m+ energy
m+ energy is a technical and commercial advisory practice for battery storage, renewable integration, industrial power strategy, grid flexibility and microgrids across Asia Pacific. Most storage proposals we are asked to review price the battery correctly and size it wrong. The answer is usually already sitting in the interval data, the tariff schedule and the offtake contract.
We work between engineering, regulation, operations and finance, and we are willing to tell a client the project does not work. Some of the more useful engagements have ended with a recommendation to build smaller, to phase, or not to build.
A data centre site in northern Taiwan with a 5,000 kW contract returned a near zero internal rate of return on pure time of use arbitrage at prevailing installed cost, before subsidy. Additional off peak contract capacity widened the charging window without improving the return, because the arbitrage spread was the binding constraint, not the charging headroom.
A science park facility modelled at roughly 19 percent discharge utilisation and about 70 equivalent full cycles per year. The asset was being paid for as infrastructure and used as insurance.
A textile plant running a heavy round the clock base load could not reach its target contract capacity at any battery size. Two of the largest savings lines in the original business case were arithmetic errors in the tariff logic rather than optimistic assumptions.
Six markets, four of them active. Each market page states which instruments are in force, what they require, and what still has to be confirmed locally.
