Expertise in action: two project cases
Solar and storage
To measure the benefit of solar combined with battery storage for consumers and grid stability, Paul and his team supported an Enpuls project that involved deploying Tesla Powerwall batteries, electric water heaters, and rooftop solar at 40 homes. Homeowners had a dynamic, time-of-use tariff, took advantage of fluctuating prices, and used their batteries to provide ancillary services to Enpuls and earn more income.
With older, costlier batteries, the breakeven point for homeowners was about 10 years; but modern and cheaper batteries reduced that timeline to 7 years. To balance intermittent renewable generation, Enpuls found it could use smaller storage to dispatch electricity efficiently.
Supporting Turkey in reaching their renewable energy targets
The DNV GL storage team is performing a feasibility study for combined solar and energy storage solutions. The aim is to provide the Ministry’s Renewable Energy General Directorate with best practices for integrating energy storage in the upcoming solar auctions.
The project is part of Turkey’s strategic plan to reach the national renewable energy target of 30% of the total electricity generated from renewable source by 2030. DNV GL is working to identify specific prequalification and technical specification requirements that can lead to a lower levelized cost of energy from solar power in the country.
