography of the land, its sunlight exposure, and the existing infrastructure.

Architectural and Construction Design

The next component is the architectural and construction design, which includes detailed technical solutions for the supporting structures of the panels, foundations, fences, and other construction elements. This design must comply with all building codes and technical requirements.

Technical Design

Simultaneously, a technical design is developed, which contains detailed information on the electrical installation, monitoring systems, fire protection, and other technical systems necessary for the safe and efficient operation of the photovoltaic farm. This design also includes the technical specifications of the equipment used and the materials from which various installation elements will be made.

Finding the right location, dealing with all the necessary administrative and legal steps, and creating various designs – the design process of setting up a photovoltaic farm is demanding. A sensible solution is to seek the help of specialists. At Electrum, we manage investment projects from concept to managing energy production from the photovoltaic farm.

How to Start a Solar Farm? Execution Stages of Creating a PV Farm

Once the building permit is obtained, the construction of the photovoltaic farm can begin, which involves several key stages. How do you start the construction?

1. Preparing the Site for Construction

The first step in building a photovoltaic farm is preparing the site for the installation of PV panels. This process includes removing any obstacles, leveling the ground, and preparing the foundations that will ensure the stability of the entire structure. The foundations must be properly designed and constructed to meet the requirements of the photovoltaic farm construction.

2. Installation of PV Panels

The next stage is the installation of the panels. The panels are mounted on the prepared foundations in a layout that maximizes the use of available sunlight. The construction of a photovoltaic panel farm must be precise to ensure the efficiency and durability of the solar power plant. The installation also includes setting up the supporting structures and systems to protect against various weather conditions.

3. Electrical Connections and Testing

After the panels are installed, the next step involves electrical connections and testing, which are crucial to confirm that the entire system is functioning correctly, meeting energy safety requirements, and complying with technical standards. The procedures related to electrical testing include verifying connections and checking the performance of the modules.

Once everything is ready, a visit to the Distribution System Operator is necessary to finalize the agreement and conduct the final inspection.

How Long Does It Take to Build a Solar Farm?

The execution phase of the investment takes relatively little time. For a 1 MW farm, this stage typically takes about 2-3 months. The most time-consuming part is the design phase, with a strong focus on obtaining approvals and administrative decisions. The entire process (both phases) can take up to 2.5-3 years.

Costs of Building a Photovoltaic Farm and Financing the Investment

The cost of constructing a 1 MW solar farm depends on many factors. Estimates vary based on variables such as natural conditions, project support costs, material prices, construction costs, and the price of systems and technologies used to manage the farm. The cost of such a farm can range between 2,000,000 and 4,000,000 PLN (440,000 to 920,000 EUR.)

If sufficient capital is not available, there are several ways to finance the construction of a photovoltaic farm. Besides loans, one option for securing funds is to take advantage of photovoltaic subsidies. The development of renewable energy in Poland and the growth of photovoltaic farms has led to increased opportunities in this area. Available options include, among others, EU Funds for 2021-2027, as well as regional programs.

How much to start a solar farm?

The profitability of a photovoltaic farm depends on many factors, including total construction costs, financing methods, production efficiency, and energy sales conditions, making it unique to each project.

To illustrate the earnings from a farm, we can use a simplified calculation. Assuming annual production of 1,100 MWh and a price of 600 PLN per MWh, the annual revenue can be calculated as follows:

1,100 MWh/year * 600 PLN/MWh = 660,000 PLN/year After 8 years, the total revenue would be: 5,280,000 PLN (1,160,000 to 1,210,000 EUR).

A photovoltaic investment can be very beneficial, especially in the context of growing demand for renewable energy and the availability of various forms of funding. After a few years, which yield a return on investment, the farm enters a period of steady and stable income, which is the profit from the farm.

Different types of solar power plants generate different revenues. Depending on the purpose of the farm’s construction and the business model, the energy produced by the photovoltaic farm may be intended for self-consumption or for sale.

Monitoring and Management

Professional management of a photovoltaic farm through effective monitoring ensures the maximization of profits, extension of the power plant’s lifespan, and helps reduce maintenance costs by enabling quick responses to potential issues.
