independent implementation experts. E&M: So what is possible today in terms of carbon savings with hybrid solutions? MS: Technically, 100% is feasible, but today this can hardly be achieved without a significant energy cost increase. To save or hedge energy cost, most of our clients opt forsolar PV as it is quick and easy to deploy. In most cases, solar PV can thus supply 20% to 30% of energy, up to 50% when adding a larger battery. Every location will have its own renewable profile, but if you have good wind, you may achieve 60-70% renewables without the need for huge batteries. Without wind, using only solar PV & battery, it may not be cost efficient to go beyond 40-50% renewable share at today’s prices for storage. With future reduction in battery prices, the share that can be integrated cost efficiently using PV & battery will grow, thus expanding the system will be an increasingly attractive option. Our recommendation is a stepwise approach, taking advantage as technologies and cost improve: e.g., starting with a 20-25% of renewables and start saving cost as soon as possible while keeping technology options open to do the next step to e.g. 3050% thereafter. Over the last ten years, equipment prices have continuously fallen steeper than anticipated in projections. Looking at the developments and dynamics in the renewable industry, we believe this is likely to continue and will overcome the current surge in prices for modules, steel and logistics.
