There being a price difference between business and residential does not imply a subsidy. It can simply cost more to distribute electricity to businesses, the time power is supplied may be different, and the nature of what is supplied may also be different. Commonly (in the US) businesses have larger supplies, three phase power, and lines and transformers may be buried or harder to access. Midday electricity is also more expensive typically and businesses use more electricity midday (which is why it is more expensive). Further, businesses may be charged real time rates while residential rates lag spikes in price or are averaged over time. That said, Kazakhstan may subsidize their power, I don’t know.
