Every time a new BESS auction hits the headlines, the focus is on one number: the “record low tariff.” But in energy storage, the story doesn’t end there. The ₹/MW/month figure tells only half the tale — it ignores many important aspects which the discoms have to bear. The cheapest bid on paper may not deliver the most reliable, long-lasting energy. It’s time to look inside the box and evaluate the real value of storage systems over their entire lifetime.

Some observations on Baltic ancillary market activations in August: 1) lots of curtailment of electricity production, represented by Down regulations (73 GWh of aFRR + mFRR) --> looks like electricity generation volume is consistently underestimated 2) mFRR Down is 5x of mFRR Up --> the forecast error causing overproduction was visible ~25 minutes before the beginning of a quarter hour, this is the time frame when TSO-s issue mFRR regulation commands 3) aFRR Up vs aFRR Down numbers are similar --> after TSO-s had balanced production and consumption using mFRR commands, production and consumption were roughly in balance as 4 second commands were issued roughly evenly in both directions. For me, the 60 GWh figure appears very large. I'll need to check further, what were the proportions in previous months.

The first draft of the Power Purchase Agreement was completely unbankable. That's more common than you might think. Many developing countries publish a template PPA for renewable energy projects. On paper, this looks efficient. In practice, those templates often fall far short of what’s needed to raise finance. The types of issues we see include: - A buyer with poor credit and no government guarantee - Developers forced to take grid and curtailment risks - Limited protection if the law or regulations change - Weak remedies on termination or political force majeure - Uncertainty around currency convertibility and offshore transfers - Lack of clear arbitration mechanism to resolve disputes - Term too short to repay the financing On those terms, it's impossible for an international lender to finance the project. As legal advisors, this is where we add value. We analyse risk allocation and negotiate the PPA into a version that lenders will actually accept. Fun(?) fact: I once spent 8 years negotiating a PPA with a state-owned power company. The PPA is the foundation for the entire financing. Get it right and everybody wins. Get it wrong and the project never gets built. 👉 I'm Kristian. I help sponsors, investors, and lenders get global energy, infrastructure and tech transactions structured and closed.

Welcoming a big shift in the electricity market.⚡ From today, Europe's day-ahead market is opening a 15-minute trading option, unlocking new opportunities for energy companies. So what does it all mean? 📈 This day-ahead 15-minute forecast gives market participants stronger pricing signals, creating a more accurate picture of price volatility for energy companies to trade against. 🔄 Power demand and renewable generation don't move in neat hourly blocks. They change constantly. 15-minute signals better match that reality, cutting forecast errors and imbalance across the system. 🏡 As more smart devices come onto the grid, it's more crucial than ever to engage with customers to match their demand to market signals. This change could enable cheaper charging windows, lower bills, and happier customers benefitting from more flexible energy. At Kaluza, we’re building the Energy Intelligence Platform that adapts to how people live, and we don’t wait for the rulebook to change - we’ve already been optimising EV charging every 15 minutes using forecasts to capture that extra value for over a year. As the market evolves, we continue to innovate with new optimisation capabilities and orchestrate billions of data points in real time, to build tomorrow’s electrified future. Ready to unlock the future of energy? Let's talk 👉 https://lnkd.in/eciy67vZ #energyoptimisation #energytrading #energyintelligence
