Dominican Republic opens bids for 600 MW renewables tender
The nation’s latest call for long-term power purchase agreements focuses on supplying the national grid with wind and solar projects, specifically mandating integrated battery storage systems to ensure grid resilience.
Managing cyber risks in the era of decentralized energy
The move toward decentralized energy resources offers resilience and flexibility in power generation, but it also introduces new complexities that demand proactive security measures.
St. Kitts and Nevis tenders major solar-storage project
The electric utility of St. Kitts is launching a tender for a 50 MW solar plus 30.5 MWh battery storage project on the island. Interested developers are asked to register on the utility’s bidding portal to receive the request for proposals document.
Fortescue fast-tracks delivery of ‘world first’ off-grid project combining solar, wind, up to 5 GWh of BESS
The rollout is accelerated to eliminate the use of diesel from iron ore mining and processing.
Cyber threats for PV: What are man-in-the-middle attacks and how do they work
Man-in-the-middle attacks are a serious threat to networked PV systems, allowing attackers to intercept, modify, or disrupt communications, potentially causing operational failures, physical damage, financial losses, and safety hazards. Effective defense requires a layered approach combining encryption, strong authentication, network segmentation, firewalls, IDS, and continuous monitoring to detect, prevent, and limit the impact of such attacks.
U.S. startup debuts low-cost, plug-and-play indoor heat pump for residential use
San Francisco-based Merino Energy has launched the Merino Mono, a plug-and-play indoor heat pump that can be installed in under an hour and is priced at a flat $3,800 including installation.
The Hydrogen Stream: BMW unveils tank for iX5 Hydrogen
BMW says its new hydrogen tank enables longer range and flexible production, while South Korea has revealed plans to develop large-scale liquid hydrogen storage systems.
Turkish manufacturer presents photovoltaic water heater
Adana-based WHS introduced a PV-powered water heating system that operates without an inverter, using 1.6 kW of direct DC solar input with integrated MPPT. The system supports hybrid operation with a 2 kW AC backup, runs at extra-low voltage of less than 50 V, delivers around 3 kWh/day of thermal energy, and heats water to 65–85 C for residential and small commercial use.
Solar PV, geothermal hybrid systems are more than niche solutions
Solar energy, driven by excellent resource conditions and rapidly improving economic attractiveness, is expected to emerge as a bulk energy supplier in future energy systems. The self-limiting effects of solar power can be circumvented through solar-hybrid solutions, such as PV-geothermal hybrid configurations.
