Utility scale design and engineering

Challenge: A State electrical regulator launched a bidding process to build solar power plants of 5 MW to be connected to the mid voltage system in several locations where the energy would be directly consumed. Every location had a sub – station with enough capacity to connect the solar power plants. In this scenario, a private investor chose us to develop 4 projects for different locations.
Solution: We designed and made the engineering for four (04) projects, including but not limited to Descriptive Memory, transformers sub-stations, cabling, land agreements, soil studies, environmental permits, legal entities, inverters and connection strings, tilt fixed structures design and calculations, financial planning, project planning, import planning, vendors agreements, among others.

Challenge: The customer not just need an energy backup for its gas station but, also required a kind of UPS function to not miss the in-process data of vehicles being charged when an outage happened. Outages became more frequent every time.
Solution: We analyzed lot of storage options available at the market and designed a solution through combining parameters in a storage system to reduce its reaction time to around 100 ms, which provides the required energy to each charging station faster enough energized to not miss the data and continue providing the gas charging without issues for customers.

Challenge: Electricity bill of the customer included huge tariff rates for mainly three concepts, contracted power, demanded power and demanded energy, with a business model that operates with full loads during light hours and that is significantly reduced during dark hours, those payments had a significant impact on its business costs.
Solution: We designed and installed a solar system that provided the demanded power and enough energy as to cover +85% of the demanded energy. As a result, the business owner was able to re – negotiate the contracted power, getting important costs reductions from the three of the bill concepts. As a point to highlight for this business owner, he became the witness case installation of the first bi – directional meter at town and in which payment for the energy injected into the network was recognized under a net billing scheme.

Challenge: The customer built her family dream’s house in a polo horse breeding to enjoy the landscape, weather, and peace. With more than 5 cool/heat Air Conditioners, swimming pool and lot of electrical appliances but however, the house had no opportunity to get connected to the grid because it is so far from any grid connection.
Solution: Considering the family had two babies, we deeply analyzed the loads and their potential concurrent scenarios to provide the right surge, power and energy required to keep safe and comfortable the family 24×7. As a result, we designed a 15 kW off – grid system with enough kWh of storage to ensure the home has the demanded electricity during nights, rainy or cloudy days.

Challenge: The customer was looking for a solution that allow him to use as much solar energy as possible, feed to the grid with the exceed and get paid for that energy. A while after installed an on-grid system, the customer also wanted to get available enough energy as to run during an average outage of 8 hours, those outages had become more frequent during the summer.
Solution: We first installed a 10 kWp on – grid solution that feed enough energy to the home and send the exceed to the grid. To the new requirement and to not replace the already installed inverter, protecting customer investment, we design a retrofit system with the corresponding 10 kW 3 phases inverter + 12.5 kWh storage that perfectly complemented the on – grid system. Ensuring the customer, the demanded power plus energy during outages periods.

Challenge: The customer got surprised with every new invoice because he unknown the cause behind ups and downs in them, he wanted to know what his consumptions by appliance and their impact were to then apply an energy efficiency approach at home.
Solution: We designed and installed a 5 kWp hybrid solar system able to align a high % of customer’s demand by season and an IoT solution that allowed him to monitor the whole consumptions split by appliance and electric outlet, on/off them, monitor generation and grid consumption, among other functions. The system includes storage and it is able to send the exceeded energy to the grid under a net billing scheme.
